Relativistic Quantum Otto Engine: Generalized efficiency bounds and frictional effects
Vahid Shaghaghi, Pritam Chattopadhyay, Vijit V. Nautiyal +3
This work investigates a relativistic quantum Otto engine with a harmonic oscillator as its working medium, analyzing how relativistic motion and nonadiabatic driving affect its pe…
The asymmetric Otto engine: frictional effects on performance bounds and operational modes
Varinder Singh, Vahid Shaghaghi, Tanmoy Pandit +3
We present a detailed study of an asymmetrically driven quantum Otto engine with a time-dependent harmonic oscillator as its working medium. We obtain analytic expressions for the…
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…
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…
Extracting work from random collisions: A model of a quantum heat engine
Vahid Shaghaghi, G. Massimo Palma, Giuliano Benenti
We study the statistical distribution of the ergotropy and of the efficiency of a single-qubit battery ad of a single-qubit Otto engine, respectively fuelled by random collisions.…
