Persistent nonlinear Hall effect driven by parallel field across a topological phase transition and intraband sign-reversing integer quantum Hall effect

Suheel Ahmad Malik, M. A. H. Ahsan, SK Firoz Islam

We investigate the linear and nonlinear Hall effects in a two-dimensional Rashba spin-orbit coupled nodal ring electronic system. We consider both the cases of linear Hall effect,…

Novel phases in rotating Bose-condensed gas: vortices and quantum correlation

Mohd. Imran, M. A. H. Ahsan

We present the exact diagonalization study of rotating Bose-condensed gas interacting via finite-range Gaussian potential confined in a quasi-2D harmonic trap. The system of many-b…

Multi-vortex Bose-Einstein condensate: examining the role of interaction range using Gaussian potential

Md Hamid, M A H Ahsan

We present exact diagonalization study on a system of spinless bosons interacting via repulsive Gaussian potential, harmonically confined in -plane with an…

Effects of discrete topology on quantum transport across a graphene junction: A quantum gravity analogue

Naveed Ahmad Shah, Alonso Contreras-Astorga, François Fillion-Gourdeau +3

In this article, we investigate the effect of next-to-the-nearest atom hopping on Klein tunnelling in graphene. An effective quantum dynamics equation is obtained based on an emerg…

Effect of van-Hove singularities in single-walled carbon nanotube leads on transport through double quantum dot system

Haroon, M. A. H. Ahsan

The double quantum dot system with single-walled metallic armchair carbon nanotube leads has been studied using Non-equilibrium Green function in the Keldysh formalism. The effect…
