Stochastic thermodynamics and the Ericsson nano engine -- Efficiency from equilibrium results
Jasleen Kaur, Aritra Ghosh, Sushanta Dattagupta +2
In this work, we study an Ericsson cycle whose working substance is a charged (quantum) oscillator in a magnetic field that is coupled to a heat bath. The resulting quantum Langevi…

Weak-coupling limits of the quantum Langevin equation for an oscillator
Aritra Ghosh, Sushanta Dattagupta
The quantum Langevin equation as obtained from the independent-oscillator model describes a strong-coupling situation, devoid of the Born-Markov approximation that is employed in t…
