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…
Quantum gravitational deflection of parallel matter wave beams
Soham Sen, Vlatko Vedral
It is well known that two parallel photon beams do not deflect under the effect of their energy-momentum tensor. In this work, we propose a novel model where two spatially separate…
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…
Signatures of Quantum Gravity In Relativistic Quantum Systems
Soham Sen
In this thesis, we have used a linearized quantum gravity setting to investigate the effects of gravitons on matter systems. Based on the graviton-matter interaction, we have then…
Detecting gravitational waves by emission of photons from charged Weber bars
Soham Sen
In this work, we propose a novel experimental set-up using charged resonant gravitational wave detectors. We exploit the semi-classical analogue of the Gertsenshtein effect where t…
