Impurity strength-temperature phase diagram with phase crystals and competing time-reversal symmetry breaking states in nodal -wave superconductors
Kevin Marc Seja, Niclas Wall-Wennerdal, Tomas Löfwander +3
Phase crystals are a class of nonuniform superconducting ground states characterized by spontaneous phase gradients of the superconducting order parameter. These phase gradients no…

Spontaneous splitting of d-wave surface states: Circulating currents or edge magnetization?
Kevin Marc Seja, Niclas Wall-Wennerdal, Tomas Löfwander +1
Pair-breaking edges of -wave superconductors feature Andreev bound states at the Fermi energy. Since these states are energetically highly unfavorable they are susceptible to ef…

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…
