The mechanism of high temperature superconductivity and the so-called pseudogap phase in the cuprate materials has yet to be settled. This talk will focus on the mysterius pseudogap problem; is it a precursor to superconductivity or a competing phase? The Nernst effect being extremely sensitive to both electronic transformations and superconducting fluctuations is therefore a powerfull and important technique in the study of the pseudogap phase. We will present new Nernst effect data on underdoped cuprates and discuss the nature of the superconducting flucutuations in the cuprates. Are these predominately phase or amplitude fluctuations and what is the relation to the pseudogap phase? These are questions that will be addressed.
