abstract = {We present a three-lane exclusion process that exhibits the
same universal fluctuation pattern as generic
one-dimensional Hamiltonian dynamics with short-range
interactions, viz., with two sound modes in the
Kardar-Parisi-Zhang (KPZ) universality class (with dynamical
exponent z=3/2 and symmetric Prähofer-Spohn scaling
function) and a superdiffusive heat mode with dynamical
exponent z=5/3 and symmetric Lévy scaling function. The
lattice gas model is amenable to efficient numerical
simulation. Our main findings, obtained from dynamical
Monte-Carlo simulation, are: (i) The frequently observed
numerical asymmetry of the sound modes is a finite time
effect. (ii) The mode-coupling calculation of the scale
factor for the 5/3-Lévy-mode gives at least the right order
of magnitude. (iii) There are significant diffusive
corrections which are non-universal.},
