Study of pseudogap in underdoped cuprate
Ping Lou, Hang-sheng Wu
Abstract
A mean field SDW analysis of pseudogap in the underdoped cuprates is proposed on the basis of the t-t-U Hubbard model. The prediction of our theory is consistent with the experiment quite well within the uncertainty of the present experimental measurement. Therefore we argue that the pseudogap phenomenon in the underdoped cuprates can be well explained within the mean field approximation.
