Polar-core spin vortices in a spin-1 condensate: relevance and point-vortex modelling
Speaker: Lewis Williamson
Affiliation: University of Queensland
Abstract
Atoms in a spin-1 condensate have access to three magnetic sublevels. In addition to mass currents, a spin-1 condensate supports spin currents, which can have circulating flows that give rise to different vortex types. In this talk I will discuss a particular type of spin vortex known as a polar-core spin vortex (PCV). I will discuss the role of PCVs in a range of equilibrium and nonequilibrium processes, ranging from quantum phase transitions to turbulence, highlighting areas that deserve more exploration. I will then discuss recent results on a point-vortex model of PCV dynamics, which sheds light on fundamental differences between PCVs and scalar condensate vortices at both the microscopic and macroscopic level.
About Physics Seminars
The weekly Physics Seminar series focuses on a broad range of physics research within SMP, along with frequent presentations from visiting researchers. Seminars are usually scheduled for 1.00pm on Tuesdays.
The talks are typically more specialised than a colloquium but are often attended by staff and PhD students across a broad range of areas. Speakers are thus encouraged to include introductory material in the talks.
All SMP researchers and HDR students are encouraged to speak. Please email Lewis Williamson to register your interest.
The seminars are open so there is no need to register your attendance.
