The stripes of the high Tc superconductors
  KTH/Nordita/SU seminar in Theoretical Physics [before December 2013]

Friday 25 May 2007
from 11:00 to 12:00
at FB41
Speaker : Jan Zaanen (Leiden University)
Abstract : 'Stripes' code for a peculiar electronic ordering phenomenon generic in doped Mott-insulator. After a long history of controversy these are now generally recognized as the main competitor of superconductivity in the cuprate superconductors. I will tell the story from a historical and subjective viewpoint: how it all started by an accidental discovery by a young theorist on a friday afernoon in 1987; how the idea inspired a brilliant experimentalist to start to dig in a place where nobody dared to go; how the stripes turned magically into guinea pigs for completely novel modes of experimentation to probe strongly interacting quantum matter, culminating in Abbamonte's synchrotron experiments and the Mott-maps of Davis et al.; why the idea of stripe quantum liquids is very much alive but still controversial; why one has to grasp some strange duality transformations in order to understand what has to be done in order to nail down these quantum stripes experimentally.
