Statistical mechanics from quantum envariance and exchange symmetry
Amul Ojha, Shubhit Sardana, Arnab Ghosh
We build on the foundational work of Deffner and Zurek [S. Deffner and W. H. Zurek, New J. Phys. 18, 063013 (2016)] to show how central equilibrium structures of statistical mechan…
Inverse Current in Coupled Transport: A Quantum Thermodynamic Model
Shuvadip Ghosh, Nikhil Gupt, Arnab Ghosh
The recent discovery of inverse current in coupled transport (ICC) in classical systems~\textcolor{blue}{[\textbf{Phys. Rev. Lett.} \textbf{124}, 110607 (2020)]} -- where an induce…
Fluctuations and Irreversibility: Historical and Modern Perspectives
Sounak Bandyopadhyay, Arnab Ghosh
This article traces the development of fluctuation theory and its deep connection to irreversibility, from equilibrium to near-equilibrium, and finally to far-from-equilibrium syst…
Fluctuations and optimal control in a Floquet Quantum Thermal Transistor
Samir Das, Shishira Mahunta, Nikhil Gupt +2
We use Full Counting Statistics to study fluctuations and optimal control in a three-terminal Floquet quantum thermal transistor. We model the setup using three qubits (termed as t…
