Topological energy pumping in a quasi-periodically driven four-level system
Vansh Kaushik, Sayan Choudhury, Tanay Nag
We investigate a quasi-periodically driven four-level system that serves as a temporal analog of topological phenomena found in four-band models with intertwined spin and orbital d…
Robust continuous symmetry breaking and multiversality in the chiral Dicke model
Nikolay Yegovtsev, Sayan Choudhury, W. Vincent Liu
The Dicke model (DM) serves as a paradigm for understanding collective light-matter interactions. We introduce the chiral Dicke model, a generalization where an atomic ensemble cou…
Quantum quenches in a spin-1 chain with tunable symmetry
Luis Eduardo Ramos-SolÃs, Sayan Choudhury, Freddy Jackson Poveda-Cuevas +1
In recent years, the dynamics of interacting quantum systems far from equilibrium have attracted significant research interest. Driven by rapid progress in quantum simulators, vari…
Heating suppression via two-rate random and quasiperiodic drive protocols
Krishanu Ghosh, Sayan Choudhury, Diptiman Sen +1
We study a random and quasiperiodically driven one-dimensional non-integrable PXP spin chain in a magnetic field for two distinct drive protocols. Each of these protocols involves…
Proposal for many-body quantum chaos detection with single-site measurements
IsaÃas Vallejo-Fabila, Adway Kumar Das, Sayan Choudhury +1
We demonstrate that the long-time dynamics of an observable associated with a single lattice site is sufficient to determine whether a many-body quantum system exhibits level stati…
Prethermalization in aperiodically driven classical spin systems
Sajag Kumar, Sayan Choudhury
Periodically driven classical many-body systems can host a rich zoo of prethermal dynamical phases. In this work, we extend the paradigm of classical prethermalization to aperiodic…
