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…
Atomic Inversion and Entanglement Dynamics for Squeezed Coherent Thermal States in the Jaynes-Cummings Model
Koushik Mandal, M. V. Satyanarayana
The tussling interplay between the thermal photons and the squeezed photons is discussed. The `classical noise' is represented by the thermal photons and the `quantum noise' is rep…
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…
Atomic and entanglement dynamics in the mixed squeezed coherent state version of the Jaynes-Cummings interaction
Koushik Mandal, Pooja Jethwani, M. Venkata Satyanarayana
Coherent signal containing squeezed noise in a mixed state of radiation field is considered here as a non-Gaussian mixture of a coherent state density operator and a squeezed state…
