Description
We study a one-dimensional chain of masses connected by harmonic springs and subject to dry friction. The problem at the heart of our study is whether, in this sytem, the statistical properties of the configurations explored by an athermal driving mechanism can be reproduced by an effective equilibrium theory. In this seminar I present an effective theory for the harmonic chain with friction which can be exactly solved using transfer matrices and I compare its predictions with the results from numerical simulations.
