Gauge fields are central in our modern understanding of physics at all scales. At the highest
energy scales known, the microscopic universe is governed by particles interacting with …

This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

Strong electron correlations lie at the origin of high-temperature superconductivity. Its
essence is believed to be captured by the Fermi-Hubbard model of repulsively interacting …

Nano-and micromechanical solid-state quantum devices have become a focus of attention.
Reliably generating nonclassical states of their motion is of interest both for addressing …

The formation of strongly correlated fermion pairs is fundamental for the emergence of
fermionic superfluidity and superconductivity. For instance, Cooper pairs made of two …

Full control over the dynamics of interacting, indistinguishable quantum particles is an
important prerequisite for the experimental study of strongly correlated quantum matter and …

The physics of quantum degenerate atomic Fermi gases in uniform as well as in
harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is …

Interference with atomic and molecular matter waves is a rich branch of atomic physics and
quantum optics. It started with atom diffraction from crystal surfaces and the separated …

The Pauli exclusion principle is one of the most fundamental manifestations of quantum
statistics. Here, we report on its local observation in a spin-polarized degenerate gas of …

The Fermi-Hubbard model is a key concept in condensed matter physics and provides
crucial insights into electronic and magnetic properties of materials. Yet, the intricate nature …
