Some aspects of the linear chain of harmonic oscillators (“harmonic liquid”) are studied. In particular we compute the stationary correlation functions of coordinates and momenta of the oscillators for a particular non-equilibrium steady state. We find that the coordinates and momenta...

Our previous work in which we have computed the stationary correlation functions of positions and momenta in the “harmonic liquid” is now extended to get the expressions of the time-dependent correlation functions of such quantities. The static and dynamic structure factors are computed. The...
