The Muon g-2 experiment searches for signs of new particles and forces by precisely measuring the magnetic moment of the muon and comparing it to similarly exact theoretical predictions. A previous experiment performed two decades ago at Brookhaven National Laboratory revealed an intriguing hint of such new physics. The first result of the Fermilab Muon g-2 experiment agrees with the previous experiment and increases the tension between the experiment and the Standard Model to 4.2 sigma. This result will be presented along with description of the experimental methods and theoretical implications. Future prospects of improving the experimental and theoretical uncertainties will be discussed.

The formation of patterns in nature is often determined by the interplay of noise and interactions of different range. Numberless examples are encountered in everyday life and can be described classically. In the nano-world, where the laws of quantum physics are dominant, our understanding is still in its infancy. The dynamics of a quantum many-body system subject to interactions, dissipation and driving forces poses severe theoretical challenges. Understanding the quantum dynamics of these pattern formation processes is an important question of fundamental research and a crucial issue for quantum technological applications, where one aims at robust quantum coherent dynamics in systems of mesoscopic size. A promising and flourishing approach to tackle these questions is offered by the study of ultracold ensembles of atoms coupled to the light fields of high-finesse optical cavities. In these systems quantum structures of photons and atoms emerge from a quantum nonlinear interaction between scattering particles in the presence of noise and dissipation. The inter-atomic interactions are here mediated by multiple scattering of cavity photons and have a long-range character, which makes these systems a unique platform for shedding light into dynamics predicted in other fields of physics, ranging from nuclear physics, nonlinear dynamics, and astrophysics. In this talk I will discuss the basic physical mechanisms leading to crystalline structures of photons and atoms and will review insights gained by theoretical and experimental studies of these systems.
