Semi-classical Imprint of Horizon Induced Instability
Arnab Chakraborty, Onirban Islam, Arshad Momen
We consider an inverted harmonic oscillator in the space of square-integrable functions on the circle and compute its density of states employing…
Classicalization in Derivatively Coupled Scalar Field Theories: A Feasibility Study
Mishkat Al Alvi, Arshad Momen
It has been suggested that a certain class of UV-incomplete quantum field theories can avoid unitarity violation above the cut-off energy scale by forming classical configurations…
Equations of Motion as Covariant Gauss Law: The Maxwell-Chern-Simons Case
A. P. Balachandran, Arshad Momen, Amilcar R. de Queiroz
Time-independent gauge transformations are implemented in the canonical formalism by the Gauss law which is not covariant. The covariant form of Gauss law is conceptually important…
Spacetime Dimensionality from de Sitter Entropy
Arshad Momen, Rakibur Rahman
We argue that de Sitter universes with a small cosmological constant are entropically favored to have three spatial dimensions. The conclusion relies on the causal-patch descriptio…
A Comment on Curvature Effects In CFTs And The Cardy-Verlinde Formula
Arshad Momen, Tapobrata Sarkar
We examine the Cardy-Verlinde formula for finite temperature N=4 Super Yang-Mills theory on , and its AdS dual. We find that curvature effects introduce non-trivial co…
Quark-Antiquark Potential for Siegel Strings
Arshad Momen, G. Dastegir Al-Quaderi
We compute the quark-antiquark potential employing the continuum action for QCD-like random lattice strings proposed by Siegel. The model leads to a potential similar to those obta…
