A strong oscillating laser field can create modulations in the electron wavefunction. The wavepacket can expand over ~10-100 hydrogen-atom sizes away from the parent ion. Joint Attosecond Science Laboratory. The Joint Attosecond Science Laboratory is a partnership between the National Research Council of Canada and the University of Ottawa.

Attosecond science

Pushing the frontiers in attosecond quantum mechanics with increasing temporal and spatial resolution and often-limited theoretical models results in unexpected observations. At the same time, attosecond science continues to expand into more complex solid-state and molecular systems, where it starts to have impact beyond its traditional grounds. Anyone interested in Attosecond science is welcome to join! The Lund Attoscience Symposium 2021 will offer monthly two-hour sessions on Wednesdays from 16.00 to 18.00. Each session focuses on one aspect of attosecond science and consists of one keynote lecture in addition to three progress reports from early career researchers.

In particular, the main goal of our research is to track and ideally control the electronic motion in systems of increasing complexity, from simple molecules to biochemically relevant molecules and nanoparticles. Attosecond science based on high harmonic generation from gases and solids Recent progress in high power ultrafast short-wave and mid-wave infrared lasers has enabled gas-phase high harmonic generation (HHG) in the water window and beyond, as well as the demonstration of HHG in condensed matter.

Sedan den första demonstrationen av isolerade attosekund ( 10-18 s) pulser 2001 har fältet Attosecond science utvecklats snabbt, vilket förstärker vår förståelse

Dahlström, Marcus (författare): Lunds universitet (utgivare). Publicerad: 2016 We kindly invite you to the Lund Attoscience Symposium, a monthly two-hour virtual meeting on selected topics in the field of attosecond science with []. CERN Accelerating science A case study for terahertz-assisted single attosecond pulse generation - Balogh, Emeric et al - arXiv:1402.3120.

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.

March 9 at 4:29 AM ·. Digging into the literature for our Journal Club: an interesting paper by K. S. Zinchenko et al. In this paper the fastest electronic relaxation dynamics ever measured has been observed by attosecond transient-absorption spectroscopy (ATAS) … 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. 2010-04-16 2021-01-29 A laser light shines in a gas cell where UCF researchers generate attosecond pulses. Courtesy: UCF. Studies of ultrafast processes could become more widely accessible thanks to researchers at the University of Central Florida (UCF) in the US, who have shown that commercially available, industrial-grade lasers can generate attosecond pulses of light. Attosecond Science ª Real time observation of electron dynamics in matter We develop advanced attosecond technologies to investigate the light-activated dynamics of matter with extreme time resolution. 2021-04-07 · Attosecond science Abstract.

For context, an attosecond is to a second what a second is to about 31.71 billion years. The word "attosecond" is formed by the prefix atto and the unit second. Atto-was derived from the Danish word for eighteen (atten). Its symbol is as. Attosecond science offers formidable tools for the investigation of electronic processes at the heart of important physical processes in atomic, molecular and solid-state physics.

In particular, the main goal of our research is to track and ideally control the electronic motion in systems of increasing complexity, from simple molecules to biochemically relevant molecules and nanoparticles.

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.
