Quantum Thermal Logic Gates
Shuvadip Ghosh, Arnab Ghosh, Bivas Dutta +1
We propose a new concept for quantum thermal logic gates -- analogous to classical electronic logic gates -- that exploit the heat current in a coupled quantum-dot system tunnel-co…
Thermodynamics of Quantum Coupled Transport
Shuvadip Ghosh, Arnab Ghosh
This review presents a thermodynamic perspective on quantum coupled transport processes in nanoscale systems. Our analysis is formulated within the framework of entropy production…
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,…
Top-Ranked Cycle Flux Network Analysis of Molecular Photocells
Nikhil Gupt, Shuvadip Ghosh, Arnab Ghosh
We introduce a top-ranked cycle flux ranking scheme of network analysis to assess the performance of molecular junction solar cells. By mapping the Lindblad master equation to the…
Universal behaviour of Coulomb coupled Fermionic thermal diode
Shuvadip Ghosh, Nikhil Gupt, Arnab Ghosh
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 behaviour, even i…
