Challenges of Low-Dimensional Quantum Gases: Brazilian-German Wilhelm and Else Heraeus Seminar

This binational Wilhelm and Else Heraeus Seminar organized by ICTP-SAIFR will bring together primarily scientists from Brazil and Germany to discuss both the challenges and the prospects for quantum gases in spatial dimensions lower than three. Scientists from other parts of the world will also participate and provide a global perspective of recent developments. In addition to plenary sessions, where leading experts on quantum gases will present their latest work, the seminar will have contributed talks by some young participants and poster sessions to disseminate widely the research of all attendees. In recent years it has turned out that low-dimensional quantum gas systems are quite challenging due to the enhanced impact of quantum and thermal fluctuations upon static and dynamic properties. Therefore, the planned Brazilian-German Wilhelm and Else Heraeus Seminar focuses upon such low-dimensional quantum gases and discusses their respective challenges and prospects. In particular we have in mind to highlight. - two-dimensional quantum gas systems with properties, which do not exist in their three-dimensional - counterparts as, for instance, the fractional quantum Hall effect or the Berezinskii-Kosterlitz-Thouless phase transition, - quantum gases in a microgravity bubble trap in order to investigate how the differential geometry of a closed surface affects the system properties, - photon Bose-Einstein condensates in dye-filled microcavities and semiconductor lasers with their potential technological applications, - anyonic statistics realized by bosonic or fermionic atoms in one-dimensional lattices in order to obtain a deeper understanding of the intriguing statistical interaction, which is omnipresent in the quantum realm due to the indistinguishability of identical quantum particles. There is no registration fee. The Wilhelm and Else Heraeus-Foundation bears the cost of meals for accepted participants from Sao Paulo and the cost of full-board accommodation for accepted participants that are not from Sao Paulo.
