About Me

I am an Affiliated Lecturer in the Quantum Matter group with an interest in correlated electron systems such as superconductors, novel magnets and heavy fermion materials. My research makes extensive use of the Cavendish 'Big Fridge' facility, a custom-designed laboratory for exploring matter at the extremes of temperature, pressure and magnetic field. I am also a Fellow of Corpus Christi College, Cambridge, where I direct studies in physics.

Research Interests

Low Temperature Heat and Charge Transport

Measuring the ability of a material to transport heat at very low temperatures has emerged as a useful probe of correlated electron systems, as heat transport offers direct access to the low-energy electronic excitations which are characteristic of the quantum ground state.
QCP
One interesting case involves materials which a close to a quantum critical point (QCP). This situation is depicted in the phase diagram for a material with a phase transition at zero temperature at left. The unstable point between these two phases, the QCP, is indicated here by the dark blue point. Our recent work has shown that even in this exotic situation, the standard framework for describing interacting electrons in a material, is still valid. At the QCP the same particles that carry heat also carry charge, in a way that would be expected in normal metal (Sutherland et al, PRB(R) 2015).

Such measurements can also be useful in superconductors, as they can allow us to distinguish between a superconducting gap that remains finite everywhere in reciprocal space, and one that vanishes along some special directions (ie. has nodes). See for instance, the study of LaFePO (Sutherland et al, PRB 2012).

Electronic Structure

YbALB4
The electronic structure of a metallic material is the fundamental starting place for understanding how interesting material properties such as magnetism or superconductivity arise. The Fermi surface is a useful concept in this regard - it is the contour of constant energy which divides filled and unfilled electron states in reciprocal space. The de-Haas van-Alphen (dHvA) effect, which occurs in a strong magnetic field, can directly measure the shape of the Fermi surface as well as give information about electron correlations. One striking example involves the use of the dHvA technique to study the heavy Fermion material YbAlB4, with the calculated Fermi surface shown at right. This compound appears to be near a magnetic instability at zero applied pressure and field, leading to unusual transport, magnetic and thermodynamic properties (O'Farrell et al, PRB 2009). Other ongoing work involves studying the quasi-skutterudite system (Ca/Sr)3Ir4Sn13, which appears to play host to quantum critical phenomena driven by proximity to a structural phase transition.

Advanced Measurement Techniques

Piezoresistive cantilever
The Quantum Matter 'Big Fridge' facility has been upgraded in 2016. It now has a superconducting magnet capable of providing magnetic fields of up to 20.4 T, which is combined with a dilution refrigerator with a base temperature in the single millikelvin regime. Postdoctoral research fellow Jordan Baglo is pictured at right removing some of the low temperature insulation ahead of the magnet upgrade. Taken together, this facilty offers an exceptionally high ratio of B/T, which improves the chance of observing quantum oscillations in systems with heavy masses, such as heavy fermion materials or those near a quantum critical point. A series of bespoke electronics including low temperature transformers is used to maximize signal to noise ratios. We are actively developing new techniques for the system, including the capability of studying quantum oscillations under hydrostatic pressure using magnetic susceptibility, and tunnel diode oscillator techniques.

PhD projects

If you are a prospective graduate student who is interested in this type of research and would like to know more, please don't hesitate to contact me. I'm always available to discuss potential projects and research ideas. Most of the projects on offer would involve some technique development, measurements at high magnetic fields and low temperature in Cambridge and at facilities abroad, as well as materials preparation and characterisation.
