Thermography of the superfluid transition in a strongly interacting Fermi gas
Heat transport can serve as a fingerprint identifying different states of matter. In a normal
liquid, a hotspot diffuses, whereas in a superfluid, heat propagates as a wave called “second …

Cold-Atom Elevator: From Edge-State Injection to the Preparation of Fractional Chern Insulators
Optical box traps offer new possibilities for quantum-gas experiments. Building on their
exquisite spatial and temporal control, we propose to engineer system-reservoir …

Emergence of isotropy and dynamic scaling in 2D wave turbulence in a homogeneous Bose gas
We realize a turbulent cascade of wave excitations in a homogeneous 2D Bose gas and
probe on all relevant time and length scales how it builds up from small to large momenta …

Universal equation of state for wave turbulence in a quantum gas
Boyle's 1662 observation that the volume of a gas is, at constant temperature, inversely
proportional to pressure, offered a prototypical example of how an equation of state (EoS) …

First and second sound in a compressible 3D Bose fluid
The two-fluid model is fundamental for the description of superfluidity. In the nearly
incompressible liquid regime, it successfully describes first and second sound …
