Renormalization group improved cosmology in the presence of a stiff matter era
Gopinath Guin, Soham Sen, Sunandan Gangopadhyay
In \href{https://link.aps.org/doi/10.1103/PhysRevD.92.103004}{Phys. Rev. D 92 (2015) 103004}, simple analytical solutions of the Friedman equations were obtained for a universe hav…
Quantum nature of gravity in a Bose-Einstein condensate
Soham Sen, Sunandan Gangopadhyay
The effect of noise induced by gravitons on a Bose-Einstein condensate has been explored in (Phys. Rev. D 110 (2024) 026014; https://link.aps.org/doi/10.1103/PhysRevD.110.026014).…
Thermodynamics of a Schwarzschild black hole surrounded by quintessence in the generalized uncertainty principle framework
Soham Sen, Abhijit Dutta, Sunandan Gangopadhyay
We investigate the thermodynamics of a Schwarzschild black hole, surrounded by the quintessence energy-matter in the linear and quadratic generalized uncertainty principle framewor…
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…
Quantum gravity signatures in gravitational wave detectors placed inside a harmonic trap potential
Soham Sen, Sunandan Gangopadhyay, Sukanta Bhattacharyya
In this work, we consider a general gravitational wave detector of gravitational wave interacting with an incoming gravitational wave carrying plus polarization only placed inside…
Atom falling into a quantum corrected charged black hole and HBAR entropy
Arpita Jana, Soham Sen, Sunandan Gangopadhyay
In an earlier analysis \href{https://link.aps.org/doi/10.1103/PhysRevD.105.085007}{Phys. Rev. D 105 (2022) 085007}, we have explored the event of acceleration radiation for an atom…
Bose-Einstein condensate as a quantum gravity probe; "Erste Abhandlung"
Soham Sen, Sunandan Gangopadhyay
We consider a Bose-Einstein condensate interacting with a gravitational wave for the case when the gravitational fluctuations are quantized in order to incorporate quantum gravity…
Probing the quantum nature of gravity using a Bose-Einstein condensate
Soham Sen, Sunandan Gangopadhyay
The effect of noise induced by gravitons has been investigated using a Bose-Einstein condensate. The gravitational wave perturbation is then considerd as a sum of discrete Fourier…
