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…
