Research interests

Analytical, mathematical, and computational research in the fields of

Resonant scattering of bright solitons in ultracold gases
Quantum many-body theories
Transport phenomena in Bose Einstein condensates
Dynamics of dark solitons in one-dimensional rings
Ultracold few-body systems
Entanglement and superpositions states in ultracold atoms

Software: QiwiB

QiwiB is a software package to simulate ultracold bosons in one dimension on a full quantum many-body level. Its source code including an HTML manual and installations instructions are included in the downloadable package below. Please read the provided README file located in the main directory.

The latest QiwiB package is available for download from our Google Code webpage (http://qiwib.googlecode.com/).
