Study of the induced potential produced by ultrashort pulses on metal surfaces

The relevance of the induced potential for photoelectron emission from metal surfaces resulting from grazing-incidence ultrashort laser pulses is studied. To describe this process we introduce a distorted-wave method, which includes the perturbation on the emitted electron produced by both the laser...
