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 …

This review examines the tendency of light nuclei to exhibit clustering, where correlations
between nucleons result in the formation of precipitates, typically α particles. The …

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 …

The concept of a roton, a special kind of elementary excitation forming a minimum of energy
at finite momentum, has been essential for the understanding of the properties of superfluid …

Abstract The phenomenon of Bose-Einstein condensation of dilute gases in traps is
reviewed from a theoretical perspective. Mean-field theory provides a framework to …

The author presents a tutorial review of some ideas that are basic to our current
understanding of the phenomenon of Bose-Einstein condensation (BEC) in the dilute atomic …

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 …

Collapse in dipolar Bose-Einstein condensates may be arrested by quantum fluctuations.
Due to the anisotropy of the dipole-dipole interactions, the dipole-driven collapse induced by …

The realization of Bose-Einstein condensation (BEe) in dilute atomic gases [1-5] achieved
several long-standing goals. First, neutral atoms were cooled into the lowest energy state …

When atoms in a gas are cooled to extremely low temperatures, they will—under the
appropriate conditions—condense into a single quantum-mechanical state known as a Bose …
