physical significance is still the biggest open question because of its profound traits. In some …

'Quantum hairs' and entropy of the quantum isolated horizon from Chern–Simons theory

A Majhi, P Majumdar - Classical and Quantum Gravity, 2014 - iopscience.iop.org
We articulate the fact that the loop quantum gravity (LQG) description of the quantum
macrostates of black hole horizons, modeled as quantum isolated horizons (QIHs), is …

Loop quantum gravity: A demystified view

RP Vyas, MJ Joshi - Gravitation and Cosmology, 2022 - Springer
An attempt is made to demystify loop quantum gravity (LQG) in a concise and lucid way.
LQG is a background-independent as well as non-perturbative approach of the theory of …

[HTML][HTML] A possible quantum gravity hint in binary black hole merger

P Majumdar - Physics Letters B, 2024 - Elsevier
We present a semi-rigorous justification of Bekenstein's Generalized Second Law of
Thermodynamics applicable to a universe with black holes present, based on a generic …

First Steps to a Theory of Quantum Gravity

S Bilson-Thompson - Loop Quantum Gravity for the Bewildered: The Self …, 2024 - Springer
