Exploring the energy landscape of model proteins: a metric criterion for the determination of dynamical connectivity
Lorenzo Bongini, Roberto Livi, Antonio Politi +1
A method to reconstruct the energy landscape of small peptides is presented with reference to a 2d off--lattice model. The starting point is a statistical analysis of the configura…
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…
Nonlinear Analysis of the Eckhaus Instability: Modulated Amplitude Waves and Phase Chaos with Non-zero Average Phase Gradient
Lutz Brusch, Alessandro Torcini, Markus Baer
We analyze the Eckhaus instability of plane waves in the one-dimensional complex Ginzburg-Landau equation (CGLE) and describe the nonlinear effects arising in the Eckhaus unstable…
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…
