Description
We present an overview of the field-theoretical renormalzation group
approach for interacting electrons in the normal phase of the optimally
doped cuprates. Earlier calculations predicted the existence of d-wave
charge density instabilities(d-CDW) which were later verifed in several
experiments in non-Lanthanum materials. However the onset of the so-called
pseudogap state remains an open problem to this date. We will discuss some
alternatives for this riddle
