Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

Over the last decade impressive progress has been made in the theoretical understanding
of transport properties of clean, one-dimensional quantum lattice systems. Many physically …

Intriguingly, quantum many-body systems may defy thermalization even without disorder.
One example is so-called fragmented models, where the many-body Hilbert space …

Many-body localization (MBL), the disorder-induced localization of interacting particles,
signals a breakdown of conventional thermodynamics because MBL systems do not …

A particular strength of ultracold quantum gases is the range of versatile detection methods
that are available. As they are based on atom–light interactions, the whole quantum optics …

Strontium optical lattice clocks have the potential to simultaneously interrogate millions of
atoms with a high spectroscopic quality factor of 4× 1017. Previously, atomic interactions …

The repulsive Hubbard Hamiltonian is one of the foundational models describing strongly
correlated electrons and is believed to capture essential aspects of high-temperature …

Ultracold quantum gases offer a unique setting for quantum simulation of interacting many-
body systems. The high degree of controllability, the novel detection possibilities and the …

We realize a quantum-gas microscope for fermionic K 40 atoms trapped in an optical lattice,
which allows one to probe strongly correlated fermions at the single-atom level. We combine …

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 …
