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…
