Time: 2:00 - 4:00pm
Speaker: Dr Joe Paddison
Venue: G. O. Jones Building, Room 610

Geometrical frustration – the inability of a material to satisfy all of its interactions simultaneously – can generate intriguing states of matter that are disordered yet strongly correlated. Probably the most famous examples are cubic water ice and its magnetic analogue, spin ice. In this talk, I’ll introduce how “ice rules” help us to understand disorder in magnetic and non-magnetic materials. I’ll discuss the signatures of ice-like disorder in scattering measurements, and how the concept can be extended to two-dimensional and quantum-entangled systems.
