The Feynman-Tan relation, obtained by combining Feynman energy relation with Tan's two-body contact, explained excitation spectra of strongly interacting quantum gases of 39K atoms. However, whether Feynman-Tan relation is ...
Physicists are increasingly using ultracold molecules to study quantum states of matter. Many researchers contend that molecules have advantages over other alternatives, such as trapped ions, atoms or photons. These advantages ...
Quantized vortices can be generated in classical experiments of liquid helium and ultracold dilute gases to conduct fundamental and comparative studies of different superfluids. In a new report published in Science Advances, ...
Physicists at the University of Bonn have experimentally proven that an important theorem of statistical physics applies to so-called "Bose-Einstein condensates." Their results now make it possible to measure certain properties ...
Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition ...
Recently, the team led by Prof. Zeng Changgan from the University of Sciences and Technology of China (USTC) of the Chinese Academy of Sciences, collaborating with Li Xiaoguang's team from Shenzhen University, has enabled ...
Recently, a research team led by Prof. Pan Jianwei and Prof. Zhao Bo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), used adiabatic magneto-association to create an ...
Scientists have shown how three vortices can be linked in a way that prevents them from being dismantled. The structure of the links resembles a pattern used by Vikings and other ancient cultures, although this study focused ...
A team of researchers at Universität Heidelberg has built an early universe analog in their laboratory using chilled potassium atoms. In their paper published in the journal Nature, the group describes their simulator and ...
Two superfluids can exist at the same time in ultracold atomic clouds. Until now, their coexistence could not be observed experimentally. Now, however, physicists from Heidelberg University have demonstrated such a magnetic ...
