Antiferromagnetic fluctuations in the one-dimensional Hubbard model
Original language description
We use a mean-field-type approximation with a two-particle self-consistency renormalizing the bare interaction to study the low-temperature critical behavior of the one-dimensional Hubbard model near half filling caused by enhanced antiferromagnetic fluctuations. We show that there is a crossover temperature $T_{0}= texp{-1/U ρ(0)}$ below which goes over to strong coupling and approaches a quantum critical point with the diverging staggered susceptibility and a gap in the excitation spectrum at zero temperature.
