Nonlinear Schrödinger equation - Wikipedia
网页In theoretical physics, the (one-dimensional) nonlinear Schrödinger equation (NLSE) is a nonlinear variation of the Schrödinger equation. It is a classical field equation whose principal applications are to the propagation of light in nonlinear optical fibers and planar waveguides [ 2 ] and to Bose–Einstein condensates confined to highly ...
