Dynamics of fluctuation correlation in periodically driven classical system
Aritra Kundu, Atanu Rajak, Tanay Nag
Having established the fact that interacting classical kicked rotor systems exhibit long-lived prethermal phase with quasi-conserved average Hamiltonian before entering into chaoti…

Stability, Isolated Chaos, and Superdiffusion in Nonequilibrium Many-Body Interacting Systems
Atanu Rajak, Itzhack Dana
We demonstrate that stability and chaotic-transport features of paradigmatic nonequilibrium many-body systems, i.e., periodically kicked and interacting particles, can deviate sign…

Characterizations of prethermal states in periodically driven many-body systems with unbounded chaotic diffusion
Atanu Rajak, Itzhack Dana, Emanuele G. Dalla Torre
We introduce well-defined characterizations of prethermal states in realistic periodically driven many-body systems with unbounded chaotic diffusion of the kinetic energy. These sy…
