Experimental investigation of a quantum Otto heat engine with shortcuts to adiabaticity implemented using counter-adiabatic driving
Krishna Shende, Matreyee Kandpal, Arvind +1
The finite time operation of a quantum Otto heat engine leads to a trade-off between efficiency and output power, which is due to the deviation of the system from the adiabatic pat…

Experimental investigation of coherence contributions to a nonequilibrium thermodynamic process in a driven quantum system
Krishna Shende, Kavita Dorai, Arvind
The work done when a system at thermal equilibrium is externally driven by a unitary control parameter leads to irreversible entropy production. The entropy produced can be thought…

Using a quantum SWAP engine to experimentally validate thermodynamic uncertainty relations
Krishna Shende, Arvind, Kavita Dorai
Thermodynamic uncertainty relations (TURs) arise from the bounds on fluctuations of thermodynamics quantities during a non-equilibrium process and they impose constraints on the co…
