摘要：
Recent photoemission and thermodynamic experiments on underdoped cuprates strikingly confirm the prediction that the pseudogap is driven by a splitting of the degeneracy of the Van Hove singularity. The doping dependence of the pseudogap can be understood in terms of a crossover from magnetic to charge-dominated behavior (including strong electron-phonon coupling). The crossover is accompanied by a nanoscale phase separation (striped phase), which is shown to be driven by Van Hove nesting.
