Abstract

The energy levels of the fermions bound to the vortex are considered for vortices in the superfluid/superconducting systems which contain the symmetry protected plane of zeroes in the gap function in bulk. The Caroli-de Gennes–Matricon branches with different n approach zero energy level at pz → 0. The density of states of the bound fermions diverges at zero energy giving rise to the (Formula presented.) dependence of DoS in the polar phase of superfluid 3He rotating with the angular velocity Ω and to the (Formula presented.) dependence of DoS for superconductors in the (dxz + idyz)-wave pairing state.
