Together with my adviser Prof. Dr. Wolfgang Reichel I investigate nonlinear wave equations for timeperiodic solutions. A prototype is
The equation is physically motivated by nonlinear polarisation effects. In particular I look at a polarisation of the form .
My main tool is the calculus of variations. Its basic idea is the fact that some solutions of differential equations are minimizers of suitable functionals. Such solutions are often calles ground states. These are of special physical interest. In addition I use the concept of truncated Fourier series to generate aproximative solutions. These (hopefully) converge to an exact solution in some sense. The advantage of this concept is not only the fact that the problem is much easier for series of finite length, but it also generates a method for numerical approximation.
First results are obtained for and special step-potentials . A publication is work in progress. Another promising model is with .
