A density-functional approach to fermionization in the 1D Bose gas
Joachim Brand
A time-dependent Kohn-Sham scheme for 1D bosons with contact interaction is derived based on a model of spinor fermions. This model is specifically designed for the study of the st…

A Levinson theorem for scattering from a Bose-Einstein condensate
J. Brand, I. Haering, J. -M. Rost
A relation between the number of bound collective excitations of an atomic Bose-Einstein condensate and the phase shift of elastically scattered atoms is derived. Within the Bogoli…

Svortices and the fundamental modes of the "snake instability": Possibility of observation in the gaseous Bose-Einstein Condensate
Joachim Brand, William P. Reinhardt
The connection between quantized vortices and dark solitons in a long and thin, waveguide-like trap geometry is explored in the framework of the non-linear Schrödinger equation. Va…
