Lossy Micromaser Battery: Almost Pure States in the Jaynes-Cummings Regime
Vahid Shaghaghi, Varinder Singh, Matteo Carrega +2
We consider a micromaser model of a quantum battery, where the battery is a single mode of the electromagnetic field in a cavity, charged via repeated interactions with a stream of…
Thermodynamic uncertainty relation in nondegenerate and degenerate maser heat engines
Varinder Singh, Vahid Shaghaghi, Özgür E. Müstecaplıoğlu +1
We investigate the thermodynamic uncertainty relation (TUR), \textit{i.e.} a trade-off between entropy production rate and relative power fluctuations, for nondegenerate three-leve…
Performance analysis of quantum harmonic Otto engine and refrigerator under a trade-off figure of merit
Kirandeep Kaur, Shishram Rebari, Varinder Singh
We investigate the optimal performance of quantum Otto engine and refrigeration cycles of a time-dependent harmonic oscillator under a trade-off figure of merit for both adiabatic…
Micromasers as Quantum Batteries
Vahid Shaghaghi, Varinder Singh, Giuliano Benenti +1
We show that a micromaser is an excellent model of quantum battery. A highly excited, pure, and effectively steady state of the cavity mode, charged by coherent qubits, can be achi…
