Emergence of a new symmetry class for Bogoliubov-de Gennes (BdG) Hamiltonians: Expanding ten-fold symmetry classes
Ranjith Kumar R, Sujit Sarkar
Symmetry plays an important role in the topological states of quantum matter. Cartan found three symmetry classes, Altland and Zirnbauer extended it to the ten-fold symmetry class…
A Study of Curvature Theory for Different Symmetry Classes of Hamiltonian
Y R Kartik, Ranjith R Kumar, S Rahul +1
We study and present the results of curvature for different symmetry classes (BDI, AIII and A) model Hamiltonians and also present the transformation of model Hamiltonian from one…
Quantum Berezinskii-Kosterltz-Thouless Transition for Topological Insulator
Ranjith Kumar R, Rahul S, Surya Narayan +1
We consider the interacting helical liquid system at the one-dimensional edge of a two-dimensional topological insulator, coupled to an external magnetic field and s-wave supercond…
An Interplay of Topology and Quantized Geometric Phase for two Different Symmetry-Class Hamiltonians
Rahul S, Ranjith Kumar R, Y R Kartik +2
Study of symmetry, topology and geometric phase can reveal many new and interesting results on the topological states of matter. Here we present a completely new and interesting re…
A Study of Asymptotic Freedom like Behavior for Topological States of Matter
Ranjith Kumar R, Rahul S, Surya Narayan +1
We present results for asymptotic freedom like behavior for the topological state of the helical spin liquid system with finite proximity induced superconducting gap. We derive two…
