This paper proposes a simple setup for introducing an artificial magnetic field for neutral
atoms in 2D optical lattices. This setup is based on the phenomenon of photon-assisted …

The interaction of matter–wave solitons with a potential barrier is a fundamentally important
problem, and the splitting and subsequent recombination of the soliton by the barrier is the …

We study atomic Bloch oscillations in an ensemble of one-dimensional tilted superfluids in
the Bose-Hubbard regime. For large values of the tilt, we observe interaction-induced …

We observe the coherence of an interacting two-component Bose-Einstein condensate
(BEC) surviving for seconds in a trapped Ramsey interferometer. Mean-field-driven …

We experimentally study the dynamics of weakly interacting Bose-Einstein condensates of
cesium atoms in a 1D optical lattice with a periodic driving force. After a sudden start of the …

The Kuramoto model constitutes a paradigmatic model for the dissipative collective
dynamics of coupled oscillators, characterizing in particular the emergence of synchrony …

We demonstrate two-dimensional arrays of Bose-Einstein condensates (BECs) as a new
experimental platform with parallel quantum simulation capability. A defect-free array of up …

Matter–wave interferometry is a powerful tool for high-precision measurements of the
quantum properties of atoms, many-body phenomena and gravity. The most precise matter …

We report an experimental realization of ultracold atoms confined in a time-averaged,
adiabatic potential (TAAP). This trap** technique involves using a slowly oscillating …

Quantum carpets—the spatio-temporal de Broglie density profiles—woven by an atom or an
electron in the near-field region of a diffraction grating bring to light, in real time, the …
