Query: Exploring canyons in glassy energy landscapes using metadynamics   The complex physics of glass forming systems is controlled by the structure
of the low energy portions of their potential energy landscapes. Here, we
report that a modified metadynamics algorithm efficiently explores and samples
low energy regions of such high-dimensional landscapes. In the energy landscape
for a model foam, metadynamics finds and descends meandering `canyons' in the
landscape, which contain dense clusters of energy minima along their floors.
Similar canyon structures in the energy landscapes of two model glass
formers--hard sphere fluids and the Kob-Andersen glass--allow metadynamics to
reach low energies. In the hard sphere system, fluid configurations are found
to form continuous regions that cover the canyon floors, but only up to a
volume fraction close to that predicted for kinetic arrest. For the
Kob-Andersen glass former, metadynamics reaches the canyons' ends with modest
computational effort; with the lowest energies found approaching the predicted
Kauzmann limit.
