The Undecidable Charge Gap and the Oil Drop Experiment
Abhishek Majhi
Decision problems in physics have been an active field of research for quite a few decades resulting in some interesting findings in recent years. However, such research investigat…
Unprovability of First Maxwell's Equation in Light of EPR's Completeness Condition -- A Computational Approach from Logico-linguistic Perspective
Abhishek Majhi
Maxwell's verbal statement of Coulomb's experimental verification of his hypothesis, concerning force between two electrified bodies, is suggestive of a modification of the respect…
Scientific value of the quantum tests of equivalence principle in light of Hilbert's sixth problem
Abhishek Majhi, Gopal Sardar
In his sixth problem, Hilbert called for an axiomatic approach to theoretical physics with an aim to achieve precision and rigour in scientific reasoning, where logic and language…
Cauchy's Logico-Linguistic Slip, the Heisenberg Uncertainty Principle and a Semantic Dilemma Concerning "Quantum Gravity"
Abhishek Majhi
The importance of language in physics has gained emphasis in recent times, on the one hand through Hilbert's views that concern formalism and intuition applied for outer inquiry, a…
Logic, Philosophy and Physics: a critical commentary on the dilemma of categories
Abhishek Majhi
I provide a critical commentary regarding the attitude of the logician and the philosopher towards the physicist and physics. The commentary is intended to showcase how a general c…
A logico-linguistic inquiry into the foundations of physics: Part I
Abhishek Majhi
Physical dimensions are {\it not numbers}, but used as {\it numbers} to perform dimensional analysis by the physicist. The law of excluded middle falls short of explaining the cont…
Variation of rest mass scale in a gravitational field
Abhishek Majhi
I argue that an angular momentum scale is necessary to explain energy-momentum propagation along a single null geodesic, the scale being known as Planck's constant . If an…
Note on isolated horizon
Abhishek Majhi
We point out that the symplectic structure, written in terms of the Sen-Ashtekar-Immirzi-Barbero variables, of a spacetime admitting an isolated horizon as the inner boundary, invo…
Singularity from star collapse, torsion and asymptotic safety of gravity
Abhishek Majhi
A star of mass greater than a critical mass is believed to undergo gravitational collapse to form a singularity, owing to Hawking-Penrose singularity theorem which is based on the…
An area rescaling ansatz and black hole entropy from loop quantum gravity
Abhishek Majhi
Considering the possibility of `renormalization' of the gravitational constant on the horizon, leading to a dependence on the level of the associated Chern-Simons theory, a rescale…
Expectation of primordial gravity waves generated during inflation
Gabriel León, Abhishek Majhi, Elias Okon +1
The inflationary paradigm is extremely successful regarding predictions of temperature anisotropies in the CMB. However, inflation also makes predictions for a CMB B-mode polarizat…
Non-extensive Statistical Mechanics and Black Hole Entropy From Quantum Geometry
Abhishek Majhi
Using non-extensive statistical mechanics, the Bekenstein-Hawking area law is obtained from microstates of black holes in loop quantum gravity, for arbitrary real positive values o…
Conformal blocks on a 2-sphere with indistinguishable punctures and implications on black hole entropy
Abhishek Majhi
The dimensionality of the Hilbert space of a Chern-Simons theory on a 3-fold, in the presence of Wilson lines carrying spin representations, had been counted by using its link with…
Proof of Bekenstein-Mukhanov ansatz in loop quantum gravity
Abhishek Majhi
A simple proof of Bekenstein-Mukhanov(BM) ansatz is given within the loop quantum gravity(LQG) framework. The macroscopic area of an equilibrium black hole horizon indeed manifests…
Field dynamics on the trapping horizon in Vaidya spacetime
Abhishek Majhi
In this article, we shed some light on the field theoretic aspect of the spherically symmetric trapping horizon in Vaidya spacetime. The effective field equations are that of a Che…
Reassessing the link between B-modes and inflation
Gabriel León, Abhishek Majhi, Elias Okon +1
We reevaluate the predictions of inflation regarding primordial gravity waves, which should appear as B-modes in the CMB, in light of the fact that the standard inflationary paradi…
Black Hole Entropy from indistinguishable quantum geometric excitations
Abhishek Majhi
In loop quantum gravity, the quantum geometry of a black hole horizon consist of discrete non-perturbative quantum geometric excitations (or punctures) labeled by spins, which are…
Thermodynamic partition function from quantum theory for black hole horizons in loop quantum gravity
Abhishek Majhi
We establish the link between the thermodynamics and the quantum theory of black hole horizons through the construction of the thermodynamic partition function, partly based on som…
Energy spectrum of black holes : a new view
Abhishek Majhi
Energy of a black hole is usually quantized by invoking some area quantization scheme after expressing the energy in terms of the horizon area. However, in this approach one has to…
