Intriguing topological superconductor phases in long-range extended Kitaev models: an interplay between sub-lattices and power-law interaction
Dharana Joshi, Amaan Khan, Tanay Nag
The power-law profile of hopping and superconductivity introduces rich critical phenomena that are not possible to explore in the nearest-neighbor models. Having this in mind, we c…
Localization and Transport in a Non-Hermitian Hexagonal Harper Model
Akshey Rajoriya, Dibyajyoti Sahu, Suhas Gangadharaiah +1
We investigate a one-dimensional non-Hermitian hexagonal Harper model with quasiperiodically modulated hopping amplitudes. In the Hermitian limit, the model exhibits metallic, insu…
Topological Hall plateau in quasi-2D kagome magnet YMnSn
Sambit Jena, Nastaran Salehi, Manuel Pereiro Lopez +5
We examine the impact of the Dzyaloshinskii--Moriya interaction (DMI) in kagome magnets and show that a predominantly planar DMI together with ferromagnetic exchange stabilizes a d…
Spin-orbit coupling driven topological superconductivity in twisted bilayer graphene-WSe heterostructures
Kamalesh Bera, Arijit Saha, Tanay Nag
Commencing from the low-energy Bistritzer-MacDonald continuum model of twisted bi-layer graphene (tBLG) with proximity-induced Ising, Rashba, and intrinsic spin-orbit couplings (SO…
Superconducting diode effect via Floquet topological Fulde-Ferrell phase in driven Rashba nanowire
Sayak Bhowmik, Arijit Saha, Tanay Nag
Much has been studied on Floquet engineering in Rashba nanowire model regarding topological superconductivity hosting Majorana - and anomalous -modes, here we theoretically i…
Quantized orbital and spin Hall transport: interplay between -hybridization, altermagnetism and spin-orbit coupling
Saikat Saha, Banasree Sadhukhan, Tanay Nag
We here explore the emergence of orbital and spin Hall effects, originating beyond the - coupling, and investigate the interplay between inter-orbit hybridization, relativist…
Finite-size scaling properties of classical random walk on various two-dimensional lattices
Nimish Sharma, Tanay Nag
We consider various two-dimensional lattices such as square, Kagome, Lieb, honeycomb, dice lattices of finite extent, to study the effect of lattice profile in terms of the number…
Semiclassical theory of frequency dependent linear magneto-optical transport in Weyl semimetals
Azaz Ahmad, Pankaj Bhalla, Snehasish Nandy +1
We develop a semiclassical Boltzmann theory for frequency-dependent magneto-optical transport in Weyl semimetals (WSMs), incorporating momentum-dependent relaxation via a scatterin…
