Magnetic field dependence of the superconducting gap node topology in non-centrosymmetric CePt${}_3$Si

I. Eremin, J. F. Annett

The non-centrosymmetric superconductor CePt${}_3$Si is believed to have a line node in the energy gap arising from coexistence of s-wave and p-wave pairing. We show that a weak c-axi…
