Project description:

Superfluidity is one of the most remarkable consequences of macroscopic quantum coherence in interacting condensed matter systems and manifests itself in a number of fascinating effects. This includes dissipationless flow of a superfluid and the formation of vortices with quantised circulation. First observed in liquid Helium in 1937, it is closely related to Bose-Einstein condensates and to the phenomena of superconductivity that arises in some materials.

In recent years, new techniques have been developed that have led to the direct experimental visualization of vortices in superfluids as reported in recent articles published in Nature/Science [Bewley et al. (2009), Gomez et al. (2014)]. New experiments are now being planned by different research groups that will use new types of particles to tag these vortices. These particles consist of exotic ion states that produce bubbles within the superfluid. Modelling the motion of these ions trapped within the bubbles and their interaction with the vortices will be essential in helping to interpret results to be obtained from these experiments. Exotic ions in these systems promise to reveal for the first time new direct evidence of novel vortex dynamics.

The primary tools to tackle the project will be a combination of theory and numerical simulations. Topics that are relevant to the described research include, fluid mechanics, quantum mechanics, nonlinear waves, numerical methods, and statistical mechanics. You will join an active and thriving research group working on the modelling of superfluid phenomena. The successful student will have the opportunity to interact with a number of other research groups. This project will place you at the frontier of a fast moving new subject, which promises many exciting career opportunities.

Interviews will take place between 16 January and 24 February 2017.

Person specification: The minimum entry requirement is 2:1 in Mathematics or Physics

Funding notes: This PhD project is in a Faculty of Science competition for funded studentships.  These studentships are funded for 3 years and comprise home/EU fees, an annual stipend of £14,296 and £1000 per annum to support research training.  Overseas applicants may apply but they are required to fund the difference between home/EU and overseas tuition fees (in 2016/17 the difference is £12,879 for the Schools of CHE & PHA, and £9,679 for CMP & MTH but fees are subject to an annual increase)
