Multi higher-order Dirac and nodal line semimetals
Amartya Pal, Arnob Kumar Ghosh
In recent years, there has been a surge of interest in exploring higher-order topology and their semi-metallic counterparts, particularly in the context of Dirac, Weyl, and nodal l…
Local and energy-resolved topological invariants for Floquet systems
Arnob Kumar Ghosh, Rodrigo Arouca, Annica M. Black-Schaffer
Periodically driven systems offer a perfect breeding ground for out-of-equilibrium engineering of topological boundary states at zero energy (-mode), as well as finite energy ($…
Corner modes in non-Hermitian next-nearest-neighbor hopping model
Arnob Kumar Ghosh, Arijit Saha, Tanay Nag
We consider a non-Hermitian (NH) analog of a second-order topological insulator, protected by chiral symmetry, in the presence of next-nearest neighbor hopping elements to theoreti…
Majorana zero-modes in a dissipative Rashba nanowire
Arnob Kumar Ghosh, Annica M. Black-Schaffer
Condensed matter systems are continuously subjected to dissipation, which often has adverse effects on quantum phenomena. We focus on the impact of dissipation on a superconducting…
