SUMMARY:Effect of order parameter fluctuations on the spectral density
  in d-wave superconductors\, R. G. Herb Condensed Matter Seminar\, Max
 im Khodas\, Brookhaven National Laboratory
DESCRIPTION:My talk contains two related parts. In the first part I wi
 ll discuss the spectral density in 2D d-wave superconductors in the re
 gime of strong quantum fluctuations. I will start with the motivation 
 based on Angular Resolved Photo-Emission Experiments. The theoretical 
 model is then presented to capture the effects of phase fluctuations w
 ithout specifying the (unknown) paring mechanism. I discuss the soluti
 on of the model and give results for the spectral function. In the sec
 ond part I will discuss the Fermi Surface Reconstruction and underlyin
 g mechanism related to the anti-ferromagnetic fluctuations. I will sho
 w how the pockets obtained on the mean field level are modified by the
  fluctuations of the staggered magnetization. Finally\, I would conclu
 de with a short summary.
