Chaos to Synchronization and Dissipative Quantum Scarring in Open Coupled top-Dicke model in a Lossy Cavity
Debabrata Mondal, Sohan Pati, S. Sinha
We present a variant of the Dicke model, termed as the open coupled-top Dicke model, which enables the exploration of rich non-equilibrium phenomena, particularly the fate of quant…
Dissipation as a Resource: Synchronization, Coherence Recovery, and Chaos Control
Debabrata Mondal, Lea F. Santos, S. Sinha
Dissipation is commonly regarded as an obstacle to quantum control, as it induces decoherence and irreversibility. Here we demonstrate that dissipation can instead be exploited as…
Transient and steady-state chaos in dissipative quantum systems
Debabrata Mondal, Lea F. Santos, S. Sinha
Dissipative quantum chaos plays a central role in the characterization and control of information scrambling, non-unitary evolution, and thermalization, but it still lacks a precis…
Dissipative chaos and steady state of open Tavis-Cummings dimer
Debabrata Mondal, Andrey Kolovsky, S. Sinha
We consider a coupled atom-photon system described by the Tavis-Cummings dimer (two coupled cavities) in the presence of photon loss and atomic pumping, to investigate the quantum…
Self-trapping phenomenon, multistability and chaos in open anisotropic Dicke dimer
G. Vivek, Debabrata Mondal, Subhadeep Chakraborty +1
We investigate semiclassical dynamics of a coupled atom-photon interacting system described by a dimer of anisotropic Dicke model in the presence of photon loss, exhibiting a rich…
