T4-7 Fluctuations and Disorder in Condensed Matter (DCMMP) | Fluctuations et désordre en matière condensée (DPMCM)
- Erik Sorensen (McMaster University)
Geometrically frustrated magnets form a broad class of materials where competing interactions lead to the partial or complete suppression of classical magnetic order. While short-range magnetic correlations exist in the absence of long-range order, these systems remain disordered and fluctuating, exploring a largely degenerate and complex energy landscape. Such state is commonly named a spin...
In conventional metals like aluminum or copper, the behaviour of electrons is well described by traditional methods of solid state physics. However, these methods cannot be used to study strongly correlated materials in which the interactions between electrons are significant. It instead becomes important to take into account large classical and quantum fluctuations. This is the case in the...
Many two-dimensional physical systems, ranging from atomic-molecular condensates to low-dimensional superconductors and liquid crystal films, are described by coupled XY models. The interplay of topology and competing interactions in these XY systems drives new kinds of emergent behavior relevant in both quantum and classical settings. Such coupled U(1) systems further introduce rich physics,...
