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…
Constraints on superconducting pairing in altermagnets
Debmalya Chakraborty, Annica M. Black-Schaffer
Superconductivity in the recently discovered altermagnetic materials hosts large prospects for both fundamental physics and technological applications. In this work we show that a…
Enhanced quantum metric due to vacancies in graphene
Quentin Marsal, Annica M. Black-Schaffer
Random vacancies in a graphene monolayer induce defect states that are known to form a narrow impurity band centered around zero energy at half-filling. We use a space-resolved for…
Enhanced chiral edge currents and orbital magnetic moment in chiral -wave superconductors from mesoscopic finite-size effects
Patric Holmvall, Annica M. Black-Schaffer
Chiral superconductors spontaneously break time-reversal symmetry and host topologically protected edge modes, supposedly generating chiral edge currents which are typically taken…
Robust topological superconductivity in weakly coupled nanowire-superconductor hybrid structures
Oladunjoye A. Awoga, Jorge Cayao, Annica M. Black-Schaffer
We investigate the role of the coupling between a spin-orbit coupled semiconductor nanowire and a conventional -wave superconductor on the emergence of the topological supercond…
From chiral d-wave to nodal line superconductivity in the harmonic honeycomb lattices
Johann Schmidt, Adrien Bouhon, Annica Black-Schaffer
Motivated by the recent realization of the three-dimensional hyperhoneycomb and stripyhoneycomb lattices in lithium iridate (LiIrO), we study the possible spin-singlet supe…
