Attosecond science is based on electron dynamics driven by a strong optical electric field
and has evolved beyond its original scope in gas-phase atomic and molecular physics to …

When an ultrashort laser pulse irradiates a metal, energy is absorbed by the electron system
which is driven out of thermal equilibrium on a femtosecond time scale. Due to electron …

Nonlinear photoelectron emission from metallic nanotips is explored in the strong-field
regime. The passage between the multiphoton and the optical field emission regimes is …

The problem of highly nonlinear photoemission from a metal surface is considered using
analytical and numerical approaches. Descriptions are found which cover both the weak …

Recent studies of the performance of radio-frequency (rf) copper cavities operated at
cryogenic temperatures have shown a dramatic increase in the maximum achievable …

This paper studies photoelectron emission from metal surfaces with laser wavelengths from
200 to 1200 nm (ie, ultraviolet to near-infrared), using a recent quantum model based on the …

In this Letter we report on the use of ultrashort infrared laser pulses to generate a copious
amount of electrons by a copper cathode in an rf photoinjector. The charge yield verifies the …

Metal photocathodes are an important source of high-brightness electron beams, ubiquitous
in the operation of both large-scale accelerators and table-top microscopes. When the …

Strongly coupled plasmons in a system of individual gold nanoparticles placed at
subnanometer distance to a gold film (nanoparticle-on-plane, NPOP) are investigated using …

Field emission of electrons is generated solely by the ultrastrong near-field of strongly
coupled plasmons without the help of a noticeable dc field. Strongly coupled plasmons are …
