Gordon Godfrey Theoretical Seminar 2005 Spinons and gauge degrees of freedom in spin liquids Dr.
Gregoire Misguich Date
Tuesday, 9 August, 2005 School of Physics, 1 p.m., Room 5 Abstract
In some magnetic insulators, so-called "spin-liquids", the elementary excitations carry a spin s=1/2 (spinon), that is a fraction of the spin carried by the local degrees of freedom (a spin flip can only change the magnetization by + or -1). While this phenomenon of fractionalization is rather simple to understand in one-dimension, the situation is more involved for two and three-dimensional systems. In this talk I will attempt to review some of the (simplest) ideas in the field, and to show in particular that gauge theories offer a natural language to address the question of confinement and deconfinement of spinons in quantum spin models.
