Attosecond spectroscopy promises real-time observation of the motion of electrons inside atoms. Nadya Anscombe talks to Ferenc Krausz from the Max-Planck Institute of Quantum Optics and the Ludwig The speed of light (in free space) is defined as one ℓ P /one t P, i.e., the Planck time is the time light needs to travel one Planck length through free space. The answer (finally): One attosecond ≅ 1.86 ×10 25 t P, which is (“roughly”) the same number of Planck lengths that light travels in one attosecond! An international team from the Laboratory for Attosecond Physics (www.attoworld.de), led by Prof.

To perform conversions between Planck time and other Time units please try our Time Unit Converter Convert Planck time to: Real time observation of electron dynamics in matter. We develop advanced attosecond technologies to investigate the light-activated dynamics of matter with Instant free online tool for Planck time to attosecond conversion or vice versa. The Planck time to attosecond [as] conversion table and conversion steps are also our research.

We seek to adapt attosecond sources to study condensed-matter dynamics with sub-eV resolution, unfolding on the corresponding femtosecond timescale.

An attosecond is equal to 1000 zeptoseconds, or 1 ⁄ 1000 of a femtosecond. Because the next higher SI unit for time is the femtosecond (10 −15 seconds), durations of 10 −17 s and 10 −16 s will typically be expressed as tens or hundreds of attoseconds: Times which can be expressed in attoseconds:

See the special section on attosecond spectroscopy beginning on page 765. Einstein earned his Nobel Prize for a quantum-mechanical explanation of electron ejection from metals by light. More than a century later, attosecond spectroscopy has let researchers explore that process in real time. Tao et al. used attosecond pulse trains to distinguish the dynamics of electrons excited from a nickel surface into discrete states versus free space (see the Perspective by Photoionization time delays; 16.00 - 16.40: Reinhard Dörner.
