Manipulation of Majorana wave packets at surfaces of nodal noncentrosymmetric superconductors
Clara J. Lapp, Julia M. Link, Carsten Timm
Nodal noncentrosymmetric superconductors can host zero-energy flat bands of Majorana surface states within the projection of the nodal lines onto the surface Brillouin zone. Thus,…
Complete zero-energy flat bands of surface states in fully gapped chiral noncentrosymmetric superconductors
Clara J. Lapp, Julia M. Link, Carsten Timm
Noncentrosymmetric superconductors can support flat bands of zero-energy surface states in part of their surface Brillouin zone. This requires that they obey time-reversal symmetry…
Bogoliubov Fermi surfaces stabilized by spin-orbit coupling
Henri Menke, C. Timm, P. M. R. Brydon
It was recently understood that centrosymmetric multiband superconductors that break time-reversal symmetry generically show Fermi surfaces of Bogoliubov quasiparticles. We investi…
Bogoliubov Fermi surfaces in superconductors with broken time-reversal symmetry
D. F. Agterberg, P. M. R. Brydon, C. Timm
It is commonly believed that in the absence of disorder or an external magnetic field, there are three possible types of superconducting excitation gaps: the gap is nodeless, it ha…
