Triangular vortex lattices and giant vortices in rotating bubble Bose-Einstein condensates
Angela C White
We show that three-dimensional spherical-shell condensates respond to rotation by forming two aligned triangular Abrikosov-like vortex lattices on each hemispherical surface. The c…
Perspective on Quantum Bubbles in Microgravity
Nathan Lundblad, David C. Aveline, Antun Balaz +13
Progress in understanding quantum systems has been driven by the exploration of the geometry, topology, and dimensionality of ultracold atomic systems. The NASA Cold Atom Laborator…
Oscillating superflow in multicomponent Bose-Einstein condensates
Angela White, Thomas Busch
Conservation of angular momentum depends on the existence of rotational symmetry. However, even in systems where this symmetry is broken, flipping between angular momentum eigensta…
Vinen turbulence via the decay of multicharged vortices in trapped atomic Bose-Einstein condensates
A. Cidrim, A. J. Allen, A. C. White +2
We investigate a procedure to generate turbulence in a trapped Bose-Einstein condensate which takes advantage of the decay of multicharged vortices. We show that the resulting sing…
Odd-petal states and persistent flows in spin-orbit-coupled Bose-Einstein condensates
Angela C White, Yongping Zhang, Thomas Busch
We study the phase diagram of a Rashba spin-orbit-coupled Bose-Einstein condensate confined in a two-dimensional toroidal trap. In the immiscible regime we find an azimuthally peri…
Moiré super-lattice structures in kicked Bose-Einstein condensates
L. J. O'Riordan, A. C. White, Th. Busch
Vortex lattices in rapidly rotating Bose-Einstein condensates lead to a periodic modulation of the superfluid density with a triangular symmetry. Here we show that this symmetry ca…
Emergence of Classical Rotation in Superfluid Bose-Einstein Condensates
Angela White, Tara Hennessy, Thomas Busch
Phase transitions can modify quantum behaviour on mesoscopic scales and give access to new and unusual quantum dynamics. Here we investigate the superfluid properties of a rotating…
Twisted unwinding of multi-charged quantum vortex and generation of turbulence in atomic Bose-Einstein condensates
G. D. Telles, P. E. S. Tavares, A. R. Fritsch +5
We report the observation of the twisted decay of quadruply charged vortices in an atomic Bose-Einstein condensate. Supporting numerical simulations show that the singly-charged vo…
Vortices and turbulence in trapped atomic condensates
Angela C. White, Brian P. Anderson, Vanderlei S. Bagnato
After over 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 roles of…
Topological stirring of two-dimensional atomic Bose-Einstein condensates
Angela White, Nick Proukakis, Carlo Barenghi
We stir vortices into a trapped quasi two-dimensional atomic Bose-Einstein condensate by moving three laser stirrers. We apply stirring protocols introduced by Boyland et. al. (200…
Non classical velocity statistics in a turbulent atomic Bose Einstein condensate
Angela White, Nick P. Proukakis, Carlo F. Barenghi
In a recent experiment Paoletti et al (Phys. Rev. Lett. 101, 154501, 2008) monitored the motion of tracer particles in turbulent superfluid helium and inferred that the velocity co…
