Cuprate Workshop 2008

The ICAM-CNAM Workshop on Cuprate Fermiology was held at the University of Maryland on Friday Nov. 14 and Saturday Nov. 15, 2008. The workshop was motivated by the recent observations of quantum oscillations in YBCO (ortho-II YBa2Cu3O6.5 and YBa2Cu4O8) which have suggested the occurrence of small Fermi surface pockets in the underdoped cuprates. About 50 researchers were brought together to review the status of these experiments and to assess their implications within the framework of theoretical cuprate physics and the large body of other experimental data on the cuprates. The workshop featured invited talks with much open discussion and a poster session. The presentations are listed below with links to the slides if available.
