A Family of Non-commutative geometries
Debabrata Sinha, Pulak Ranjan Giri
It is shown that the non-commutativity in quantum Hall system may get modified. The self-adjoint extension of the corresponding Hamiltonian leads to a family of non-commutative geo…
Black Hole Entropy: From Shannon to Bekenstein
Subir Ghosh
In this note we have applied directly the Shannon formula for information theory entropy to derive the Black Hole (Bekenstein-Hawking) entropy. Our analysis is semi-classical in na…
Towards a Discrete Spacetime
Sudipta Das, Subir Ghosh
A formalism is proposed to generate (the first step of) a discrete spacetime: spacetime with an inbuilt length scale. We follow the celebrated Landau theory of liquid - solid phase…
Noncommutative Spacetime in Very Special Relativity
Sudipta Das, Subir Ghosh, Salvatore Mignemi
Very Special Relativity (VSR) framework, proposed by Cohen and Glashow [1], demonstrated that a proper subgroup of the Poincaré group, (in particular ISIM(2)), is sufficient to des…
Planck Scale Effect in the Entropic Force Law
Subir Ghosh
In this note we generalize the quantum uncertainty relation proposed by Vancea and Santos [7] in the entropic force law, by introducing Planck scale modifications. The latter is in…
Thermodynamics of Photon Gas with an Invariant Energy Scale
Sudipta Das, Dibakar Roychowdhury
Quantum Gravity framework motivates us to find new theories in which an observer independent finite energy upper bound (preferably Planck Energy) exists. We have studied the modifi…
