Holographic computation of Wilson loops in a background with broken conformal invariance and finite chemical potential
Ashis Saha, Sunandan Gangopadhyay
In this paper, we follow a `bottom-up' AdS/QCD approach to holographically probe the dynamics of a moving pair inside a strongly coupled plasma at the boundary. We consi…
Dynamics Near An Idempotent
Md Moid Shaikh, Sourav Kanti Patra
Hindman and Leader first introduced the notion of semigroup of ultrafilters converging to zero for a dense subsemigroups of . Using the algebraic structure of the S…
On the position dependent effective mass Hamiltonian
Kalpana Biswas, Jyoti Prasad Saha, Pinaki Patra
Noncommutivity of position and momentum makes it difficult to formulate the unambiguous structure of the kinetic part of Hamiltonian for the position-dependent effective mass (PDEM…
Shadow of charged black holes in Gauss-Bonnet gravity
Anish Das, Ashis Saha, Sunandan Gangopadhyay
In this paper, we investigate the effect of higher curvature corrections from Gauss-Bonnet gravity on the shadow of charged black holes in both and Minkowski spacetimes. The…
Spin-selective Aharonov-Casher caging in a topological quantum network
Amrita Mukherjee, Rudolf A. Romer, Arunava Chakrabarti
A periodic network of connected rhombii, mimicking a spintronic device, is shown to exhibit an intriguing spin selective extreme localization, when submerged in a uniform out of pl…
Holographic entanglement entropy and generalized entanglement temperature
Ashis Saha, Sunandan Gangopadhyay, Jyoti Prasad Saha
In this work we study the flow of holographic entanglement entropy in dimensions in the gauge/gravity duality set up. We observe that a generalized entanglement temperat…
