"Theory of the Universal Aspects of the Phase Diagram of Cuprates"

Presented by Chandra Varma, University of California- Riverside

Thursday, April 3, 2008, 1:30 pm — Small Seminar Room, Bldg. 510

Abstract: Experiments in the last few years have confirmed that time- reversal symmetry and inversion are broken in the underdoped region of the phase diagram of the Cuprates, which ends at a quantum critical point in the superconducting dome. Quantum critical fluctuations of this phase have been derived to have the form hypothesized to explain the properties of the Strange Metal or Marginal Fermi-liquid region of the phase diagram. Especially important are the predicted spectral functions revealed by ARPES at Brookhaven and elsewhere. It is now shown that the coupling of fluctuations to the fermions leads to attractive interaction among them in the d-wave channel.
