Large nonlinear Hall effect in strained moiré structures hosting high-pseudospin 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…
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…
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…
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…
