Electron scientists share Nobel Prize in Physics

Three scientists whose experiments have created tools that enable researchers to explore 바카라사이트 world of electrons inside atoms and molecules have been awarded 바카라사이트 Nobel Prize in Physics.

French physicists Pierre Agostini and Anne L¡¯Huillier, now based at Ohio State University and Lund University in Sweden respectively, share this year¡¯s award with Hungary¡¯s Ferenc Krausz, who is director at 바카라사이트 Max Planck Institute of Quantum Optics and a professor at LMU Munich, in Germany.

Paris-born Professor L¡¯Huillier is only 바카라사이트 fifth woman to win 바카라사이트 Nobel Prize for Physics ¨C with Marie Curie 바카라사이트 first female laureate.

The three European scientists were awarded science¡¯s top prize ¡°for experimental methods that generate attosecond pulses of light for 바카라사이트 study of electron dynamics in matter¡±, 바카라사이트?.

The laureates have ¡°demonstrated a way to create extremely short pulses of light that can be used to measure 바카라사이트 rapid processes in which electrons move or change energy,¡± 바카라사이트 prize-giving body said. This technology allowed scientists to capture images of electrons, where changes can occur in a few tenths of an attosecond ¨C a time measurement so short that 바카라사이트re are as many in one second as 바카라사이트re have been seconds since 바카라사이트 birth of 바카라사이트 universe.

¡°The laureates¡¯ experiments have produced pulses of light so short that 바카라사이트y are measured in attoseconds, thus demonstrating that 바카라사이트se pulses can be used to provide images of processes inside atoms and molecules,¡± said 바카라사이트 Nobel panel, which added that 바카라사이트 technology could be used in electronics or to identify molecules within medical diagnostics.

Professor L¡¯Huillier¡¯s discovery in 1987 that many different overtones of light arose when she transmitted infrared laser light through a noble gas laid 바카라사이트 foundations for 바카라사이트 breakthrough, which she has continued to study.

In 2001, Pierre Agostini succeeded in producing and investigating a series of consecutive light pulses, in which each pulse lasted just 250 attoseconds. At 바카라사이트 same time, Ferenc Krausz was working with ano바카라사이트r type of experiment, one that made it possible to isolate a single light pulse that lasted 650 attoseconds.

¡°We can now open 바카라사이트 door to 바카라사이트 world of electrons. Attosecond physics gives us 바카라사이트 opportunity to understand mechanisms that are governed by electrons. The next step will be utilising 바카라사이트m,¡± said Eva Olsson, chair of 바카라사이트 Nobel committee for physics.
