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”.
Our publication on the first-time observation of roton quasiparticles in quantum gases was chosen by the editors of Nature Physics as one of their favorite papers of the past 15 years.
A key step in creating controlled interactions in dipolar quantum mixtures is the characterization of interspecies Feshbach resonances.
Hagai has been awarded a postdoctoral fellowship for quantum science and technology from the Israel Council of Higher Education. As postdoc fellow, Hagai will study highly excited Erbium atoms trapped in a tweezer array in the T-REQS lab.
