Vortex nucleation barriers and stable fractional vortices near boundaries in multicomponent superconductors
Andrea Maiani, Andrea Benfenati, Egor Babaev
The magnetization process of a superconductor is determined by the potential barrier for vortex nucleation and escape. In multicomponent superconductors, fractional vortices with a…

Spontaneous edge corner currents in superconductors and time reversal symmetry breaking surface states
Andrea Benfenati, Egor Babaev
We present a study of the basic microscopic model of an -wave superconductor with frustrated interband interaction. When frustration is strong, such an interaction gives raise t…
