Observation of Highly Efficient Electric-Quadrupole Second Harmonic Generation in a Dirac Semimetal
Abstract Topological semimetals hold great promise for nonlinear optics (NLO). It is challenging to probe tilted Dirac fermion-driven intrinsic second harmonic generation (SHG) and topological band structure modulation of second-order nonlinearity in spatial inversion and time-re...
