Solitons and exact velocity quantization of incommensurate sliders
Nicola Manini, Marco Cesaratto, Giuseppe E. Santoro +2
We analyze in some detail the recently discovered velocity quantization phenomena in the classical motion of an idealized one-dimensional solid lubricant, consisting of a harmonic…
Asymmetric frictional sliding between incommensurate surfaces
Giuseppe E. Santoro, Andrea Vanossi, Nicola Manini +2
We study the frictional sliding of two ideally incommensurate surfaces with a third incommensurate sheet - a sort of extended lubricant - in between. When the mutual ratios of the…
Exactly quantized dynamics of classical incommensurate sliders
Andrea Vanossi, Nicola Manini, Giorgio Divitini +2
We report peculiar velocity quantization phenomena in the classical motion of an idealized 1D solid lubricant, consisting of a harmonic chain interposed between two periodic slider…
Physics and Nanofriction of Alkali Halide Solid Surfaces at the Melting Point
T. Zykova-Timan, D. Ceresoli, U. Tartaglino +1
Alkali halide (100) surfaces are anomalously poorly wetted by their own melt at the triple point. We carried out simulations for NaCl(100) within a simple (BMHFT) model potential.…
Electron-Stimulated Emission of Na Atoms from NaCl Nanocube Corners
D. Ceresoli, T. Zykova-Timan, E. Tosatti
We performed first principles density functional calculations and simulations of magic-size neutral NaCl nanocubes, and computed the the extraction of a Na neutral corner atom afte…
Ballistic Conductance and Magnetism in Short Tip-Suspended Ni Nanowires
A. Smogunov, A. Dal Corso, E. Tosatti
Electronic and transport properties of a short Ni nanowire suspended between two semi-infinite ferromagnetic Ni leads are explored in the framework of density-functional theory. Th…
