Query: Theory of inverse Faraday effect in disordered metal in THz regime   We calculate the magnetization dynamics induced by the inverse Faraday effect
in disordered metals in THz regime by using the diagrammatic method. We find
that the induced magnetization is proportional to the frequency of circularly
polarized light.
