Quantum fluctuations and chaos in fully connected spin models
Aleksandra A. Ziolkowska, Aleksandr N. Mikheev
We investigate beyond-mean-field dynamics in a fully connected spin-exchange model, focusing on the interplay between chaotic dynamics and quantum fluctuations. Us…

Prethermalization of light and matter in cavity-coupled Rydberg arrays
Aleksandr N. Mikheev, Hossein Hosseinabadi, Jamir Marino
We explore the dynamics of two-dimensional Rydberg atom arrays coupled to a single-mode optical cavity, employing nonequilibrium diagrammatic techniques to capture nonlinearities a…
