Interface pinning and slow ordering kinetics on infinitely ramified fractal structures
Umberto Marini Bettolo Marconi
We investigate the time dependent Ginzburg-Landau (TDGL) equation for a non conserved order parameter on an infinitely ramified (deterministic) fractal lattice employing two altern…
Dynamic Density Functional Theory of Fluids
Umberto Marini Bettolo Marconi, Pedro Tarazona
We present a new time-dependent Density Functional approach to study the relaxational dynamics of an assembly of interacting particles subject to thermal noise. Starting from the L…
A kinetic approach to granular gases
A. Puglisi, V. Loreto, U. Marini Bettolo Marconi +1
We address the problem of the so-called ``granular gases'', i.e. gases of massive particles in rapid movement undergoing inelastic collisions. We introduce a class of models of dri…
Phase separation in systems with absorbing states
M. A. Munoz, U. Marini Bettolo Marconi, R. Cafiero
We study the problem of phase separation in systems with a positive definite order parameter, and in particular, in systems with absorbing states. Owing to the presence of a single…
Measurements of the reaction of antiproton annihilation at rest at three hydrogen target densities
OBELIX Collaboration, V. Alberico, A. Bertin
The proton-antiproton annihilation at rest into the final state was measured for three different target densities: liquid hydrogen, gaseous hydrogen at NTP and at a low pressu…
Critical properties of Ising model on Sierpinski fractals. A finite size scaling analysis approach
J. M. Carmona, U. Marini Bettolo Marconi, J. J. Ruiz-Lorenzo +1
The present paper focuses on the order-disorder transition of an Ising model on a self-similar lattice. We present a detailed numerical study, based on the Monte Carlo method in co…
