Quantum fluids are distinct from classical fluids in that both quantum mechanics and quantum statistics are required in order to explain their properties.

One of the most profound macroscopic manifestations of such quantum effects is the phenomena of superfluidity in which a fluid can flow without any dissipation and can rotate by creating quantized vortices. Members of the School of Mathematics who conduct research in this area are Davide Proment and Hayder Salman. We have close international links with a number of theoretical and experimental groups to model a range of phenomena arising in ultracold atomic Bose-Einstein condensates, vortex dynamics in liquid He-4, and nonequilibrium phenomena associated with systems driven far from equilibrium.
