Quantum coherence measures in entangled atomic systems
Arnab Mukherjee, Soham Sen, Sunandan Gangopadhyay
In this study, we investigate the effect of the Lorentz transformation on the measures of quantum coherence in an entangled atomic system. Here, we consider the effect of this rela…
Density matrix analysis of systems influenced by periodic Hamiltonians
Soham Sen, Manjari Dutta, Sunandan Gangopadhyay
In this work, we consider simple systems that are influenced by Hamiltonians with time periodicity. Our analysis is mainly focussed on the density matrix approach and aims to solve…
Quantum coherence measures for generalized Gaussian wave packets under a Lorentz boost
Arnab Mukherjee, Soham Sen, Sunandan Gangopadhyay
In this paper we consider a single particle, spin-momentum entangled state and measure the effect of relativistic boost on quantum coherence. The effect of the relativistic boost o…
Virtual transitions in an atom-mirror system in the presence of two scalar photons
Ashmita Das, Soham Sen, Sunandan Gangopadhyay
We examine the virtual transition of an atom-mirror system with the simultaneous emission of two scalar photons, where the atom and the mirror admit a relative acceleration between…
