Brownian-motion approach to statistical mechanics: Langevin equations, fluctuations, and timescales
Sushanta Dattagupta, Aritra Ghosh
We briefly review the problem of Brownian motion and describe some intriguing facets. The problem is first treated in its original form as enunciated by Einstein, Langevin, and oth…
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…
Energetics of the dissipative quantum oscillator
Aritra Ghosh, Jasleen Kaur, Malay Bandyopadhyay
In this paper, we discuss some aspects of the energetics of a quantum Brownian particle placed in a harmonic trap, also known as the dissipative quantum oscillator. Based on the fl…
