The dark energy scalar eld is here presented as a mean-eld eect arising from the
collective motion of interacting structures on an expanding lattice. This cosmological
analogue to solid-state soft phonons in an unstable crystal network is shown to produce
cosmic acceleration while mimicking phantom equation of state.
