Zero-field finite-momentum and field-induced superconductivity in altermagnets
Debmalya Chakraborty, Annica M. Black-Schaffer
We explore the possibilities for spin-singlet superconductivity in newly discovered altermagnets. Investigating -wave altermagnets, we show that finite-momentum superconductivit…
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…
Nonlocality of Majorana bound states revealed by electron waiting times in a topological Andreev interferometer
Paramita Dutta, Jorge Cayao, Annica M. Black-Schaffer +1
The analysis of waiting times of electron transfers has recently become experimentally accessible owing to advances in noninvasive probes working in the short-time regime. We study…
Superconductivity and magnetism in the surface states of ABC-stacked multilayer graphene
Oladunjoye A. Awoga, Tomas Löthman, Annica M. Black-Schaffer
ABC-stacked multilayer graphene (ABC-MLG) exhibits topological surface flat bands with a divergent density of states, leading to many-body instabilities at charge neutrality. Here,…
Fano resonances for tilted linear and quadratic band touching dispersions in a harmonically driven potential well
Anton Gregefalk, Annica Black-Schaffer, Tanay Nag
Considering models with tilted linear and quadratic band touching dispersions, we analyze the effect of the transverse linear tilt on the transmission spectra through a harmonicall…
Robust and tunable coreless vortices and fractional vortices in chiral -wave superconductors
Patric Holmvall, Niclas Wall-Wennerdal, Annica M. Black-Schaffer
Chiral -wave superconductivity has recently been proposed in a wide range of materials based on both experiment and theoretical works. Chiral superconductors host a finite Chern…
