Large nonlinear Hall effect in strained moiré structures hosting pseudospin-3/2 fermions
Srijata Lahiri, Gourab Paul, Bilal Tanatar +1
We investigate the linear and nonlinear Hall response of a moiré \emph{watermill lattice}, in which stacking and twisting generate a four-band manifold near the Fermi level with su…
Probing topological phase transitions via nonlinear Hall response in strained moiré dice lattice
Gourab Paul, Srijata Lahiri, Bilal Tanatar +1
Valley polarized twisted bilayer dice lattice hosts topologically nontrivial flat bands far from charge neutrality due to broken time reversal symmetry, whereas the ones in the vic…
Emergence of Non-Hermitian Magic Angles and Topological Phase Transitions in Twisted Bilayer - Lattices
Shaina Gandhi, Gourab Paul, Srijata Lahiri +1
We investigate the flat-band properties and topological phase transitions in a non-Hermitian twisted bilayer lattice. Here, non-Hermiticity is introduced via Hatano-Nelson-…
Emergent topology of flat bands in a twisted bilayer - lattice
Gourab Paul, Srijata Lahiri, Kuntal Bhattacharyya +1
We investigate an interesting interplay of destructive interference due to lattice geometry and band folding due to enlargement of the Brillouin zone in generating and subsequently…
Floquet-engineered diode performance in a Majorana-quantum dot Josephson junction
Koustav Roy, Gourab Paul, Debika Debnath +2
We study nonreciprocal signatures of Josephson current (JC) in a quantum dot (QD)-based Josephson junction (JJ) that comprises of two periodically driven Kitaev chains (KCs) couple…
