We observe monopole oscillations in a mixture of Bose-Einstein condensates, where the
usually dominant mean-field interactions are canceled. In this case, the system is governed …

Synthetic dimensions provide a powerful approach for simulating condensed matter physics
in cold atoms and photonics, whereby a set of discrete degrees of freedom are coupled …

Quantum mechanics predicts that our physical reality is influenced by events that can
potentially happen but factually do not occur. Interaction-free measurements (IFMs) exploit …

Compared to single-component Bose-Einstein condensates, spinor Bose-Einstein
condensates display much richer dynamics. In addition to density oscillations, spinor Bose …

Whether quantum correlations between identical particles can serve as a resource for
quantum information protocols has often been questioned, since the constituent particles are …

We have investigated spin dynamics in a two-dimensional quantum gas. Through spin-
changing collisions, two clouds with opposite spin orientations are spontaneously created in …

If the boundary conditions of the quantum vacuum are changed in time, quantum field theory
predicts that real, observable particles can be created in the initially empty modes. Here, we …

We present interferometeric measurements of the f= 1 to f= 2 interhyperfine scattering
lengths in a single-domain spinor Bose-Einstein condensate of Rb 87. The interhyperfine …

We study the thermodynamic properties of a spin-1 Bose gas across the Bose–Einstein
condensation transition. We present the theoretical description of the thermodynamics of a …

We study spontaneous symmetry breaking (SSB), Josephson oscillation, and self-trap** in
a stable, mobile, three-dimensional matter-wave spherical quantum ball self-bound by …
