This report addresses topics and questions of common interest in the fields of ultra-cold
gases and nuclear physics in the context of the BCS–BEC crossover. By this crossover, the …

This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

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 …

Correlations in systems with spin degree of freedom are at the heart of fundamental
phenomena, ranging from magnetism to superconductivity. The effects of correlations …

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 …

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 …

Spontaneous symmetry breaking is a central paradigm of elementary particle physics,
magnetism, superfluidity and superconductivity. According to Goldstone's theorem, phase …

We investigate the properties of self-bound ultradilute Bose-Bose mixtures, beyond the Lee-
Huang-Yang description. Our approach is based on the determination of the beyond mean …

We review recent experimental and theoretical progress in realizing and simulating many-
body phases of ultracold atoms in optical lattices, which gives access to analog quantum …

By calculating the density response function we identify the excitation spectrum of a Bose-
Einstein condensate with equal Rashba and Dresselhaus spin-orbit coupling. We find that …
