Abstract

A recent experiment which measured the Nernst effect, the diamagnetic signal and the H c2 field was interpreted as a support to the scenario which the pseudogap has the pair condensate without long-range phase coherence. We present here calculations which qualitatively reproduces the onset of the Nernst signal temperature T ν (ρ) and T c (ρ) as function of the doping level ρ. Together with our previous calculations to the magnetization and H c2, we conclude that the phase separation scenario supports also the new Nernst effect experiments.
