Quantized vortices in arbitrary dimensions and the normal-to-superfluid phase transition
The structure and energetics of superflow around quantized vortices, and the motion inherited by these vortices from this superflow, are explored in the general setting of a superfluid in arbitrary dimensions. The vortices may be idealized as objects of co-dimension two, such as one-dimensional …

Measurement of the density profile of quantized vortices and of the equation of state in a 3D interacting Bose gas
… accuracy. The first topic is about the shape of quantized vortices in an elongated condensate, with the goal of providing a quantitative analysis of the density structure of a quantized vortex filament hosted in a bulk 3D superfluid. We analyzed the shape of the vortex and studied its dynamics …

Visualization of the Vortex Lattice Dynamics in Superfluid Helium
… study the lattice structure and dynamics of the quantized vortices in superfluid helium-4 using a new rotating experiment. This setup includes control of the entire apparatus from the rotating frame, installation of a new EMCCD camera that allows for imaging of nanoscale tracer particles, and the …

Bosonic Quantum Hall States from Rapidly Rotating Bose-Einstein Condensates
… depleted regions of the condensate are full of quantized vortices, which enter the cloud causing it to turbulently evolve into a vortex liquid.

Novel ground states of Bose-condensed gases
… matter systems. Two of the recent frontiers, quantized vortices and ultracold molecules, are the subject of this thesis. The formation of highly-ordered vortex lattices in a Bose-condensed gas has been observed. These triangular lattices contain more than 150 vortices with lifetimes of several …

Imaging the shapes and dynamics of superfluid helium nanodroplets
… which is probably connected to the occurrence of quantized vortices in the spinning superfluid droplet.

Vortex Configurations Of Bosons In Rotating Optical Lattices
… cold atomic gases by driving the formation of quantized vortices. Here we explore the theory of vortices in an optical lattice. We first provide a detailed introduction section aimed at providing the reader with the information necessary to understand and appreciate the research presented in …

Exciton-polaritons in thermal equilibrium : from Bose-Einstein condensation to exciton-polaritonics
… such as condensation, superfluidity and quantized vortices at temperatures ranging from tens of Kelvin up to room temperatures. However, debates persist over whether the observed phenomena can be related to Bose- Einstein condensation because polaritons are not in thermal equilibrium. By …

Hollow condensates, topological ladders and quasiperiodic chains
… Bose-Einstein condensates and the behavior of vortices within them then discuss localization-delocalization physics of one-dimensional quasiperiodic models, and end by focusing on the physics of localized edge modes and topological phases in quasi-one-dimensional ladder models. For all three …
