Dynamics of liquid He-4 in confined geometries from Time-Dependent Density Functional calculations
Luigi Giacomazzi, Flavio Toigo, Francesco Ancilotto
We present numerical results obtained from Time-Dependent Density Functional calculations of the dynamics of liquid He-4 in different environments characterized by geometrical conf…
Acetylene on Si(100) from first principles: adsorption geometries, equilibrium coverages and thermal decomposition
Pier Luigi Silvestrelli, Flavio Toigo, Francesco Ancilotto
Adsorption of acetylene on Si(100) is studied from first principles. We find that, among a number of possible adsorption configurations, the lowest-energy structure is a ``bridge''…
Wetting transitions of He4 on alkali metal surfaces from density functional calculations
Francesco Ancilotto, Fabio Faccin, Flavio Toigo
We have studied the wetting properties of He4 adsorbed on the surface of heavy alkali metals by using a non-local free-energy density-functional which describes accurately the surf…
Adsorption of benzene on Si(100) from first principles
Pier Luigi Silvestrelli, Francesco Ancilotto, Flavio Toigo
Adsorption of benzene on the Si(100) surface is studied from first principles. We find that the most stable configuration is a tetra--bonded structure characterized by one C-C d…
Prewetting transitions of Ar and Ne on alkali metal surfaces
Francesco Ancilotto, Flavio Toigo
We have studied by means of Density-Functional calculations the wetting properties of Ar and Ne adsorbed on a plane whose adsorption properties simulate the Li and Na surfaces. We…
A Real-Space Full Multigrid study of the fragmentation of Li11+ clusters
Francesco Ancilotto, Philippe Blandin, Flavio Toigo
We have studied the fragmentation of Li11+ clusters into the two experimentally observed products (Li9+,Li2) and (Li10+,Li) The ground state structures for the two fragmentation ch…
Wetting of Argon on CO2
Giampaolo Mistura, Francesco Ancilotto, Lorenzo Bruschi +1
We have studied the wetting transition of Ar adsorbed on solid CO2 by means of high-precision adsorption isotherms measured with a quartz microbalance. We observe triple-point wett…
Stochastic Growth Equations and Reparametrization Invariance
M. Marsili, A. Maritan, F. Toigo +1
It is shown that, by imposing reparametrization invariance, one may derive a variety of stochastic equations describing the dynamics of surface growth and identify the physical pro…
Fluctuation Dissipation Theorem and The Dynamical Renormalization Group
Achille Giacometti, Amos Maritan, Flavio Toigo +1
The relation between a recently introduced dynamical real space renormalization group and the fluctuation-dissipation theorem is discussed. An apparent incompatibility is pointed o…
Real Space Renormalization Group for Langevin Dynamics in Absence of Translational Invariance
Achille Giacometti, Amos Maritan, Flavio Toigo +1
A novel exact dynamical real space renormalization group for a Langevin equation derivable from a Euclidean Gaussian action is presented. It is demonstrated rigorously that an alge…
