A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

The emergence of quasiparticles in interacting matter represents one of the cornerstones of
modern physics. However, in the vicinity of a quantum critical point, the existence of …

We have observed the Bose-Einstein condensation of an atomic gas in the (quasi) uniform
three-dimensional potential of an optical box trap. Condensation is seen in the bimodal …

We review the recent theoretical and experimental progress regarding the generalized
hydrodynamics (GHD) behavior of the one-dimensional (1D) Bose gas with contact …

Abstract The Feynman-Tan relation, obtained by combining the Feynman energy relation
with the Tan's two-body contact, can explain the excitation spectra of strongly interacting 39K …

From neutron stars to high-temperature superconductors, strongly interacting many-body
systems at or near quantum degeneracy are a rich source of intriguing phenomena. The …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

We observe two consecutive heteronuclear Efimov resonances in an ultracold Li-Cs mixture
by measuring three-body loss coefficients as a function of magnetic field near a Feshbach …

The foundation of atomic physics is the arsenal of spectroscopic tools to probe individual
atoms and molecules with astounding precision. With the advent of ultracold quantum …
