Strong zero modes in random Ising-Majorana chains
Saurav Kantha, Nicolas Laflorencie
We investigate the fate and robustness of topological strong zero modes (SZMs) in random Ising-Majorana chains using the SZM fidelity, , as a many-body diagnost…

Fermion-Vortex Interactions in Axion Electrodynamics
Saurav Kantha, Amitabha Lahiri
A relativistic action for scalar condensate-fermion mixture is considered where both the scalar boson and the fermion fields are coupled to a gauge field. The dynamics of th…

Spin Injection Route to Magnon Berry Curvature Dipole
Atul Rathor, Saurav Kantha, Arijit Haldar
Berry curvature of Bloch bands arising in lattice systems can induce a Hall response even in the absence of topology due to the so-called Berry-curvature dipole (BCD). Such a respo…
