"Phase transitions beyond the Landau-Ginzburg theory"
 Slideshow (PDF)

Critical behavior and phase transitions are of great interest in condensed matter physics. In this talk we introduce the basic concepts about criticality, as well as theoretical and numerical tools to study critical phenomena. The Landau-Ginzburg theory, or the "Order parameter" picture has been successful in describing many systems with second order phase transitions, for example in superconductors. But here we'll also see a 2D modified XY model that has phase transitions that doesn't not fit into the traditional description.


* Refreshments will be available at the talk.
