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…
A simulation study of energy transport in the Hamiltonian XY-model
Luca Delfini, Stefano Lepri, Roberto Livi
The transport properties of the planar rotator model on a square lattice are analyzed by means of microcanonical and non--equilibrium simulations. Well below the Kosterlitz--Thoule…
Stretched--exponential relaxation in arrays of coupled rotators
Maria Eleftheriou, Stefano Lepri, Roberto Livi +1
We consider the non--equilibrium dynamics of a chain of classical rotators coupled at its edges to an external reservoir at zero temperature. We find that the energy is released in…
