The collision rate ansatz for the classical Toda lattice
arXiv:2004.03802 · doi:10.1103/PhysRevE.101.060103
Abstract
Considered is a generalized Gibbs ensemble of the classical Toda lattice. We establish that the collision rate ansatz follows from (i) the charge-current susceptibility matrix is symmetric and (ii) the stretch current is proportional to the momentum, hence conserved.
