Surprises in the Orbital Magnetic Moment and g-Factor of the Dynamic Jahn-Teller Ion C_{60}^-
Erio Tosatti, Nicola Manini, Olle Gunnarsson
We calculate the magnetic susceptibility and g-factor of the isolated C_{60}^- ion at zero temperature, with a proper treatment of the dynamical Jahn-Teller effect, and of the asso…
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…
The Phase Diagram of Correlated Electrons in a Lattice of Berry Molecules
Giuseppe Santoro, Marco Airoldi, Nicola Manini +2
A model for correlated electrons in a lattice with local additional spin--1 degrees of freedom inducing constrained hopping, is studied both in the low density limit and at quarter…
Enhanced Electron Pairing in a Lattice of Berry Phase Molecules
N. Manini, E. Tosatti, S. Doniach
We show that electron hopping in a lattice of molecules possessing a Berry phase naturally leads to pairing. Our building block is a simple molecular site model inspired by C$_{60}…
Electron--Vibron Interactions in Charged Buckminsterfullerene: Pair Energies and Spectra (Part II)
Nicola Manini, Erio Tosatti, Assa Auerbach
The ground state energy shifts and excitation spectra of charged buckminsterfullerene C, are calculated. The electron--vibron Hamiltonian of Part I is ex…
The (001) surface of alpha-Ga is covered with GaIII
M. Bernasconi, G. L. Chiarotti, E. Tosatti
We propose, based on ab initio calculations, that the ground state (001) surface of -Ga should be covered by two layers of GaIII, a denser phase which is stable in the bulk only…
