Real-Time Formation of a Landau Polaron
Priya Nagpal, Arnab Ghosh, Helene Seiler +2
Polarons are electronic excitations dressed by a self-consistent lattice distortion, yet their formation has not been directly resolved in real time. We develop a microscopic lines…
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…
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…
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…
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 [Wang et al., Phys. Rev. Lett. 124, 110607 (2020)] -- where an induced current flows opposit…
Graph theoretic analysis of three-terminal quantum dot thermocouples: Onsager relations and spin-thermoelectric effects
Nikhil Gupt, Shuvadip Ghosh, Arnab Ghosh
We introduce a simplified model for a three-terminal quantum thermocouple consisting of two strongly-coupled quantum dots. To elucidate spin-dependent Seebeck and Peltier effects,…
