Non-Tomonaga-Luttinger-Liquid Behavior of the Ground State of Model One-Dimensional Electron Systems

抄録

An asymptotically exact ground-state wave function is obtained for one-dimensional electrons of a model Hamiltonian. The Hamiltonian has an arbitrary parameter. Tomonaga-Luttinger (TL)-liquid-like behavior for a small value of the parameter changes gradually into non-TL-liquid behavior as the parameter is increased. Parameter dependence of the momentum distribution function and the structure factor are investigated numerically for small systems.
