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

Turbulence, the complicated fluid behavior of nonlinear and statistical nature, arises in many
physical systems across various disciplines, from tiny laboratory scales to geophysical and …

Persistent currents in annular geometries have played an important role in disclosing the
quantum phase coherence of superconductors and mesoscopic electronic systems …

In this article, we reinvestigate the Kraenkel-Manna-Merle (KMM) system, which can
describe the nonlinear ultra-short wave pulse motions in certain saturated ferromagnetic …

When a system crosses a second-order phase transition on a finite timescale, spontaneous
symmetry breaking can cause the development of domains with independent order …

The aim of this introductory article is two-fold. First, we aim to offer a general introduction to
the theme of Bose-Einstein condensates, and briefly discuss the evolution of a number of …

The Josephson effect is a macroscopic quantum phenomenon that reveals the broken
symmetry associated with any superfluid state. Here we report on the observation of the …

We observe solitonic vortices in an atomic Bose-Einstein condensate (BEC) after free
expansion. Clear signatures of the nature of such defects are the twisted planar density …

Collective particle transport across periodic energy landscapes is ubiquitously present in
many condensed matter systems spanning from vortices in high-temperature …

We observe a long-lived solitary wave in a superfluid Fermi gas of Li 6 atoms after phase
imprinting. Tomographic imaging reveals the excitation to be a solitonic vortex, oriented …
