Field-free superconducting diode effect in two-dimensional Shiba lattices
Sayak Bhowmik, Dibyendu Samanta, Ashis K. Nandy +2
The superconducting diode effect (SDE) refers to non-reciprocal transport, where current flows without resistance in one direction but becomes resistive in the opposite direction,…

Topological Majorana zero modes and the superconducting diode effect driven by Fulde-Ferrell-Larkin-Ovchinnikov pairing in a helical Shiba chain
Sayak Bhowmik, Arijit Saha
We propose a theoretical framework for the realization of Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) pairing in a helical Shiba chain subjected to an out-of-plane Zeeman field, analyz…
