Quantum Thermal Analogs of Electric Circuits: A Universal Approach
Devvrat Tiwari, Samyadeb Bhattacharya, Subhashish Banerjee
In this work, we develop a panoramic schematic of quantum thermal analogs of electric circuits in the steady state regime. We establish the foundations of said premise by defining…
Quantum Thermodynamics of Open Quantum Systems: Nature of Thermal Fluctuations
Neha Pathania, Devvrat Tiwari, Subhashish Banerjee
We investigate the thermodynamic behavior of open quantum systems through the Hamiltonian of Mean Force, focusing on two models: a two-qubit system interacting with a thermal bath…
Quantum speed limit and nonclassicality in open quantum system models using the Wigner function
Arti Gaharwar, Devvrat Tiwari, Subhashish Banerjee
The quantum speed limit and the Wigner function of open system models are studied. To this end, we use the phase covariant and a two-qubit model interacting with a squeezed thermal…
Bipartite OTOC in open quantum systems: information scrambling and irreversibility
Baibhab Bose, Devvrat Tiwari, Subhashish Banerjee
The field of information scrambling has seen significant growth over the last decade, where the out-of-time-ordered correlator (OTOC) has emerged as a prominent tool to probe it. I…
Strong coupling non-Markovian quantum thermodynamics of a finite-bath system
Devvrat Tiwari, Baibhab Bose, Subhashish Banerjee
The focus is on understanding the quantum thermodynamics of strongly coupled non-Markovian quantum systems. To this end, a non-trivial, non-Markovian model of a central spin surrou…
