    "abstract": "Transient pump-probe optical reflectivity measurements of the\nnano/microsecond dynamics of a fully reversible, light-induced,\nsurface-assisted metallization of gallium interfaced with silica are reported.\nThe metallization leads to a considerable increase in the interface\u0027s\nreflectivity when solid a-gallium is on the verge of melting. The reflectivity\nchange was found to be a cumulative effect that grows with light intensity and\npulse duration. The reflectivity relaxes back to that of alpha-gallium when the\nexcitation is withdrawn in a time that increases critically at gallium\u0027s\nmelting point. The effect is attributed to a non-thermal light-induced\nstructural phase transition.",
