Stochastic dynamics of a sheared granular medium
Alberto Petri, Andrea Baldassarri, Fergal Dalton +3
We experimentally investigate the response of a sheared granular medium in a Couette geometry. The apparatus exhibits the expected stick-slip motion and we probe it in the very int…
Heat wave propagation in a nonlinear chain
F. Piazza, S. Lepri
We investigate the propagation of temperature perturbations in an array of coupled nonlinear oscillators at finite temperature. We evaluate the response function at equilibrium and…
From the conserved Kuramoto-Sivashinsky equation to a coalescing particles model
Paolo Politi, Daniel ben-Avraham
The conserved Kuramoto-Sivashinsky (CKS) equation, u_t = -(u+u_xx+u_x^2)_xx, has recently been derived in the context of crystal growth, and it is also strictly related to a simila…
Free energy landscape of mechanically unfolded model proteins: extended Jarzinsky versus inherent structure reconstruction
Stefano Luccioli, Alberto Imparato, Alessandro Torcini
The equilibrium free energy landscape of off-lattice model heteropolymers as a function of an internal coordinate, namely the end-to-end distance, is reconstructed from out-of-equi…
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…
