Difference frequency generation in topological semimetals
When two lasers are applied to a noncentrosymmetric material, it can generate light at the difference of the incoming frequencies Δω, a phenomenon known as difference frequency generation (DFG), well characterized in semiconductors. In this work, we derive a general expression for DFG in metals, whi...
