Nonlinear Schrodinger equations:
how can mathematicians be really useful for physicists ?!
Modeling and Simulation of Bose-Einstein condensates (BECs) |
We scetch key issues of modeling and numerics of NLS like Gross-Pitaevskii
equations.
We present 3-d simulations of the dynamics of BECs (done in interaction with the Atomchip group at TU Wien) and work out the interplay "physics " - > "mathematical modeling / numerical technique" required for each phase of the experiment, like "switch off trap" -> "switch from homogeneous Dirichlet boundary conditions to absorbing boundary conditions", or "expansion phase" -> "rescaling of the domain", or "free flight" -> "switch to linear Schrödinger equation"...
