A Coupled Quantum Otto Cycle
George Thomas, Ramandeep S. Johal
We study the 1-d isotropic Heisenberg model of two spin-1/2 systems as a quantum heat engine. The engine undergoes a four-step Otto cycle where the two adiabatic branches involve c…

Universal efficiency at optimal work with Bayesian statistics
Ramandeep S. Johal
If the work per cycle of a quantum heat engine is averaged over an appropriate prior distribution for an external parameter , the work becomes optimal at Curzon-Ahlborn efficien…
