Towards graviton lasing from squeezed ultra-cold systems
Soham Sen, Vlatko Vedral
In our recent work, arXiv:2604.11474 [hep-th], we have shown that effective detection of gravitons is possible using an array of charged harmonic oscillators in a dynamical electro…
Post-Newtonian analysis of the quantum signatures of gravity
Tuhin Chatterjee, Soham Sen, Sunandan Gangopadhyay
In a recent work \href{https://doi.org/10.1103/PRXQuantum.2.010325}{PRX QUANTUM 2 (2021) 010325}, a new way of investigating quantum gravity signatures using quantum information th…
`Seeing' the quantum ripples of spacetime
Soham Sen, Vlatko Vedral
We propose a novel way of detecting gravitons using emission of photons from charged array of quantum harmonic oscillators placed inside of a cavity while the cavity is being pumpe…
Gravity mediated entanglement of phonons in Bose-Einstein condensates
Soham Sen, Sunandan Gangopadhyay, Vlatko Vedral
The eigenstates of two test-masses (where each test-mass is placed inside of a harmonic trap) separated by a distance, can get entangled where gravity acts as the mediator of entan…
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).…
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…
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…
Uncertainty principle from the noise of gravitons
Soham Sen, Sunandan Gangopadhyay
The effect of the noise induced by gravitons in the case of a freely falling particle from the viewpoint of an external observer has been recently calculated in \href{https://link.…
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…
Lewis and Berry phases for a gravitational wave interacting with a quantum harmonic oscillator
Soham Sen, Manjari Dutta, Sunandan Gangopadhyay
In this work, we consider a gravitational wave interacting with a quantum harmonic oscillator in the transverse-traceless gauge. We take the gravitational wave to be carrying the s…
Signatures of quantum geometry from exponential corrections to the black hole entropy
Soham Sen, Ashis Saha, Sunandan Gangopadhyay
It has been recently shown in [Phys. Rev. Lett. 125 (2020) 041302] that microstate counting carried out for quantum states residing on the horizon of a black hole leads to a correc…
