Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

In recent years, the ability of cold atom experiments to explore condensed-matter-related
questions has dramatically progressed. Transport experiments, in particular, have expanded …

Simple models of interacting spins have an important role in physics. They capture the
properties of many magnetic materials, but also extend to other systems, such as bosons …

Exact solutions for quantum many-body systems are rare but provide valuable insights for
the description of universal phenomena such as the non-equilibrium dynamics of strongly …

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 …

In Heisenberg models with exchange anisotropy, transverse spin components are not
conserved and can decay not only by transport, but also by dephasing. Here, we utilize …

Here we review the field of atom chips in the context of Bose–Einstein Condensates (BEC)
as well as cold matter in general. Twenty years after the first realization of the BEC and 15 …

A proposed paradigm for out-of-equilibrium quantum systems is that an analog of quantum
phase transitions exists between parameter regimes of qualitatively distinct time-dependent …

Ferromagnetism is a manifestation of strong repulsive interactions between itinerant
fermions in condensed matter. Whether short-ranged repulsion alone is sufficient to stabilize …

Ultracold atoms confined by engineered magnetic or optical potentials are ideal to study
phenomena otherwise difficult to realize or probe in the solid state, thanks to the ability to …
