Quantized vortices are a prototypical feature of superfluidity that have been observed in
multiple quantum gas experiments. But the occurrence of vortices in dipolar quantum gases …

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

We present the first experimental evidence, supported by theory and simulation, of
spatiotemporal optical vortices (STOVs). A STOV is an optical vortex with phase and energy …

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 quantum Kibble-Zurek mechanism (QKZM) predicts universal dynamical behavior near
the quantum phase transitions (QPTs). It is now well understood for the one-dimensional …

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 …

Reconnections and interactions of filamentary coherent structures play a fundamental role in
the dynamics of fluids, redistributing energy and helicity among the length scales and …

We experimentally investigate the dynamics of spin solitary waves (magnetic solitons) in a
harmonically trapped, binary superfluid mixture. We measure the in situ density of each …

The field of ultracold atomic physics has developed rapidly during the last two decades, and
currently encompasses a broad range of topics in physics, with a variety of important …

Quantum vortices are often endowed with an effective inertial mass, due, for example, to
massive particles in their cores. Such “massive vortices” display new phenomena beyond …
