Alkali Halide Surfaces Near Melting: Wetting and Nanofriction Properties
D. Ceresoli, T. Zykova-Timan, U. Tartaglino +1
Alkali halide (100) crystal surfaces are poorly wetted by their own melt at the triple point. We carried out simulations for NaCl(100) within the well tested BMHFT model potential.…
Electron corrected Lorentz forces in solids and molecules in magnetic field
D. Ceresoli, R. Marchetti, E. Tosatti
We describe the effective Lorentz forces on the ions of a generic insulating system in an magnetic field, in the context of Born-Oppenheimer ab-initio molecular dynamics. The force…
Peak Effect versus Skating in High Temperature Nanofriction
T. Zykova-Timan, D. Ceresoli, E. Tosatti
The physics of sliding nanofriction at high temperature near the substrate melting point $\Tmelt$ is so far unexplored. We conducted simulations of hard tips sliding on a prototype…
Triangular Mott-Hubbard Insulator Phases of Sn/Si(111) and Sn/Ge(111) Surfaces
G. Profeta, E. Tosatti
The ground state of Sn/Si(111) and Sn/Ge(111) surface -phases is reexamined theoretically, based on calculations where correlations are approximately included throug…
Gold Clusters Sliding on Graphite: a Possible Quartz Crystal Microbalance Experiment?
Stoyan Pisov, Erio Tosatti, Ugo Tartaglino +1
A large measured 2D diffusion coefficient of gold nanoclusters on graphite has been known experimentally and theoretically for about a decade. When subjected to a lateral force, th…
