Floquet first- and higher-order topological superconductors: A review
Debashish Mondal, Arnob Kumar Ghosh, Arijit Saha +1
The current developments in quantum technologies are deeply rooted in quantum computation, with Majorana fermions and their topological protection expected to play a central role.…

Amartya Pal, Debashish Mondal, Tanay Nag +1
We propose a theoretical framework in which a one-dimensional (1D) tight-binding model incorporating unconventional magnetic order together with Rashba and Ising spin-orbit couplin…
Adiabatic charge transport through non-Bloch bands
Dharana Joshi, Tanay Nag
We explore the non-reciprocal intracell hopping mediated non-Hermitian topological phases of an extended Su-Schrieffer-Heeger model hosting second-nearest-neighbour hopping. We mic…
Topological energy pumping in a quasi-periodically driven four-level system
Vansh Kaushik, Sayan Choudhury, Tanay Nag
We investigate a quasi-periodically driven four-level system that serves as a temporal analog of topological phenomena found in four-band models with intertwined spin and orbital d…
Dissipation induced Majarona - and -modes in a driven Rashba nanowire
Koustabh Gogoi, Tanay Nag, Arnob Kumar Ghosh
Periodic drive is an intriguing way of creating topological phases in a non-topological setup. However, most systems are often studied as a closed system, despite being always in c…

Amartya Pal, Debashish Mondal, Tanay Nag +1
We theoretically investigate the generation and Josephson current signatures of Floquet Majorana end modes (FMEMs) in a periodically driven altermagnet (AM) heterostructure. Consid…
Extended Haldane model -- a modern gateway to topological insulators
Tanay Nag, Saptarshi Mandal
The seminal Haldane model brings up a paradigm beyond the quantum Hall effect to look for a plethora of topological phases in the honeycomb and other lattices. Here we dwell into t…
Adiabatic charge transport in extended SSH models
Dharana Joshi, Tanay Nag
We explore the topological properties of extended SSH models, considering four sub-lattices in a unit cell and second-nearest-neighbor intercell hopping for SSH4 and SSH long-range…

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…

Topological insulators~(TIs) are a new class of materials that resemble ordinary band insulators in terms of a bulk band gap but exhibit protected metallic states on their boundari…
Floquet second-order topological Anderson insulator hosting corner localized modes
Arnob Kumar Ghosh, Tanay Nag, Arijit Saha
The presence of random disorder in a metallic system accounts for the localization of extended states in general. On the contrary, the presence of disorder can induce topological p…
