Most recent: monopole currents in spin ice - read here

My interests lie in problems in condensed matter and statistical mechanics. Specialties include model magnetism, frustrated systems, phase transitions in confined geometry and finite size effects in correlated systems. Recently I have been working on models of “spin ice”, realized experimentally Holmium and Dysprosium Titanate. These materials are characterized by low energy magnetic excitations that “fractionalize” into quasi-particles carrying magnetic charge - magnetic monopoles. This Coulomb gas, in the grand canonical ensemble, shares many properties of a weak electrolyte - a “magnetolyte”.
