Cross-Spectral Reservoir Correlations as a Resource for Finite-Time Quantum Otto Engines
Siddhartha Dutta, Sujay Mondal, Ankush Das +2
We investigate the thermodynamic consequences of longitudinal-transverse cross-spectral reservoir correlations in a finite-time quantum Otto engine with a two-level working medium.…

Effect of Cross-Spectral Correlations on Qubit Dynamics: Coherence Revival and Relaxation Modulation
Siddhartha Dutta, Sujay Mondal, Abhijit Bandyopadhyay
We investigate the reduced dynamics of a qubit subject to correlated longitudinal and transverse noise arising from its coupling to a shared bosonic bath. The environmental fluctua…

Tensor-Network-Based Unraveling of Non-Markovian Dynamics in Large Spin Chains via the Influence Martingale Approach
Sujay Mondal, Siddhartha Dutta, Abhijit Bandyopadhyay
Classical simulation of open quantum system dynamics remains challenging due to the exponential growth of the Hilbert space, the need to accurately capture dissipation and decohere…
