Project Description

The experimental realization of Bose-Einstein Condensates (BEC) was awarded the Physics Nobel prize in 2001. In many practical applications, the cloud of BEC atoms is loaded in a spatially periodic trap generated by two counter-propagating lasers (optical lattice). The (simple) equations describing the interactions of BEC in potential wells of the optical lattice are identical to those describing laser light propagating in arrays of waveguides. Very unusual and complex behaviour may occur, from self-localisation to generation of vortices and turbulence. More recently, we have found that the thermodynamics of these systems involves states at negative temperatures and novel properties of heat transport.The project focuses on the theoretical and numerical analysis of these complex and intriguing features. Simulations are done in collaboration with research groups performing experiments on BEC and/or optical waveguides at Strathclyde, Imperial College, Florence (Italy), Pisa (Italy), Paris (France) and Münster (Germany).

PhD students will join Strathclyde's CNQO group, which was "flagged" for its high-quality research.
