Decoherence of a charged Brownian particle in a magnetic field : an analysis of the roles of coupling via position and momentum variables
Suraka Bhattacharjee, Koushik Mandal, Supurna Sinha
The study of decoherence plays a key role in our understanding of the transition from the quantum to the classical world. Typically, one considers a system coupled to an external b…
Decoherence and the ultraviolet cutoff: non-Markovian dynamics of a charged particle in a magnetic field
Suraka Bhattacharjee, Koushik Mandal, Supurna Sinha
We derive a non-Markovian master equation for a charged particle in a magnetic field coupled to a bath and study decoherence by analysing the temporal decay of the off-diagonal ele…
Quantum Langevin Equation of a spin in a magnetic field : an analysis
Suraka Bhattacharjee, Koushik Mandal, Supurna Sinha
We derive a quantum Langevin equation for a quantum spin in the presence of a magnetic field and study its dynamics in the Markovian limit using the Ohmic bath model. We extend our…
