4 Stanford PULSE Institute, SLAC National Accelerator Laboratory, Menlo Park, CA, 94025, USA. Just as femtosecond pulses allow the observation of the motion of atoms in molecules, attosecond pulses will allow us to trace electronic motion and electronic relaxation (such as inner-shell Attosecond science. The motion of electrons on the atomic scale has been hidden from direct experimental access until recently. We review the revolution in technology that opened the door to real-time observation and time-domain control of atomic-scale electron dynamics, and address the expected implications of having the tools to monitor electrons with sub-atomic resolution in both space and time. 1.

In molecular photoionization, these barriers prevent the electron from escaping instantaneously, so that nuclei may move and modify the potential, thereby affecting the ionization process.

Attosecond The attosecond science group at the Stanford PULSE Institute focuses on dynamics on this timescale, which is a science frontier both for experiments and for quantum many-body theory. Ultrafast optical techniques are routinely used to interrogate chemical reactions on the timescale intrinsic to chemical change (i.e. the time scale for nuclear dynamics).

The central interest of our research is the characterization of the electronic structure … Attosecond science: the mission One of the great challenges for attosecond scientists is to step up photon energy from the current range of 30 to 130 eV to several hundred electron volts and – in the longer term – to the kilo-electronvolt range.

In this paper the fastest electronic relaxation dynamics ever measured has been observed by attosecond transient-absorption spectroscopy (ATAS) at the carbon K-edge. Attosecond science works somewhat like sonar or 3D laser mapping, but at a much smaller scale.

We review the revolution in technology that opened the door to real-time We review the first ten years of attosecond science with a selection of recent highlights and trends and give an outlook on future directions. After introducing the main spectroscopic tools, we give recent examples of representative experiments employing them. Some of the most fundamental processes in nature have been studied with some results initiating controversial discussions.

When the electron wavepacket is formed by tunnel ionization in linearly polarized light, attosecond electron or optical pulses can be produced, both of which will play significant rolls in attosecond spectroscopy. On the other hand, those nonlinear processes in the XUV region is indispensable for progress of attosecond science including attosecond atomic/molecular physics and chemistry, because it is very useful for investigating ultrafast phenomena directly in attosecond time scale. How to get the very short pulses needed for attosecond science wasn’t completely clear, he says, “but it seemed like it should only be a technical challenge.” Compressing light For light compression, Chini says, researchers commonly use self-phase modulation in noble-gas-filled hollow-core capillary fibers to generate a broad spectrum, and then compress the pulses using chirped mirrors. Attosecond science has been transforming our understanding of electron dynamics in atoms, molecules, and solids.
