Research interests

My main interests are in superfluid 3He and 4He, which include: quantized vortices and other topological defects, quantum turbulence.

I study quantum fluids, i.e. liquids at sufficiently low temperatures so that quantum properties of particles forming the liquid prevail (for example, the behaviour of fermions is markedly different from that of bosons at these temperatures). Liquid helium is a pure and simple liquid, yet at low temperatures it can show a great variety of new properties and orders. Some of these properties are similar to those of another available quantum fluid - electrons in metals.

There are two isotopes of helium: 4He (boson) and 3He (fermion). Owing to quantum effects they remain liquid to absolute zero. Both liquids show the phenomemon of superfluidity (fluid flow without viscosity) at sufficiently low temperatures (2 K and 2 mK respectively) but often in very different ways. They are excellent systems for testing our understanding of the quantum behaviour of condensed matter from first principles. Liquid 3He is the purest substance available for study and whilst being the simplest Fermi superfluid known it exhibits a wide array of interesting phenomena which result directly from the various symmetries which are spontaneously broken when its different superfluid states form.

Currently, our main interest is in the properties of turbulent superfluid 4He ("quantum turbulence") in the limit of zero temperature (i.e. when thermal excitations, "normal component", become irrelevant). The dynamics of tangles of vortex lines, especially their wavy behaviour and reconnections, is at the heart of this.

Very recently, we also investigated properties of mobile dislocations in solid helium at temperatures below 100mK.

I am the head of the Low Temperature Physics Group. To learn more about our research, check http://www.condmat.physics.manchester.ac.uk/researchthemes/quantumfluids/ and links from there.
