Supersolids are fluid and solid at the same time. In jointly collaboration work, together with Thierry Giamarchi, theoretical physicist from the University of Geneva, we have for the first time investigated what happens when such a state is brought out of balance. We discovered a soft form of solid of high interest for science. As we report in Nature Physics, we were also able to reverse the process and restore supersolidity.
Bing Yang collaborate with Jad C. Halimeh, Robert Ott, Ian P. McCulloch and Philipp Hauke in theoretically studying the robustness of an ultracold-atom quantum simulator against defects. This work is now published on Physical Review Research and is highlighted as the “editor’s suggestion”.
In joint theoretical and experimental work with our theory colleagues A.-M. Rey (JILA) and B. Zhu (ITAMP) we investigate dipolar induced magnetization-conserving spin exchange dynamics with fermionic Er in a 3D optical lattice. Our work is now published in Physical Review Research.
The Physics magazine of the American Physical Society (APS) has named the discovery of supersolidity in ultracold quantum gases as one of the top ten highlights of 2019. The research group led by Francesca Ferlaino has for the first time obtained evidence of supersolidity in erbium and dysprosium gases. Similar experiments were conducted in Pisa and Stuttgart.
Together with an international Consortium of six other research groups Francesca Ferlaino in collaboration with Peter Zoller successfully applied for funding of the project “MAQS” – Magnetic-Atom Quantum Simulator.
