29 March 2007 FWN-Building 5111.0080, Nijenborgh 4, 9747 AG, Groningen
Speaker: Prof. dr. Jan Zaanen
Affiliation: Leiden University: Lorentz Institute for Theoretical Physics
Title: Twenty years of high Tc superconductivity

Start: 16.00
Location: FWN-Building 5111.0080


The subject of high Tc superconductivity was born in an un-precedented hype in the late 1980's. Despite this bad start it has evolved into what is seen by many as the most profound mystery in quantum condensed matter physics. I will try to get across the obsessive powers of this problem, emphasizing aspects which are particularly dear to my person: the quantum stripe liquid at low dopings (see figure); the unreasonable simplicity of the metallic state  at optimal doping showing the remarkable Planckian dissipation; why this should be rooted in fermionic quantum criticality, and why there are reasons to believe in quantum number fractionalization.
