Ultracold bosonic gases are ideal systems for studying nonlinear effects. I will discuss the stability and propagation dynamics of a certain class of
nonlinear excitations, known as "dark solitons". The talk will review theories of soliton decay due to trap confinement, dimensionality, and the
interaction with thermal cloud atoms. Numerical calculations will be presented in experimentally-relevant parameter regimes. Using soliton decay as a specific example, current theories of including finite temperature effects on condensate dynamics will be assessed.
(NB: Prof. Proukakis will be visiting the Dept. from May 10 -June 4).
