 Title: Nonequilibrium stationary states of harmonic chains with bulk noises Author: Bernardin, Cedric; Kannan, Venkateshan; Lebowitz, Joel L.; Lukkarinen, Jani Contributor organization: Department of Mathematics and StatisticsMathematical physics Date: 2011 Language: eng Number of pages: 5 Belongs to series: European Physical Journal B. Condensed Matter and Complex Systems ISSN: 1434-6028 DOI: https://doi.org/10.1140/epjb/e2011-20746-0 URI: http://hdl.handle.net/10138/29106 Abstract: We consider a chain composed of $N$ coupled harmonic oscillators in contact with heat baths at temperature $T_\ell$ and $T_r$ at sites 1 and $N$ respectively. The oscillators are also subjected to non-momentum conserving bulk stochastic noises. These make the heat conductivity satisfy Fourier's law. Here we describe some new results about the hydrodynamical equations for typical macroscopic energy and displacement profiles, as well as their fluctuations and large deviations, in two simple models of this type.
