Disordered Flat Phase and Phase Diagram for Restricted Solid on Solid Models of Fcc(110) Surfaces
G. Santoro, M. Vendruscolo, S. Prestipino +1
We discuss the results of a study of restricted solid-on-solid models for fcc (110) surfaces. These models are simple modifications of the exactly solvable BCSOS model, and are abl…
Phase Diagram of a Model of Correlated Hopping of Electrons in a Lattice of Berry Molecules
Giuseppe Santoro, Nicola Manini, Alberto Parola +1
The phase diagram of a model for correlated hopping of electrons in a lattice of Berry phase molecules is presented. Electrons hop in presence of an extra orbital degree of fr…
Preroughening, Diffusion, and Growth of An FCC(111) Surface
S. Prestipino, G. Santoro, E. Tosatt
Preroughening of close-packed fcc(111) surfaces, found in rare gas solids, is an interesting, but poorly characterized phase transition. We introduce a restricted solid-on-solid mo…
