Perfect superconducting diode effect in altermagnets
Debmalya Chakraborty, Annica M. Black-Schaffer
We investigate intrinsic superconducting diode effect in the unconventional superconducting state of -wave altermagnets. We find large diode efficiencies in the wide-reaching fi…

Interaction-driven first-order and higher-order topological superconductivity
Pietro M. Bonetti, Debmalya Chakraborty, Xianxin Wu +1
We investigate topological superconductivity in the Rashba-Hubbard model, describing heavy-atom superlattice and van der Waals materials with broken inversion. We focus in particul…
