Crossover from Fermi Liquid to Non-Fermi Liquid Behavior in a Solvable One-Dimensional Model
Y. Chen, K. A. Muttalib
Abstract
We consider a quantum moany-body problem in one-dimension described by a Jastrow type, characterized by an exponent λ and a parameter γ. We show that with increasing γ, the Fermi Liquid state (γ=0) crosses over to non-Fermi liquid states, characterized by effective "temperature".
