Success for doctoral students in theoretical physics: two publications in Physical Review Letters

Two working groups from theoretical non-linear physics have reason to celebrate: under the leadership of Prof. Thiele and Prof. Gurevich, groundbreaking scientific work was recently published independently in the renowned journal Physical Review Letters.

Together with an international collaboration, Thomas Seidel presented a study entitled “Multistable Kuramoto Splay States in a Crystal of Mode-Locked Laser Pulses”. This work investigates mode-locked lasers using theoretical and experimental methods and describes multistable states in the phase relations of the pulses. The research team shows how they are linked to optical frequency combs and provides experimental evidence. These findings offer new perspectives for applications in high-precision spectroscopy and photonics.

Daniel Greve, on the other hand, investigated the interactions between non-reciprocity and conservation laws in active multicomponent systems in his work “Coexistence of Uniform and Oscillatory States Resulting from Nonreciprocity and Conservation Laws”. The results demonstrate that such systems not only allow stable uniform and oscillatory states, but also their coexistence. In certain cases, this coexistence can be described and predicted by a generalized Maxwell construction.

Both works impressively demonstrate how nonlinear methods broaden and deepen our understanding of complex physical systems.
