Nonlinear optical absorption and photocurrents in topological insulators
Theory of optical absorption of linearly and circularly polarized light in surface and edge states in topological insulators is developed for a nonlinear light intensity regime. The absorbance for surface states and the absorption width for the edge states both decrease as 1/I at high light intensit...
