Abstract:We show that Weyl superconductivity can be induced by finite supercurrent in noncentrosymmetric spin-orbitcoupled superconductors with line nodes. We introduce a three-dimensional tight-binding model of a tetragonal superconductor in a π· + π-wave pairing state with a finite center-of-mass momentum, and elucidate that a line-nodal to point-nodal spectral transition occurs by applying an infinitesimal supercurrent. We also clarify that the higher-order effect in spin-orbit coupling is particularly important fo… Show more
