Anyon Physics of Ultracold Atomic Gases

Technische Universität Kaiserslautern (Germany), December 10 - 14, 2018

The topological properties in one and two space dimensions allow for quantum particles to have a statistics, which can vary continuously from boson to fermion ones and is therefore called anyons. Such anyonic particles are becoming of increasing importance in condensed matter physics and quantum computation. They may play an essential role for describing the fractional quantum Hall effect, high-temperature superconductivity, and the physics of topological insulators and superconductors. Several proposals in the literature indicate the possibility to use the high degree of tunability of ultracold quantum gases as a quantum simulator in the sense of Richard Feynman in order to realize anyon physics. The International School and Workshop at the Technische Universität Kaiserslautern (Germany) provides pedagogical introductory lectures as well as research talks upon both anyon physics in general and their possible realization in the realm of ultracold quantum gases. Due to the mutual support of the VolkswagenStiftung as well as the Sonderforschungsbereich/Transregio 49, the Sonderforschungsbereich/Transregio 185, and the Research Center OPTIMAS this International School and Workshop is the third one of three conferences on this intriguing topic. The first one was an International School at the Freie Universität Berlin (Germany) in the period September 24 - 28, 2013, whereas the second one was an International School and Workshop, which took place at the Technische Universität Kaiserslautern (Germany) in the period December 12 - 15, 2014. Finally, please note that the third International School and Workshop at the Technische Universität Kaiserslautern (Germany) represents a satellite event to the 685th Wilhelm and Else Heraeus Seminar "Research Frontiers in Ultracold Quantum Gases" which takes place at the Physics Center in Bad Honnef (Germany) in the subsequent period December 17 - 21, 2018.
