abstract = {We propose helical topological superconductivity away from
the Fermi surface in three-dimensional
time-reversal-symmetric odd-parity multiband
superconductors. In these systems, pairing between electrons
originating from different bands is responsible for the
corresponding topological phase transition. Consequently, a
pair of helical topological Dirac surface states emerges at
finite excitation energies. These helical Dirac surface
states are tunable in energy by chemical potential and
strength of band splitting. They are protected by
time-reversal symmetry combined with crystalline twofold
rotation symmetry. We suggest concrete materials in which
this phenomenon could be observed.},
