Chiral topological superconductivity in twisted bilayer and double bilayer graphene
Kamalesh Bera, Tanay Nag, Arijit Saha
We present a theoretical investigation of the emergence of chiral topological superconductivity in small-angle twisted bilayer graphene (tBLG) and twisted double bilayer graphene (…
Field-free diode effects in one-dimensional superconductor: a complex interplay between Fulde-Ferrell pairing and altermagnetism
SVS Sai Ruthvik, Tanay Nag
We investigate the emergence of nonreciprocal dissipationless supercurrents in one-dimension manifested through the superconducting diode effect (SDE) and the Josephson diode effec…
Topological superconductivity and superconducting diode effect mediated via unconventional magnet and Ising spin-orbit coupling
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…
Generation of concurrence in a generalized central spin model with a three-spin interacting environment
Adithya A. Vasista, Anushka Agrawal, Tanay Nag
We consider the three-spin Ising model to study the effect of three-spin interacting term on bi-partitie entanglement between adjacent spins. The three-dominated disordered region…
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…
The orbital-driven topological phase transition and planar Hall responses in ternary tellurides Weyl semi-metals
Banasree Sadhukhan, Tanay Nag
We study electronic properties of the ternary tellurides TaXTe (X=Rh, Ir) using density functional theory and investigate chiral anomaly mediated planar Hall response from ab i…
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…
Josephson current signature of Floquet Majorana and topological accidental zero modes in altermagnet heterostructures
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…
Emergence of topological superconductivity in the presence of chiral magnetism in 2D CrInTe
Arnob Mukherjee, Fengyi Zhou, Soheil Ershadrad +3
We propose a general framework for designing a two-dimensional (2D) topological superconductor (TSC) using a magnet-superconductor hybrid system. This setup involves a monolayer of…
