5. Quantum mechanical systems interacting with different polarizations of gravitational waves in noncommutative phase space / Saha, Anirban ; Gangopadhyay, Sunandan ; Saha, Swarup
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 their detection lies in the gravitational wave (GW) detection scenario, where one effectively probes the relative length-scale variations O[10201023].
