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,…
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…
Floquet Quantum Thermal Transistor
Nikhil Gupt, Srijan Bhattacharyya, Bikash Das +3
We apply periodic control to realize a quantum thermal transistor, which we term as the Floquet Quantum thermal Transistor. Periodic modulation allows us to control the heat flows…
Statistical Generalization of Regenerative Bosonic and Fermionic Stirling Cycles
Nikhil Gupt, Srijan Bhattacharyya, Arnab Ghosh
We have constructed a unified framework for generalizing the finite-time thermodynamic behavior of statistically distinct bosonic and fermionic Stirling cycles with regenerative ch…
