 Topological Solitons
Topological solitons are stable, finite energy, particlelike solutions of nonlinear wave equations. They arise in a variety of applications in several areas including particle physics, cosmology and condensed matter physics. Here are some examples of 3D topological solitons in which I am interested.

 Skyrmions/Planar Skyrmions
Skyrmions are interesting both from a mathematical point of view and as a powerful candidate for a solitonic description of nuclei, where the number of solitons is equivalent to the baryon number. The Skyrme model is a 3d field theory and has a 2d analogue in the form of planar skyrmions. There are also many different topological solitons (e.g. monopoles and instantons) which can be related to the Skyrme model.
Moreover, many different techniques can be applied to this model. One way is to solve the equations numerically with the help of a large computer. However, often more insight is gained by using approximations.

 Vorticies
Vorticies are topological solitons in a two dimensional gauge theory that appear in superconducting systems through the GinzbergLandau equations. When extended to the full 3d model they represent vortex strings of magnetic flux through a superconducting sample. In particular I have an interest in multicomponenet systems that lead to interesting vortex interactions and has generate a large amount of interest in both theoretical and experimental physics. There are also interesting results in considering vorticies on other Riemannian surfaces, this can make the moduli space more tractable than the flat plane case.
