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…
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 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…
Single and entangled atomic systems in thermal bath and the Fulling-Davies-Unruh effect
Arnab Mukherjee, Sunandan Gangopadhyay, Archan S. Majumdar
In this study, we revisit the Fulling-Davies-Unruh effect in the context of two-level single and entangled atomic systems that are static in a thermal bath. We consider the interac…
Entanglement degradation as a tool to detect signatures of quantum gravity
Soham Sen, Arnab Mukherjee, Sunandan Gangopadhyay
We investigate entanglement degradation in the vicinity of a quantum corrected black hole. We consider a biprtite system (Alice-Rob) with Alice freely falling (radially) into the e…
Fulling-Davies-Unruh effect for accelerated two-level single and entangled atomic systems
Arnab Mukherjee, Sunandan Gangopadhyay, A. S. Majumdar
We investigate the transition rates of uniformly accelerated two-level single and entangled atomic systems in empty space as well as inside a cavity. We take into account the inter…
Unruh quantum Otto engine in the presence of a reflecting boundary
Arnab Mukherjee, Sunandan Gangopadhyay, A. S. Majumdar
We introduce a new model of relativistic quantum analogue of the classical Otto engine in the presence of a perfectly reflecting boundary. A single qubit acts as the working substa…
Analytic (non)integrability of Arutyunov-Bassi-Lacroix model
Jitendra Pal, Arnab Mukherjee, Arindam Lala +1
We use the notion of the gauge/string duality and discuss the Liouvillian (non) integrability criteria for string sigma models in the context of recently proposed Arutyunov-Bassi-L…
Photon velocity, power spectrum in Unruh effect with modified dispersion relation
Arnab Mukherjee, Sunandan Gangopadhyay, Manjari Dutta
In this paper we propose a new form of generalized uncertainty principle which involves both a linear as well as a quadratic term in the momentum. From this we have obtained the co…
Oscillatory power spectrum and strongly -dependent in hybrid inflation
R. Kabir, A. Mukherjee
For the original hybrid inflation model, we calculate the power spectrum of curvature perturbations generated during the waterfall, taking into account the contribution of entropic…
