Minimal Length and the Existence of Some Infinitesimal Quantities in Quantum Theory and Gravity [PDF]

open access: yes, 2014
In this work it is demonstrated that, provided a theory involves a minimal length, this theory must be free from such infinitesimal quantities as infinitely small variations in surface of the holographic screen, its volume, and entropy. The corresponding

Gauge Interaction as Periodicity Modulation

open access: yes, 2012
The paper is devoted to a geometrical interpretation of gauge invariance in terms of the formalism of field theory in compact space-time dimensions [arXiv:0903.3680].

Note on a new fundamental length scale $l$ instead of the Newtonian constant $G$

open access: yes, 2011
The newly proposed entropic gravity suggests gravity as an emergent force rather than a fundamental one. In this approach, the Newtonian constant $G$ does not play a fundamental role any more, and a new fundamental constant is required to replace its ...

Quantum Aspects of Black Hole Entropy [PDF]

open access: yes, 2000
This survey intends to cover recent approaches to black hole entropy which attempt to go beyond the standard semiclassical perspective. Quantum corrections to the semiclassical Bekenstein-Hawking area law for black hole entropy, obtained within the ...

Background independent holographic dual to $T\bar{T}$ deformed CFT with large central charge in 2 dimensions

open access: yes, 2017
The geometerization of the renormalization group flow triggered by the $T\bar{T}$ deformation of large $c$ conformal field theories in two dimensions is presented. This entails the construction of the off shell Einstein-Hilbert action in three dimensions

Torsional Newton-Cartan Geometry and the Schr\"odinger Algebra [PDF]

open access: yes, 2014
We show that by gauging the Schr\"odinger algebra with critical exponent $z$ and imposing suitable curvature constraints, that make diffeomorphisms equivalent to time and space translations, one obtains a geometric structure known as (twistless ...

Elementary spacetime cycles

open access: yes, 2013
Every system in physics is described in terms of interacting elementary particles characterized by modulated spacetime recurrences. These intrinsic periodicities, implicit in undulatory mechanics, imply that every free particle is a reference clock ...

Hypersurface foliation approach to renormalization of ADM formulation of gravity [PDF]

open access: yes, 2015
We carry out ADM splitting in the Lagrangian formulation and establish a procedure in which (almost) all of the unphysical components of the metric are removed by using the 4D diffeomorphism and the measure-zero 3D symmetry.

Holographic multiverse and the measure problem

open access: yes, 2011
We discuss the duality, conjectured in earlier work, between the wave function of the multiverse and a 3D Euclidean theory on the future boundary of spacetime.

A conjecture on the origin of dark energy

open access: yes, 2011
The physical origin of holographic dark energy (HDE) is investigated. The main existing explanations, namely the UV/IR connection argument of Cohen et al, Thomas' bulk holography argument, and Ng's spacetime foam argument, are shown to be not ...
