|Title:||Twenty years of high Tc superconductivity|
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.
