Fate of Quantum Scars and Chaos-Assisted Tunneling under Dissipation
Debabrata Mondal, Sohan Pati, S. Sinha +1
Quantum scars enable memory and recurrent dynamics, but their fate under dissipation remains poorly understood. Here, we show that distinct quantum scars can respond qualitatively…
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…
Emergence of a quasi-ergodic steady state in a dissipative Tavis-Cummings array
Debabrata Mondal, K. Sengupta, Subhasis Sinha
In an atom-photon interacting system described by Tavis Cummings Hubbard (TCH) model, we demonstrate the emergence of a quasi-steady state in a dissipative environment that exhibit…
Nonequilibrium dynamics of the Jaynes-Cummings dimer
G. Vivek, Debabrata Mondal, S. Sinha
We investigate the nonequilibrium dynamics of a Josephson-coupled Jaynes-Cummings dimer in the presence of Kerr nonlinearity, which can be realized in the cavity and circuit quantu…
Classical route to ergodicity and scarring phenomena in a two-component Bose-Josephson junction
Debabrata Mondal, Sudip Sinha, Sayak Ray +2
We consider a Bose-Josephson junction (BJJ) formed by a binary mixture of ultracold atoms to investigate the manifestation of coherent collective dynamics on ergodicity and quantum…
