Abstract


We show the breakdown of the Fermi-like features in one-dimensional (1D) impenetrable Bosons with attractive interaction[1]. The 1D impenetrable Boson system is displayed by using the restricted solid-on-solid (RSOS) model with the point-contact-type step-step attraction. The RSOS model is called a p-RSOS model. The transfer matrix, which is formed by a 19-vertex model equivalent to the p-RSOS model, connects the surface system and the 1D Boson system.
