This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

This book deals with applications in several areas of science and technology that make use
of light which carries orbital angular momentum. In most practical scenarios, the angular …

We demonstrate the coherent transfer of the orbital angular momentum of a photon to an
atom in quantized units of ℏ, using a 2-photon stimulated Raman process with Laguerre …

We investigate the collapse dynamics of a dipolar condensate of Cr 52 atoms when the s-
wave scattering length characterizing the contact interaction is reduced below a critical …

Abstract Experiments with Bose–Einstein condensates of dilute atomic gases require
temperatures as low as hundreds of nanokelvins but obviously cannot be performed at zero …

We study the metastability and decay of multiply charged superflow in a ring-shaped atomic
Bose-Einstein condensate. Supercurrent corresponding to a giant vortex with topological …

We present experimental results on a Bose gas in a quasi-2D geometry near the Berezinskii,
Kosterlitz, and Thouless (BKT) transition temperature. By measuring the density profile after …

We present the creation and time evolution of two-dimensional Skyrmion excitations in an
antiferromagnetic spinor Bose-Einstein condensate. Using a spin rotation method, 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 …

After more than a decade of experiments generating and studying the physics of quantized
vortices in atomic gas Bose–Einstein condensates, research is beginning to focus on the …
