Quantum mechanics in de Sitter space
Subir Ghosh, Salvatore Mignemi
We consider some possible phenomenological implications of the extended uncertainty principle, which is believed to hold for quantum mechanics in de Sitter spacetime. The relative…
Topics in Noncommutative Geometry Inspired Physics
Rabin Banerjee, Biswajit Chakraborty, Subir Ghosh +2
In this review article we discuss some of the applications of noncommutative geometry in physics that are of recent interest, such as noncommutative many-body systems, noncommutati…
Relativistic Thermodynamics with an Invariant Energy Scale
Sudipta Das, Subir Ghosh, Dibakar Roychowdhury
A particular framework for Quantum Gravity is the Doubly Special Relativity (DSR) formalism that introduces a new observer independent scale, the Planck energy. Our aim in this pap…
The E(2) Particle
Subir Ghosh, And Probir Pal
Recently it has been advocated [1] that for describing nature within the minimal symmetry requirement, certain subgroups of Lorentz group may play a fundamental role. One such grou…
Generalized particle dynamics in anti de Sitter spaces: A source for dark energy
Sudipta Das, Subir Ghosh, Jan-Willem van Holten +1
We consider the generalized particle dynamics, proposed by us, in brane world formalisms for an asymptotically anti de Sitter background. The present framework results in a new mod…
Generalized particle dynamics: modifying the motion of particles and branes
Sudipta Das, Subir Ghosh, Jan-Willem van Holten +1
We construct a generalized dynamics for particles moving in a symmetric space-time, i.e. a space-time admitting one or more Killing vectors. The generalization implies that the eff…
