"anisotropic two-fold symmetry... in-plane magnetic field direction... tunneling spectroscopy collect measurements revealed superconducting gap in atomically thin 2M-WS2 possesses anisotropic magnetic response along different in-plane magnetic field directions persists much above Pauli limit... strong spin-orbit-parity coupling arising from topological band inversion in 2M-WS2... pins spin of states near topological band crossing and renormalizes effect of external Zeeman fields anisotropically"
