Noncommutative Landau problem in graphene: a gauge-invariant analysis with the Seiberg-Witten map
Aslam Halder
We investigate the relativistic quantum dynamics of amassless electron in graphene in a two-dimensional noncommutative (NC) plane under a constant background magnetic field. To add…
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…
Phase transitions in Born-Infeld AdS black holes in D-dimensions
Neeraj Kumar, Sukanta Bhattacharyya, Sunandan Gangopadhyay
In this paper, we have investigated phase transitions in arbitrary spacetime dimensions for Born-Infeld AdS black holes. The phase transition points are characterised from the dive…
Holographic free energy and thermodynamic geometry
Debabrata Ghorai, Sunandan Gangopadhyay
We analytically obtain the free energy and thermodynamic geometry of holographic superconductors in -dimensions. The gravitational theory in the bulk dual to this -dimens…
Response of simple quantum systems to different polarizations of gravitational waves in noncommutative phase-space
Sunandan Gangopadhyay, Anirban Saha, Swarup Saha
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 t…
Noncommutative effects of spacetime on holographic superconductors
Debabrata Ghorai, Sunandan Gangopadhyay
The Sturm-Liouville eigenvalue method is employed to analytically investigate the properties of holographic superconductors in higher dimensions in the framework of Born-Infeld ele…
