Second-order Skin Effect in a Brick-Wall Lattice
Dipendu Halder, Srijata Lahiri, Saurabh Basu
Non-Hermitian skin effect, which is a unique feature of non-Hermitian systems, exhibits the formation of an extensive number of boundary modes under open boundary conditions. Howev…
Floquet Non-Bloch Formalism for a Non-Hermitian Ladder: From Theoretical Framework to Topolectrical Circuits
Koustav Roy, Dipendu Halder, Koustabh Gogoi +2
Periodically driven systems intertwined with non-Hermiticity opens a rich arena for topological phases that transcend conventional Hermitian limits. The physical significance of th…
Competing topological phases in a non-Hermitian time-reversal symmetry-broken Bernevig-Hughes-Zhang model
Dipendu Halder, Srijata Lahiri, Saurabh Basu
The Bernevig-Hughes-Zhang (BHZ) model, which serves as a cornerstone in the study of the quantum spin Hall insulators, showcases robust spin-filtered helical edge states in a nanor…
Circuit realisation of a two-orbital non-Hermitian tight-binding chain
Dipendu Halder, Ronny Thomale, Saurabh Basu
We examine a non-Hermitian (NH) tight-binding system comprising of two orbitals per unit cell and their electrical circuit analogues. We distinguish the PT-symmetric and non-PT sym…
Parsing skin effect in a non-Hermitian spinless BHZ-like model
Dipendu Halder, Saurabh Basu
This work comprehensively investigates the non-Hermitian skin effect (NHSE) in a spinless Bernevig- Hughes-Zhang (BHZ)-like model in one dimension. It is generally believed that a…
