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).…
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…
