摘要：

A modified Hubbard alloy analogy leads to an equation for the proper self-energy of the Hubbard model at T = 0 which yields exact results in certain limits and has a series solution in powers of the interaction U satisfying Luttinger's requirements. However, Fermi liquid behaviour breaks down in a region of the phase diagram where the series diverges, although it persists for all U at sufficiently low electron density. © 1990.
