Many-body systems that are set rotating may form vortices, characterized by rotating motion around a central cavity. This is familiar to us from every-day life: you can observe vortices while stirring your coffee, or watching a hurricane. In quantum physics, vortices are known to occur in superconducting films and rotating bosonic He-4 or fermionic He-3 liquids, and recently became a hot topic in the research on cold atoms in traps.
The speaker will address this fascinating subject and will describe the close relationship between rotating Bose-Einstein condensates and quantum dots in the presence of strong magnetic fields.
