Footprint of spatial noncommutativity in resonant detectors of gravitational wave

S Bhattacharyya, S Gangopadhyay… - Classical and Quantum …, 2019 - iopscience.iop.org
The present day gravitational wave (GW) detectors strive to detect the length variation,
which, owing to the smallness of the metric perturbation∼ h, is an extremely small length …

Gravitational collapse of a homogeneous scalar field in deformed phase space

SMM Rasouli, AH Ziaie, J Marto, PV Moniz - Physical Review D, 2014 - APS
We study the gravitational collapse of a homogeneous scalar field, minimally coupled to
gravity, in the presence of a particular type of dynamical deformation between the canonical …

Quantum mechanical systems interacting with different polarizations of gravitational waves in noncommutative phase space

A Saha, S Gangopadhyay, S Saha - Physical Review D, 2018 - APS
Owing to the extreme smallness of any noncommutative scale that may exist in nature, both
in the spatial and momentum sector of the quantum phase space, a credible possibility of …

Resonant detectors of gravitational wave as a possible probe of the noncommutative structure of space

A Saha, S Gangopadhyay - Classical and Quantum Gravity, 2016 - iopscience.iop.org
We report the plausibility of using quantum mechanical transitions, induced by the combined
effect of gravitational waves (GWs) and noncommutative (NC) structure of space, among the …

[HTML][HTML] On the Landau system in noncommutative phase-space

S Gangopadhyay, A Saha, A Halder - Physics Letters A, 2015 - Elsevier

We study space-time noncommutativity applied to the hydrogen atom and its
phenomenological effects. We find that it modifies the potential part of the Hamiltonian in …

Thermodynamics of a charged particle in a noncommutative plane in a background magnetic field

A Halder, S Gangopadhyay - International Journal of Theoretical Physics, 2017 - Springer
