Topological Solitons/Numerical Analysis Seminar: Dynamics of Solitons and Vortex Rings in Bose-Einstein Condensates

Presented by Joachim Brand,

7 February 2006 13:05 in CM221

"Bose-Einstein condensates provide a newly accessible medium for the experimental study of nonlinear wave phenomena. Experimental constraints introduce new aspects in addition to the well-known soliton phenomena of the nonlinear Schroedinger equation. How much of the classical particle-like properties of solitons remain in this situation? In this talk I will discuss how bright matter-wave solitons can aquire dissipative and non-classical properties. I will also discuss the influence of transverse degrees of freedom on the collisional dynamics of dark solitons and vortex rings in cylindrical Bose-Einstein condensates. We find peculiar transient structures of spherical shape in inelastic collisions. Finally, I will discuss a recent experimental study of nonlinear-wave collisions."
