    "abstract": "Self-consistent simulations of the ultrafast electron dynamics in thin metal\nfilms are performed. A regime of nonlinear oscillations is observed, which\ncorresponds to ballistic electrons bouncing back and forth against the film\nsurfaces. When an oscillatory laser field is applied to the film, the field\nenergy is partially absorbed by the electron gas. Maximum absorption occurs\nwhen the period of the external field matches the period of the nonlinear\noscillations, which, for sodium films, lies in the infrared range. Possible\nexperimental implementations are discussed.",
