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…

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,…
