Fri, 14 Apr 2017 17:47:23 +0000http://datavoreconsulting.com/blog/?p=250#comment-12129Could you help me (OR i want a code) to find the numerical solution of the following nonlinear Schrödinger equation using finite difference method
i(du/dt)+(1/2)P(d²u/dx²)+Q|u|²u=0, x:[-L,L]
we can put P=0.137 and Q=4.54.
The initial solution is
u(x,t)=Sqrt(P/Q)*[-1+4(1+2iPt)/(1+4x²+4P²t²))]exp(iPt).
The following Dirichlet boundary conditions are used
u(-L,t)=u(L,t).

i(??/?t)+(1/2)P(?²?/?x²)+Q|?|²?=0, x?[-L,L]
we can put P=0.137 and Q=4.54.
The initial solution is
?(x,t)=?(P/Q)*[-1+4(1+2iPt)/(1+4x²+4P²t²))]exp(iPt).
The following Dirichlet boundary conditions are used
?(-L,?)=?(L,?).
