Chiral, parity-doublet, effective-Lagrangian mean-field theories for nuclear and astrophysical phenomenology
Ayon Mukherjee
Chiral-parity (parity-doublet) effective Lagrangian models provide a compact and symmetry-consistent framework for describing baryons and their negative-parity partners in terms of…
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…
First integrals of some two-dimensional integrable Hamiltonian systems
Aritra Ghosh, Akash Sinha, Bijan Bagchi
In this paper, we discuss some results on integrable Hamiltonian systems with two degrees of freedom. We revisit the much-studied problem of the two-dimensional harmonic oscillator…
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…
Resonant detectors of gravitational wave in the linear and quadratic generalized uncertainty principle framework
Sukanta Bhattacharyya, Soham Sen, Sunandan Gangopadhyay
In this work, we consider a resonant bar detector of gravitational wave in the generalized uncertainty principle (GUP) framework with linear and quadratic momentum uncertainties. T…
Study of Einstein Equivalence Principle with Sagnac Effect in Lorentz and Galilean Frame
Shouvik Sadhukhan
Sagnac effect has been studied in terms of Gyroscopic system in both Lorentz frame as well as flat Einstein frame. The Einstein equivalence principle has been used to determine the…
