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…
Derivative coupling in horizon brightened acceleration radiation: a quantum optics approach
Ashmita Das, Anjana Krishnan, Soham Sen +1
Horizon Brightened Acceleration Radiation (HBAR) signifies a unique radiation process and provides a promising framework in exploring acceleration radiation in flat/ curved spaceti…
Inverse logarithmic correction in the HBAR entropy of an atom falling into a renormalization group improved charged black hole
Arpita Jana, Soham Sen, Sunandan Gangopadhyay
In this work, we have considered a spherically symmetric non-rotating charged black hole geometry where both the Newton's gravitational constant and the charge of the black hole fl…
