First-order microcanonical transitions in finite mean-field models
Mickael Antoni, Stefano Ruffo, Alessandro Torcini
A microcanonical first order transition, connecting a clustered to a homogeneous phase, is studied from both the thermodynamic and dynamical point of view for a N-body Hamiltonian…
Thermally activated processes in polymer dynamics
Lorenzo Bongini, Roberto Livi, Alessandro Torcini +1
Jumps between neighboring minima in the energy landscape of both homopolymeric and heteropolymeric chains are numerically investigated by determining the average escape time from d…
Doppler Effect of Nonlinear Waves and Superspirals in Oscillatory Media
Lutz Brusch, Alessandro Torcini, Markus Baer
Nonlinear waves emitted from a moving source are studied. A meandering spiral in a reaction-diffusion medium provides an example, where waves originate from a source exhibiting a b…
Coarsening process in one-dimensional surface growth models
Alessandro Torcini, Paolo Politi
Surface growth models may give rise to unstable growth with mound formation whose tipical linear size L increases in time. In one dimensional systems coarsening is generally driven…
A dynamical approach to protein folding
Alessandro Torcini, Roberto Livi, Antonio Politi
In this paper we show that a dynamical description of the protein folding process provides an effective representation of equilibrium properties and it allows for a direct investig…
Coarsening in surface growth models without slope selection
Paolo Politi, Alessandro Torcini
We study conserved models of crystal growth in one dimension [] which are linearly unstable and develop a mound structure whose typical size…
