A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

The first book dedicated to this new and powerful computational method begins with a
comprehensive description of MCTDH and its theoretical background. There then follows a …

Knowing when a physical system has reached sufficient size for its macroscopic properties
to be well described by many-body theory is difficult. We investigated the crossover from few …

The interplay of strong interactions and magnetic fields gives rise to unusual forms of
superconductivity and magnetism in quantum many-body systems. Here, we present an …

Abstract The attractive Fermi–Hubbard model is the simplest theoretical model for studying
pairing and superconductivity of fermions on a lattice. It exhibits many interesting features …

Recent theoretical and experimental progress on studying one-dimensional systems of
bosonic, fermionic, and Bose–Fermi mixtures of a few ultracold atoms confined in traps is …

We study quasi-one-dimensional few-particle systems consisting of one to six ultracold
fermionic atoms in two different spin states with attractive interactions. We probe the system …

Thermodynamic properties of matter are conveniently expressed as functional relations
between variables known as equations of state. Here we experimentally determine the …

We report on the experimental realization of a state-dependent lattice for a two-orbital
fermionic quantum gas with strong interorbital spin exchange. In our state-dependent lattice …
