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 …

Scale invariance and self-similarity in physics provide a unified framework for classifying
phases of matter and dynamical properties near equilibrium in both classical and quantum …

We report on the observation of half-quantum vortices (HQVs) in the easy-plane polar phase
of an antiferromagnetic spinor Bose-Einstein condensate. Using in situ magnetization …

We report on the experimental observation of vortex cluster shedding from a moving
obstacle in an oblate atomic Bose-Einstein condensate. At low obstacle velocities v above a …

Topological defects and smooth excitations determine the properties of systems showing
collective order. We introduce a generic non-singular field theory that comprehensively …

We probe local phase fluctuations of trapped two-dimensional Bose gases using matter-
wave interferometry. This enables us to measure the phase correlation function, which …

Quantum vortices in atomic Bose–Einstein condensates (BECs) are topological defects
characterized by quantized circulation of particles around them. In experimental studies …

We study computationally dynamics of quantized vortices in two-dimensional superfluid
Bose-Einstein condensates confined in highly oblate power-law traps. We have found that …

We investigate vortex shedding from a moving penetrable obstacle in a highly oblate Bose-
Einstein condensate. The penetrable obstacle is formed by a repulsive Gaussian laser beam …

Stable self-trapped vortex annuli (VA) with large values of topological charge S (giant VA)
not only are a subject of fundamental interest, but are also sought for various applications …
