Stimulated Hawking Emission From Electromagnetic Analogue Black Hole: Theory and Observation
Avijit Bera, Subir Ghosh
In this paper we consider possible analogue Hawking radiation from a normal dielectric and metamaterial composite, having an analogue horizon where the dielectric parameters vanish…
Note on Morita Inequality for Planar Noncommutative Inverted Oscillator
Praloy Das, Subir Ghosh
A recent conjecture of Morita predicts a lower bound in temperature of a chaotic system, , being the Lyapunov exponent, which was demonstrated for a one…
Duality Between Dirac Fermions in Curved Spacetime and Optical solitons in Non-Linear Schrodinger Model: Magic of -Dimensional Bosonization
Subir Ghosh
Bosonization in curved spacetime maps massive Thirring model (self-interacting Dirac fermions) to a generalized sine-Gordon model, both living in -dimensional curved spacetime…
Relativistic Anyon Beam: Construction and Properties
Joydeep Majhi, Subir Ghosh, Santanu K. Maiti
Motivated by recent interest in photon and electron vortex beams, we propose the construction of a relativistic anyon beam. Following Jackiw and Nair [Phys. Rev. D 43, 1933 (1991)]…
Thermodynamics and Phase Transition in Shapere-Wilczek {\it fgh} model: Cosmological Time Crystal in Quadratic Gravity
Praloy Das, Supriya Pan, Subir Ghosh
The Shapere-Wilczek model \cite{wil}, or so called model, enjoys the remarkable features of a Time Crystal (TC) that has a non-trivial time dependence in its lowest energy s…
Quasinormal mode spectra for odd parity perturbations in spacetimes with smeared matter sources
Kumar Das, Souvik Pramanik, Subir Ghosh
We have found the Quasi Normal Mode (QNM) frequencies of a class of static spherically symmetric spacetimes having a {\it {smeared}} matter distribution, parameterized by - an…
