Invited Speaker / Conférencier invité

In 1958, Phil Anderson showed that the wavefunctions of noninteracting particles moving in a random potential can become localized in space. Anderson localization has since been observed in a wide variety of systems. However, interactions between particles aren’t always negligible. In fact it is precisely the materials in which electron-electron interactions are most significant that are of...

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Invited Speaker / Conférencier invité

Band theory and BCS theory are arguably the most successful theories of condensed matter. Yet, both of them fail miserably for high-temperature cuprate superconductors and layered organic superconductors. New theoretical methods are required. In this talk, I compare experiment in cuprates and layered organics with theoretical results obtained from extensions of dynamical mean-field theory for...

Electrons in metals move around and they interact with one another via the Coulomb interaction. When electrons form extended (i.e. Bloch) states they do the same thing. Yet very often they form a collective exotic state like superconductivity. Is this the consequence of pairing via an attractive interaction, or is something more subtle at work? This talk will discuss what is currently not...
