The physics of one-dimensional interacting bosonic systems is reviewed. Beginning with
results from exactly solvable models and computational approaches, the concept of bosonic …

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 …

We study the spectrum of elementary excitations of a dipolar Bose gas in a three-
dimensional anisotropic trap across the superfluid-supersolid phase transition. Theoretically …

A supersolid is a counter-intuitive state of matter that combines the frictionless flow of a
superfluid with the crystal-like periodic density modulation of a solid,. Since the first …

Insights into complex phenomena in quantum matter can be gained from simulation
experiments with ultracold atoms, especially in cases where theoretical characterization is …

Ultracold atoms confined to periodic potentials have proven to be a powerful tool for
quantum simulation of complex many-body systems. We confine fermions to one dimension …

We measure the excitation spectrum of a stable dipolar Bose-Einstein condensate over a
wide momentum range via Bragg spectroscopy. We precisely control the relative strength ε …

Second sound attenuation, a distinctive dissipative hydrodynamic phenomenon in a
superfluid, is crucial for understanding superfluidity and elucidating critical phenomena …

Ultracold atomic gases are a powerful tool to experimentally study strongly correlated
quantum many-body systems. In particular, ultracold Fermi gases with tunable interactions …

We show that short-range pair correlations in a strongly interacting Fermi gas follow a simple
universal law described by Tan's relations. This is achieved through measurements of the …
