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…
Role of Layering Oscillations at Liquid Metal Surfaces in Bulk Recrystallization and Surface Melting
Orio Tomagnini, Furio Ercolessi, Simonetta Iarlori +2
The contrasting melting behavior of different surface orientations in metals can be explained in terms of a repulsive or attractive effective interaction between the solid-liquid a…
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…
Dynamical Jahn-Teller Effect and Berry Phase in Positively Charged Fullerene I. Basic Considerations
P. De Los Rios, N. Manini, E. Tosatti
We study the Jahn-Teller effect of positive fullerene ions C and C. The aim is to discover if this case, in analogy with the negative ion, possesses…
Surface States, Surface Metal-Insulator, and Surface Insulator-Metal Transitions
E. TOSATTI
I present an informal discussion of various cases where two-dimensional surface metal-insulator structural and charge-density-wave instabilities driven by partly filled surface sta…
