behavior of statistically distinct bosonic and fermionic Stirling cycles with regenerative …

[HTML][HTML] Universal behavior of the coulomb-coupled fermionic thermal diode

S Ghosh, N Gupt, A Ghosh - Entropy, 2022 - mdpi.com
We propose a minimal model of a Coulomb-coupled fermionic quantum dot thermal diode
that can act as an efficient thermal switch and exhibit complete rectification behavior, even in …

Introduction to quantum thermodynamic cycles

S Kumar, N Gupt, S Ghosh, A Ghosh - Journal of Chemical Sciences, 2023 - Springer
Thermodynamics and quantum mechanics are fields in which extensive research has been
done separately. Only in recent years has work been done at the intersection of the two …

Top-ranked cycle flux network analysis of molecular photocells

N Gupt, S Ghosh, A Ghosh - Physical Review E, 2023 - APS
We introduce a top-ranked cycle flux ranking scheme of network analysis to assess the
performance of molecular junction solar cells. By map** the Lindblad master equation to …

Transport of finite size particles in confined narrow channels: Diffusion, coherence, and particle separation

BQ Ai, JC Wu - The Journal of chemical physics, 2013 - pubs.aip.org
Transport of the finite size spherical Brownian particles is investigated in confined narrow
channels with varying cross-section width. Applying the Fick-Jacobs approximation, we …

Rectification of self-propelled particles in entropic barriers: finite size effects

JC Wu, Q Chen, R Wang, BQ Ai - Journal of Physics A …, 2014 - iopscience.iop.org
Transport of finite size self-propelled particles is numerically investigated in a two-

Microscopic theory of heat transfer between two fermionic thermal baths mediated by a spin system

S Ray, BC Bag - Physical Review E, 2015 - APS
In this paper we have presented the heat exchange between the two fermionic thermal
reservoirs which are connected by a fermionic system. We have calculated the heat flux …

Nonequilibrium entropic temperature and its lower bound for quantum stochastic processes

S Ray, A Baura, BC Bag - Physical Review E, 2014 - APS
In this paper, we have studied the Shannon “entropic” nonequilibrium temperature (NET) of
quantum Brownian systems. The Brownian particle is attached to either a bosonic or …

Parametrically coupled fermionic oscillators: Correlation functions and phase-space description

A Ghosh - Physical Review A, 2015 - APS
A fermionic analog of a parametric amplifier is used to describe the joint quantum state of the
two interacting fermionic modes. Based on a two-mode generalization of the time-dependent …

[PDF][PDF] Quantum Dissipation in a spin bath; Application to Chemical Dynamics

A Ghosh, SS Sinha, DS Ray - Proc. Indian Acad. Sci. Sect. A, 2014 - academia.edu
It is our everyday experience that any macroscopic physical system cannot be completely
isolated from its surrounding. As a consequence energy accumulated in a system must be …
