摘要：

We show that a 2D system of free electrons on a square lattice with hoping between more than nearest neighbours is characterised by two quantum critical points associated with a change in topology of Fermi surface as a function of electron concentration. This simple model (when taking into account a positive interaction in a triplet channel) allows us to consistently explain some crucial experiments in the underdoped regime of hole-doped high T-c cuprates (ARPES, neutron scattering).
