Quantum Langevin dynamics and the long-time behaviour of two charged coupled oscillators in a common heat bath
Koushik Mandal, Suraka Bhattacharjee
In this paper, the moderately long-time behaviours of the correlation functions for two charged coupled harmonic oscillators connected to a common heat bath are analyzed in the pre…

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…
