Enhancement of an Unruh-DeWitt battery performance through quadratic environmental coupling
Arnab Mukherjee, Sunandan Gangopadhyay, A. S. Majumdar
We investigate relativistic effects on the performance of a quantum battery in an open quantum framework. We consider an Unruh-DeWitt detector driven by a coherent classical pulse…
Quantum regression theorem in the Unruh-DeWitt battery
Manjari Dutta, Arnab Mukherjee, Sunandan Gangopadhyay
In this paper, we employ the quantum regression theorem, a powerful tool in the study of open quantum systems, to analytically study the correlation functions of an Unruh-DeWitt de…
Transition rates and their applications in accelerated single-qubit for fermionic spinor field coupling
Arnab Mukherjee, Sunandan Gangopadhyay, P. H. M. Barros +1
In this work, we investigate the interaction between a uniformly accelerated single qubit and a fermionic spinor field. Here we consider both the massless and the massive fermionic…
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…
Relativistic quantum Otto engine driven by the circular Unruh effect
Rudra Prosad Sarkar, Arnab Mukherjee, Sunandan Gangopadhyay
In this work, we present a new framework for a relativistic quantum analouge of the classical Otto engine. Considering a single qubit as the working substance, we analyse its inter…
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…
