Prof Steve Bramwell

Biography

• Neutron scattering
• Magnetism
• Statistical Mechanics 

Research interests:

I design and investigate "model magnets": simple materials that are intended to capture the physics of complex interacting systems.  Ideas that have emerged from my work include those of "spin ice", the "BHP" probability distribution and the universal exponent b = 3p2/128 (see refs. 1-3). These ideas have impacted many fields, including condensed matter, turbulence and nanotechnology (see, for example, refs. 4-6).
