Research

I am a research fellow in the Theory of Condensed Matter Group, University of Cambridge. My research is focused on strongly correlated phenomena and concurrent materials design.

Strongly correlated phenomena

An electron gas with contact repulsive interactions is a deceptively simple interacting system, yet it displays a remarkably rich range of phenomena. At mean-field level the electron gas was predicted by Stoner to undergo a mean-field transition into an itinerant ferromagnet. This phase has never been cleanly observed in the solid state, however we studied the first experimental exploration of its properties in an ultracold atomic gas. Moreover, quantum fluctuations mean that a variety of other inhomogeneous magnetic states are energetically favorable, with our suggestion of a spin spiral state being first observed in CeFePO in 2012.

A few-fermion ultracold atom system presents an alternative arena to study strongly interacting fermions. The system allows strong correlations to be probed and explained within an exactly solvable and experimentally measurable system, which when mastered will allow the intuition and understanding to be built up for a many-body system. Our study of the consequences of repulsive and attractive interactions in this system was followed by the experimental realization and characterization of a few-atom Fermi sea.

Concurrent materials design

We have proposed, implemented, and employed a novel computer code to discover four new alloy families. The alloys include a nickel-based alloy for turbine discs in jet engines, an alloy for lining the combustion chamber of a jet engine, and two molybdenum forging alloys. Each alloy has thirteen individual physical properties that are predicted to match or exceed commercially available alternatives, and for each alloy eight properties have been experimentally verified. The alloys are now undergoing compliance testing by Rolls Royce plc.

Through the stone, bronze, and iron ages the discovery of new materials has chronicled human history. The coming of each age was sparked by the chance discovery of a new metal. Despite the central importance of materials in enabling breakthrough technologies, even today the only way to develop new materials is through experimental driven trial and improvement. In our research we are developing the techniques to now understand and design new materials by calculating its properties on a computer.
