Spin-orbit coupled spin-boson model : A variational analysis

Sudip Sinha, Subhasis Sinha, Sushanta Dattagupta

The spin-boson (SB) model is a standard prototype for quantum dissipation, which we generalize in this work, to explore the dissipative effects on a one-dimensional spin-orbit (SO)…

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…

Independent-oscillator model and the quantum Langevin equation for an oscillator: A review

Aritra Ghosh, Malay Bandyopadhyay, Sushanta Dattagupta +1

This review provides a brief and quick introduction to the quantum Langevin equation for an oscillator, while focusing on the steady-state thermodynamic aspects. A derivation of th…
