Topological states of multiband superconductors with interband pairing
M. F. Holst, M. Sigrist, K. V. Samokhin
We study the effects of interband pairing in two-band s-wave and d-wave superconductors with D4h symmetry in both time-reversal invariant as well as time-reversal symmetry breaking…
Fermionic boundary modes in two-dimensional noncentrosymmetric superconductors
K. V. Samokhin, S. P. Mukherjee
We calculate the spectrum of the Andreev boundary modes in a two-dimensional superconductor formed at an interface between two different non-superconducting materials, e.g. insulat…
Quasiparticles near domain walls in hexagonal superconductors
S. P. Mukherjee, K. V. Samokhin
We calculate the energy spectrum of quasiparticles trapped by a domain wall separating different time reversal symmetry-breaking ground states in a hexagonal superconductor, such a…
Domain walls in superconductors: Andreev bound states and tunneling features
S. P. Mukherjee, K. V. Samokhin
Domain walls can be formed in superconductors with a discrete degeneracy of the ground state, for instance, due to the breaking of time reversal symmetry. We study all cases where…
Helical states and solitons in noncentrosymmetric superconductors
K. V. Samokhin
We show how the two-band nature of superconductivity in noncentrosymmetric compounds leads to a variety of novel nonuniform superconducting states induced by a magnetic field. At l…
Phase solitons and subgap excitations in two-band superconductors
K. V. Samokhin
A phase soliton is a topological defect peculiar to two-band superconductors, which is associated with a winding of the relative phase of the two superconducting condensates.…
