Abstract
We show that an in-plane Zeeman field applied to non-centrosymmetric Ising superconductors converts singlet -wave Cooper pairs to equal-spin triplet pairs, leading to an enhancement of the critical transition line beyond expected from Ising spin-orbit coupling. Singlet to triplet conversion relates to a phase transformation due to spin rotation by the Zeeman field and has a geometric origin. The discussion is especially relevant, but not limited to monolayer transition metal dichalcogenides.
