Periodically driven thermodynamic systems under vanishingly small viscous drives

S Awasthi, SB Dutta - Physical Review E, 2025 - APS
Periodically driven thermodynamic systems support stable nonequilibrium oscillating states
with properties drastically different from equilibrium. They exhibit even more exotic features …

Oscillating states of periodically driven anharmonic Langevin systems

S Awasthi, SB Dutta - Physical Review E, 2021 - APS
We investigate the asymptotic distributions of periodically driven anharmonic Langevin
systems. Utilizing the underlying SL 2 symmetry of the Langevin dynamics, we develop a …

Oscillating states of driven Langevin systems under large viscous drives

S Awasthi, SB Dutta - Physical Review E, 2022 - APS
We provide a perturbative scheme that is suitable to study oscillating states in driven
Langevin systems in the large viscous regime. We explicitly determine the oscillating state …
