Abstract: Abstract We consider self-focusing nonlinear optical crystal separated by linear dielectric plate. The nonlinear crystals are characterized by an abruptly changing dielectric permittivity and Kerr nonlinearity coefficients in dependence on electric field amplitude. Two new… read more here.

Abstract: We propose a theory of nonlinear surface resistance of a dirty superconductor in a strong radio-frequency (RF) field, taking into account magnetic and nonmagnetic impurities, finite quasiparticle lifetimes, and a thin proximity-coupled normal layer characteristic… read more here.
