Channel-selective magnetic filtering in a nodal-line semimetal
Hironmoy Pratihar, Alessandro De Martino, Arijit Kundu
We study quantum transport through a magnetic barrier in a nodal-line semimetal. When the Fermi energy lies near the nodal ring, the Fermi surface has toroidal geometry. Each cross…
Non-Bloch band theory of boundary-controlled magnon edge modes in an antiferromagnetic chain
Suman Debnath, Sonu Verma, Rohit Mukherjee +1
We define a winding number within the Non-Bloch band theory framework that captures the emergence of magnon edge modes in a one-dimensional antiferromagnetic spin chain, even when…
Skyrmion stripes in twisted double bilayer graphene
Debasmita Giri, Dibya Kanti Mukherjee, H. A. Fertig +1
Two dimensional moiré systems have recently emerged as a platform in which the interplay between topology and strong correlations of electrons play out in non-trivial ways. Among t…
Intrinsic nonlinear thermal Hall transport of magnons: A Quantum kinetic theory approach
Harsh Varshney, Rohit Mukherjee, Arijit Kundu +1
We present a systematic study of the nonlinear thermal Hall responses in bosonic systems using the quantum kinetic theory framework. We demonstrate the existence of an intrinsic no…
Operator correlations in a quenched non-Hermitian Luttinger liquid
Ashutosh Dubey, Sourav Biswas, Arijit Kundu
We study operator correlations of a spinful Luttinger liquid after introducing a non-Hermitian interaction quench, yielding supersonic modes and dominant superconducting correlatio…
Non-linear magnon transport in a bilayer van der Waals antiferromagnets
Rohit Mukherjee, Sonu Verma, Arijit Kundu
In this paper, we study the Berry curvature induced linear and nonlinear magnon transport in bilayer van der Waals antiferromagnets, where we deduce forms for the spin and energy c…
