Reply to Dhar's comment on "Can disorder induce a finite thermal conductivity in 1D lattices"

Original · EN

In his comment, Dhar (cond-mat/0106349) claims that the existence and uniqueness of a nonequilibrium stationary state has been proved by Lebowitz et al. We should point out that our observation does not contradict the proof. They have only proved that when a (mass) disordered harmonic chain is placed in contact with stochastic reservoirs of the Langevin type, a nonequilibrium stationary state can be reached. However, they didn't prove the existence and uniqueness of the nonequilibrium stationary state for the general case, namely, when the chain is in contact with general thermostated reservoirs (see Bonneto et al. math-ph/0002052).
