Applied Mathematics and Computation Seminar
The Discrete Cubic-Quintic Nonlinear Schrodinger Equation
Chris Chong , University of Karlsruhe

We study the existence and stability of fundamental discrete solitons in one-, two- and three-dimensional nonlinear Schr"odinger lattices with a combination of cubic self-focusing and quintic self-defocusing onsite nonlinearities. Several species of stationary solutions are constructed, and bifurcations linking their families are investigated.
