Phys. Rev. Lett. 70, 3780–3783 (1993)Generalized hard-core fermions in one dimension: An exactly solvable Luttinger liquidSee Also: Erratum Received 1 April 1993; published in the issue dated 14 June 1993 A model for interacting spinless fermions in one dimension is presented and solved exactly. The solution is shown to be a Luttinger liquid with charge density wave instabilities for well characterized filling factors. Under very plausible assumptions, the exact solution is extended to the spin case with the usual charge-spin separation into two different Luttinger liquids. Required technicalities are almost trivial but the solution is very rich: Periodicity of instabilities and correlation exponents can be chosen at will. © 1993 The American Physical Society URL:
