Invited Speaker / Conférencier invité
Strongly interacting electron systems have fascinated the condensed matter community for a few decades. The addition of interactions to a model leads, in many cases, to new kinds of states, especially in low dimensional systems where fluctuations are pronounced. Notable examples are unconventional superconductivity and the fractional quantum Hall effect.
Spin orbit coupling, on the other...

Invited Speaker / Conférencier invité
Topological insulators are recently discovered states of matter that are electrically insulating in the bulk but support novel conducting boundary states that are exceptionally robust to perturbations. The physics of topological insulators is due to strong spin-orbit coupling and, despite its exotic character, is well understood in a single-particle picture where electron-electron interactions...

Invited Speaker / Conférencier invité
Recent years have witnessed the unexpected discovery of novel topological phases in certain electrically insulating and semimetallic solids whose low-energy bulk excitations are Dirac fermions.
Topological phases in these ‘‘Dirac materials’’ are characterized
by nonzero integers (topological invariants), which
manifest themselves through peculiar and robustly gapless
states localized at...
