Two emerging areas of research, attosecond and nanoscale physics, have recently started to merge. Attosecond physics deals with phenomena occurring when ultrashort laser pulses, with duration on the femto- and sub-femtosecond time scales, interact with atoms, molecules or solids. The laser-induced electron dynamics occurs natively on a timescale down to a few hundred or even tens of attoseconds (1 attosecond=1 as=10$^{-18}$ s), which is of the order of the optical field cycle. For comparison…

Summary form only given. Fundamental processes in atoms, molecules, as well as condensed matter are triggered or mediated by the motion of electrons inside or between atoms. Electronic dynamics on

Attosecond control of electrons emitted from a nanoscale metal tip

TLDR
The results indicate that the attosecond techniques developed with atoms and molecules can also be used with solids, and foresee subfemtosecond, subnanometre probing of collective electron dynamics in solid-state systems ranging in scale from mesoscopic solids to clusters and to single protruding atoms.

Attosecond spectroscopy in condensed matter

TLDR
The ability to obtain direct time-domain access to charge dynamics with attosecond resolution by probing photoelectron emission from single-crystal tungsten is demonstrated and illustrates thatAttosecond metrology constitutes a powerful tool for exploring not only gas-phase systems, but also fundamental electronic processes occurring on the attose Cond timescale in condensed-matter systems and on surfaces.

Imaging ultrafast molecular dynamics with laser-induced electron diffraction

TLDR
The method has the sensitivity to measure a 0.1 Å displacement in the oxygen bond length occurring in a time interval of ∼5 fs, which establishes LIED as a promising approach for the imaging of gas-phase molecules with unprecedented spatio-temporal resolution.

Attosecond metrology

TLDR
The demonstrated experimental tools and techniques open the door to attosecond spectroscopy of bound electrons by using a subfemtosecond soft-X-ray pulse and a few-cycle visible light pulse to trace electronic dynamics with a time resolution of ≤ 150 as.

Temporal broadening of attosecond photoelectron wavepackets from solid surfaces

The response of solids to electromagnetic fields is of crucial importance in many areas of science and technology. Many fundamental questions remain to be answered about the dynamics of the

Ultrafast electron dynamics in phenylalanine initiated by attosecond pulses

TLDR
The application of isolated attosecond pulses to prompt ionization of the amino acid phenylalanine and the subsequent detection of ultrafast dynamics on a sub–4.5-femtosecond temporal scale, which is shorter than the vibrational response of the molecule.

Attosecond chronoscopy of photoemission

Recent advances in the generation of well characterized sub-femtosecond laser pulses have opened up unpredicted opportunities for the real-time observation of ultrafast electronic dynamics in matter.

Attosecond nanoplasmonic streaking of localized fields near metal nanospheres

Collective electron dynamics in plasmonic nanosystems can unfold on timescales in the attosec- ond regime and the direct measurements of plasmonic near-field oscillations is highly desirable. We

Field-driven photoemission from nanostructures quenches the quiver motion

TLDR
The transition to a new regime in strong-field dynamics, in which the electrons escape the nanolocalized field within a fraction of an optical half-cycle is observed, characterized by a spatial adiabaticity parameter.
