Spin systems with discrete and continuous symmetry: topological defects, Bayesian statistics, quenched disorder and random fields

Project description

Spin systems with discrete and continuous symmetry under study

Spin systems are key models in statistical physics and condensed matter physics. Each vertex of a crystal lattice carries a spin that represents its magnetic orientation at this point. The spaces in which the spin takes its values fall under three classes: a discrete symmetry, a continuous and commutative symmetry and a continuous and non-commutative symmetry. The EU-funded Vortex project will investigate the geometry of the topological phase transitions and its associated vortices. In the case of the first two models, researchers will study the fractal geometry that appears when these two spin systems go through phase transitions. For the third model, they will examine the effect of a natural associated quenched disorder.
