DPG Meeting of the Condensed Matter Section, Berlin

Recently, many members of our research group had the opportunity to attend the DPG Meeting of the Condensed Matter Section in Berlin. This annual gathering allowed us to showcase our research results, which we have compiled over the past few months, through both posters and presentations. Beyond presenting our own research, the meeting served as an ideal platform for learning from and interacting with other researchers.

In addition to participating in the conference, we also had the chance to explore the vibrant city of Berlin and enjoy other group activities.

We are grateful for the opportunity to participate in the conference and are looking forward to next year's event.

Nature paper with Columbia — Gravitons in FQHE liquid

Together with colleagues from Columbia University (USA), Princeton University (USA), and Nanjing University (China), we report in the journal Nature on the first experimental evidence of collective excitations with spin called chiral graviton modes (CGMs) in a semiconducting material. This graviton modes are the solid-state analogue to a graviton, a yet-to-be-discovered elementary particle better known in high-energy quantum physics for hypothetically giving rise to gravity. Gravity is one of the fundamental forces in the universe. The graviton-like quasi-particle has been discovered in fractional quantum Hall liquids hosted in an ultra-clean gallium arsenide based heterostructure. Further studies of CGMs could support to develop a better understanding of the links between quantum mechanics and Einstein’s theory of relativity.

Columbia's story: A team of scientists from Columbia, Nanjing University, Princeton, and the University of Munster, writing in the journal Nature, have presented the first experimental evidence of collective excitations with spin called chiral graviton modes (CGMs) in a semiconducting material.

New Scientist : We've glimpsed something that behaves like a particle of gravity. Gravitons, the particles thought to carry gravity, have never been seen in space – but something very similar has been detected in a semiconductor. Read more ...

Conferenz at Kirchberg (Tirol)

While visiting the International Winterschool on Electronic Properties of Novel Materials (IWEPNM) 2024 in Kirchberg (Tirol, Austria) our four PhD students Hendrik, Sebastian, Jakob and Pierre-Maurice presented some Poster about their current research topics.

Also, the weather was quite nice to explore the surroundings and to talk outside about new and exciting scientific topics.

EDISON 22 - The 22nd International Conference on Electron Dynamics in Semiconductors, Optoelectronics and Nanostructures - will be held in Münster (Germany), 14 - 18 August 2023. EDISON 22 will highlight the latest progress in the field of fundamental physics and applications of electron dynamics in semiconductors, optoelectronic devices, and nanostructures.

On August 9th, 2023, the working groups of Prof. Wurstbauer and Prof. Krenner met for a joint company outing. After it had only rained many days before, we started our bike tour at 9:30 a.m. with lots of sun and blue skies. The route led us via small Pättkes away from the traffic in the direction of Pleistermühle and then along the Werse to Stapelskotten. The level of the Werse had already risen significantly due to the rainfall over the past few days. From Stapelskotten it went through Wolbeck into the large forest area Tiergarten and then back to the Werse to Albersloh. We didn't let ourselves be discouraged by a broken tire and after the repair with many helpers we went to Frank's house in Albersloh. In the garden everything was already prepared for the BBQ and cool drinks were ready. Numerous delicious and above all homemade salads and side dishes complemented the grilled food. At pleasantly warm temperatures, we savored the liquid and solid food. Towards evening we went back to Münster by bike, but this time without detours. Thanks to everyone for the nice day together.

WE-Heraeus-Seminar - 2D Materials and Hybrids: Hybrid Quasiparticles in Quantum Materials

Quasiparticles and their mutual interactions form the basis for quantum technologies and integrated opto-/electronic circuits with embedded novel functionalities. It is therefore important to understand the underlaying correlations including coherence properties and their dynamics on a very fundamental level. Material platforms hosting such quasiparticles and potentially allowing the implementation of integrated circuitries with intelligent or quantum functionalities are two dimensional (2D) materials and their hybrids formed from e.g. coupling with plasmonic structures. Two-dimensional materials exhibit a rich set of quasiparticle excitations, together with exciting spin and valley properties and topological non-trivial materials. 2D materials such as the intensively studied class of transition metal dichalcogenides (TMDCs), tetradymites, and further 2D materials with distinct topological properties have emerged as a platform to realize, understand and tailor quantum hybrid structures. They can be combined with arbitrary substrates, be twisted, and be assembled into heterostructures. Those 2D materials can be interfaced with plasmonic films and nanostructures to fundamentally study weak and strong interactions, as well as energy and information transfer between the different quasiparticles and for the realization of hybrid quasiparticles that can be integrated in functional units. The aim of the seminar is bringing together a group of excellent internationally well-established researchers working on 2D materials, hybrids and their quasiparticles from various points of views using different characterization tools, materials, or theoretical methods to foster synergy. Young researchers at the PhD or PostDoc levels will be encouraged to actively participate with poster presentations, at a panel discussion and a synergy workshop session.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.

September 2022

Hendrik and Pierre-Maurice visited the FLATLANDS 2022 — 9th Flatlands beyond Graphene on Lanzarote (Spain), where they presented their new results in the poster session.

August 2022

With sun and warm temperatures, a little shower and great views of the surrounding area, the working group started a wonderful company outing in the Teuteburg Forest. It started with the bus from Münster to Dörenthe. At the Dörenther Cliffs parking lot, the working group surprised the birthday child Ursula with a second breakfast. Fresh sandwiches, cold drinks and delicious birthday cake served the working group as a refreshment for the upcoming hike along the Hermannsweg/Teutoschleifen.
Climbing was done on the "Hockendes Weib" and the view of the Münsterland was enjoyed. We continued in the direction of the Dreikaiserstuhl, Königstein-Bocketal Blick and Bismarkturm. Arriving in beautiful Tecklenburg, we took a deserved lunch break. A little rain brought some cooling and the group set out in the direction of the Tecklenburg Königsteiche and the Lengerich Canyon, an old sand-lime quarry that is now a nature reserve. Arriving in the center of Lengerich/train station, we took the train back to Münster.

Time to say good-bye

With mixed feelings we have to say good-bye to our Postdoc Torsten. We will miss you and at the same time we wish you and your family all the best, success and happiness.

Delicious and sportive lunch break at the “Physik Fachschaft Sommerfest”

Many thanks to all organizers and supporters from the student body of the physics faculty for preparing such a nice party even if the weather did not really cooperate. The barbecue with all kind of options was a welcome and very tasty alternative to the student cafeteria and the delicious self-made liquid nitrogen ice-cream is a real insiders’ tip. We are already looking forwrad to this delicious refreshment next year. The study board was really worried about our health and provided a healthy exercise option by the bouncy castle (including free  training of the risible muscles for all).

Quantum Science & Technology Seminar by AG Wurstbauer & AG Schuck

On February 1st we had our last “Quantum Science & Technology Seminar (QST)” seminar held together with the AG Schuck with alternate talks by members of both groups. What was planned and started as hybrid lunch-time “Pizza-Seminar” ended as online seminar - charge it to Covid. Nevertheless, we had exciting talks, intense discussions and learn a lot from the quantum technology and quantum science world and got to know each other such that even two collaborative projects are initiated by the QST seminar.

Wir begrüßen unser neues Arbeitsgruppenmitglied - Herrn Müller. Auch wenn Herr Müller nicht wirklich ein Teamplayer ist und lieber alleine arbeitet, so fügt er sich doch gut in die Arbeitsgruppe ein. Wir freuen uns sehr über seine tatkräftige Unterstützung während der ruhigen Nachtschicht ... ;-)

Physiker der Universität Münster bei Großgeräteinitiative erfolgreich

Deutsche Forschungsgemeinschaft fördert neues Gerät für die Quantenkommunikation

Ein Team vom Physikalischen Institut der Westfälischen Wilhelms-Universität (WWU) Münster war bei der Großgeräteinitiative „Quantenkommunikation“ (QCDE) der Deutschen Forschungsgemeinschaft (DFG) erfolgreich: Die Wissenschaftlerinnen und Wissenschaftler erhalten ein „Millikelvin-Mikrowellen-Photonik-Messsystem“, mit dem Bauelemente für die Quantenkommunikation untersucht werden sollen. Die DFG stellt hierfür rund 2,7 Millionen Euro zur Verfügung. Die Quantenkommunikation gilt als eine der Schlüsseltechnologien der Zukunft, bei der Informationen durch einzelne Lichtquanten, sogenannte Photonen, übertragen werden. Diese Art der Datenübertragung ist nicht nur schnell, sondern vor allem besonders abhörsicher.

Am Physikalischen Institut werden Quantenbauelemente für die Quanteninformationsverarbeitung entwickelt, deren Leistungsfähigkeit die Forschungsgruppen mit dem nun bewilligten Großgerät untersuchen können. Herzstück des neuen Geräts ist ein mit optischen Fasern und Hochfrequenzelektronik ausgestattetes Messsystem, in dem Quanten-Chips auf Temperaturen von nur wenigen Tausendstel Grad über dem absoluten Nullpunkt abgekühlt werden. Mit diesem einzigartigen Gerät sollen einzelne Photonen in atomar dünnen Materialien erzeugt und dabei mithilfe von Nanoschallwellen in bisher unerreichter Präzision getaktet werden. Im selben Gerät können aber auch die passenden in Münster entwickelten supraleitenden Einzelphotonen-Detektoren vermessen werden.

Über den nun bewilligten Antrag freuen sich neben Koordinator Prof. Dr. Hubert Krenner auch Prof. Dr. Ursula Wurstbauer, Prof. Dr. Rudolf Bratschitsch und Prof. Dr. Carsten Schuck, die am Projekt beteiligt sind. Am Physikalischen Institut startet in Kürze der Umbau der Laborräume, in denen das neue Großgerät aufgebaut und für Spitzenforschung zur Verfügung stehen wird. Es bildet eine wichtige Schnittstelle zum im Aufbau befindlichen Department für Quantentechnologie des Fachbereichs Physik der WWU sowie zu externen Kooperationspartnern für die Erforschung neuartiger Quantenbauelemente.

Großgeräteinitiativen der Deutschen Forschungsgemeinschaft

Im Rahmen von Großgeräteinitiativen können Wissenschaftlerinnen und Wissenschaftler bei der DFG aufwändige Großgeräte mit herausragender, innovativer Technik beantragen, mit der besonders zukunftsweisende spezielle wissenschaftliche und technische Fragestellungen untersucht werden können.

Mit der Initiative QCDE möchte die DFG Wissenschaftlern neueste Technologie zugänglich machen, die für die Erforschung von Quantenkommunikations-Systemen eingesetzt wird. QCDE soll dabei ein Schritt hin zur Standardisierung von Quellen, Transmittern und Detektoren für die Quantenkommunikation sein. Bislang werden vielfältige Ansätze vor allem mit hochspezialisierten Laboraufbauten entwickelt und getestet.

Meldung der DFG: Großgeräteinitiativen zur Erforschung von Quantentechnologie

Successfully kicking-off of the new year:

• Our work on “Domain textures in the fractional quantum Hall effect” has been published in  Physical Review Letters and our work on “Optical dipole orientation of interlayer excitons in MoSe2-WSe2 heterostacks” in  Physical Review B.
• Our review article jointly written with AG Bratschitsch (WWU), AG Kuhn (WWU) and our collaboration partner Prof. Holleitner (WSI) on “Single-photon emitters in layered van der Waals materials” is online.
• Together with Torsten, we wrote an invited “Brennpunkt” on “Exotische Exzitonen” for the Physik Journal, the member journal of the German Physical Society (DPG), one of the largest physics society worldwide.

Warm welcome to our new Master student Sven. We look forward to a successful and great time with you.

Also this year we had to change our plans. Due to the current Corona situation we had another virtual Christmas party. We had a lot of fun and team work was required to successfully solve the puzzles in virtual escape room games. Afterwards the relaxing part with lots of fun and laughter started. Big thanks to the hard-working “Secret Santas” 😊. And for sure we will go out for the planned Boßel-competition as soon as the situation allows.

Hamburg: 29.09. – 01.10.2021 - Workshop on nanoelectronics and correlations in 2D materials

Members of the core groups headed by Prof. Wurstbauer (University of Münster) and Prof. Wehling (University of Bremen and University of Hamburg).

The scope of the workshop is to present and discuss the status of ongoing research projects between the individual members of the two groups in order to foster ongoing collaborations. More precise, we intend to stimulate discussion that may lead to new insights, new achievements, novel experimental or theoretical approaches or even to new research projects. The group of Prof. Wehling is focused on theoretical investigations of the electronic structures of (correlated) solid state materials with a strong interest in 2D materials. The focus of the Wurstbauer group is experimentally on the exploration of optical and electronic properties of tailored quantum nano-systems with a strong interest in 2D materials. The groups work already on a joint DFG funded project. This meeting will allow for intense and mutual discussion on the ongoing research project, the technical implementations, the data handling as well as the organization, planning and management of the project. To advance the current work and to promote further collaboration is important that the researchers of both groups know each other, find a common language and communication basis as well as understanding about the scientific methods and skillsets. Due to the ongoing pandemic situation an on-site meeting of the project groups was not yet possible, hence urgently needed.

Moreover, the pandemic situation made typical meetings and conferences in presence impossible such that in particular the younger / newer members of the groups on all levels could not practice scientific and/or project related spontaneous presentations, explanations and discussions that are highly important for a successful and efficient development of projects at academia and beyond. The workshop provides an intense training on scientific communication with an emphasize on transferring ideas, overarching goals, achievements and challenges by a free speech (without support by slides or other media). There will be ample time for practice and feedback rounds on both, the communication skill as well as the scientific content. All participants mandatorily contribute to both parts, by giving speeches and participate in the feedback discussions.

The workshop will be held in appliance with the current Corona regulations from both universities and the City of Hamburg. The schedule is prepared such that time outside is maximized and time in closed rooms is minimized and limited to smaller subgroups.

Lots of activities in June and July:

We participated at the Leonardo-Campus-Run at the “5000” steps composition as a group having a nice walk around Münster with a lot of fresh air, sun, some laughers and of course sufficient physical distance. Afterwards we refreshed with tasty cold isotonic beverage specially brewed at the “Stone circle” (Thank you Sebastian!).

The mK-System is no equipped with the piezo actuators and the low-temperature objective - and it is still super cold with a record of 7mK with open windows and some light on the sample! Well done to the team in particular Frank and Torsten and of course the team of the Machine Job.

Everything was finished just in time for your guest researcher Flo from Munich who will join us for some exciting measurements on van der Waals heterobilayers.
The characterization set-up I is ready and the time-resolved set-up with the gated ICCD are ready as well. Characterization set-up II is currently planned.  Well done to all, in particular to Nihit together with the others.

Our “kiuty” enjoys the low temperatures and is busy with temperature dependent transport and ellipsometry experiments. Simultaneously, the SIE is running almost continuously – a great team effort!

We organized the first summer school of the SPP2244 “vdW assembly – more than playing Lego” which had to be held virtually. Nevertheless, we had excellent talks, active poster discussions and lab tours, tons of discussions and some chats beyond research.

In this contest: Congrats to Hossein for being elected as student representative of the SPP2244. Many thanks for your service to the community.

End of June: Time to say good bye: Iris and David are moving to their next positions, both in Spain. Iris is doing a Posdoc at the CIC nanoGUNE in San Sebastian and David starts as a PhD student at ICMS-CSIC in Seville. We thank you both for the enjoyable and successful time and wish you all the best for your future in science and beyond and hope to see you again at the one or the other occasion.

Juni 2021: Im Rahmen eines einwöchigen Schulpraktikums konnten Alicia und Johannes interessante Eindrücke aus dem Arbeitsalltag von Physikern/Physikerinnen gewinnen. Neben dem Mitarbeiten in physikalischen Laboren, konnten die beiden aber auch ihre handwerklichen Fähigkeiten ( z.B. beim Löten) testen. Voller Stolz über die komplett selbsterstellte erste CAD-Zeichnung einer Pfeife, ging es anschließend an einen 3D-Drucker, der das kleine Andenken an ihre Zeit bei uns in die reale Welt übertrug.

Juni 2021: Wir heißen unsere beiden Bachelor Studierende Lucie und Msab „Mo“ und unsere Werkstudentin Laura herzlich willkommen. Wir wünschen Euch viel Erfolg und eine tolle gemeinsame Zeit in der AG.

June 2021: We welcome our new Bachlor students Lucie and Msab "Mo" to the group and our working student (SHB) Laura how already did a great job in supporting us with her soldering and exfoliation skills. We wish you all a successful and pleasant time.
