Stochastic dynamics of model proteins on a directed graph
L. Bongini, L. Casetti, R. Livi +2
A method for reconstructing the energy landscape of simple polypeptidic chains is described. We show that we can construct an equivalent representation of the energy landscape by a…
Nonequilibrium Invariant Measure under Heat Flow
L. Delfini, S. Lepri, R. Livi +1
We provide an explicit representation of the nonequilibrium invariant measure for a chain of harmonic oscillators with conservative noise in the presence of stationary heat flow. B…
Multiple timescales in a model for DNA denaturation dynamics
Marco Baiesi, Roberto Livi
The denaturation dynamics of a long double-stranded DNA is studied by means of a model of the Poland-Scheraga type. We note that the linking of the two strands is a locally conserv…
Anomalous transport and relaxation in classical one-dimensional models
G. Basile, L. Delfini, S. Lepri +3
After reviewing the main features of anomalous energy transport in 1D systems, we report simulations performed with chains of noisy anharmonic oscillators. The stochastic terms are…
