After decades of improvements in cooling techniques of several atomic species and in
finding methods for the achievement of stable quantum mixtures, the field is now ready for …

Dynamical quantum phase transitions are closely related to equilibrium quantum phase
transitions for ground states. Here, we report an experimental observation of a dynamical …

We experimentally investigate the dynamics of spin solitary waves (magnetic solitons) in a
harmonically trapped, binary superfluid mixture. We measure the in situ density of each …

In a trapped spin-1/2 Bose-Einstein condensate with miscible interactions, a two-
dimensional spin-orbit coupling can introduce an unconventional spatial separation …

The emergence of macroscopic coherence in a many-body quantum system is a ubiquitous
phenomenon across different physical systems and scales. This Chapter reviews key …

We present a magnetic sensor with energy resolution per bandwidth ER< ℏ. We show how a
87Rb single-domain spinor Bose–Einstein condensate, detected by nondestructive Faraday …

Excited-state quantum phase transitions depend on and reveal the structure of the whole
spectrum of many-body systems. While they are theoretically well understood, finding …

The minimization of the magnetic field plays a crucial role in ultracold gas research. For
instance, the contact interaction dominates all the other energy scales in the zero-magnetic …

In spinor Bose-Einstein condensates, spin-changing collisions are a remarkable proxy to
coherently realize macroscopic many-body quantum states. These processes have been …

We report the observation of stationary turbulence in antiferromagnetic spin-1 Bose-Einstein
condensates driven by a radio-frequency magnetic field. The magnetic driving injects energy …
