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 …

Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

Ultralight bosons can affect the dynamics of spinning black holes (BHs) via superradiant
instability, which can lead to a time evolution of the supermassive BH shadow. We study …

In a joint experimental and theoretical effort, we report on the formation of a macrodroplet
state in an ultracold bosonic gas of erbium atoms with strong dipolar interactions. By precise …

Substantial leaps in the understanding of quantum systems have been driven by exploring
geometry, topology, dimensionality and interactions in ultracold atomic ensembles,,,,–. A …

This paper reviews the recent theoretical and experimental advances in the study of ultra-
cold gases made of bosonic particles interacting via the long-range, anisotropic dipole …

This paper presents a review of the current state of the art in the research field of cold and
ultracold molecules. It serves as an introduction to the focus issue ofNew Journal of Physics …

We report the production of matter-wave solitons in an ultracold lithium-7 gas. The effective
interaction between atoms in a Bose-Einstein condensate is tuned with a Feshbach …

Bose-Einstein condensation, or BEC, has a long and rich history dating from the early
1920s. In this article we will trace briefly over this history and some of the developments in …

Magnetically tunable Feshbach resonances were employed to associate cold diatomic
molecules in a series of experiments involving both atomic Bose and two-spin-component …
