Physicists from the Max Planck Institute of Quantum Optics trace the double ionization of argon atoms on attosecond time scales
05-11-2012
When an intense laser pulse interacts with an atom it generates agitation on the micro scale. A rather likely outcome of this interaction is single ionization, where one electron is ejected from the atom. From time to time, however, two electrons can be removed from the atom, resulting in the ...
Physicists at MPQ succeed in resolving the internal dynamics of individual molecules using UV femtosecond laser pulses
02-14-2012
Nowadays, large laser systems provide ultra-short light pulses of very high intensity which – in principle – allow the imaging of matter and its dynamics on atomic scales, down to a single molecule or a virus. However, current methods fall short in efficiency to overlap a target molecule in a ...
White laser pulses with precisely tailored waveform enable the control of electrons in the microcosm
09-12-2011
An expedition through the fast-paced microscopic world of atoms reveals electrons that spin around at enormous speeds and have gigantic forces are acting on them. Monitoring the ultrafast motion of these electrons requires ultrashort flashes of light. However, in order to control them, the ...

Physicists of the Laboratory of Attosecond Physics at the Max Planck Institute of Quantum Optics succeeded in the first real-time observation of laser produced electron plasma waves and electron bunches accelerated by them. Flocking behavior does not only exist among birds, insects or ...

For the first time ever, physicists from the Laboratory for Attosecond Physics (LAP) at the Max Planck Institute of Quantum Optics have observed what occurs inside an atom from which a single electron has been ejected. An international team from the Laboratory for Attosecond Physics, led by ...
MPQ-scientists demonstrate that due to synchronisation atoms can be influenced by forces as weak as 5 yoctonewton
08-06-2010
Back in the 17th century the Dutch physicist Christiaan Huygens made the observation that the oscillation of two pendulums synchronize once they get under mutual influence. This holds for even very loose coupling, for instance, when both pendulums are mounted onto the same wall. ...
International team of researchers observes unexpectedly small proton radius in a precision laser experiment with exotic hydrogen atoms
07-12-2010
The proton - one of the universal building-blocks of all matter - is even smaller than had previously been assumed. This is the result obtained at the Paul-Scherrer-Institut (PSI) in Villigen (Switzerland) by an international research team, including scientists from the Max Planck Institute ...
07-02-2010
When physicists search for new semiconductors for chips or lasers, they have been able to rely on sophisticated computer programs - until now. However, it is possible that the models these programs have used to predict the electronic properties of a material oversimplify reality. An ...
Physicists produce a Bose-Einstein condensate at zero gravity - a step towards extremely sensitive quantum sensors for gravitation
06-24-2010
A sensitive measuring device must not be dropped - because this usually destroys the precision of the instrument. A team of researchers including scientists from the Max Planck Institute of Quantum Optics has done exactly this, however. And the researchers want to use this experience to make ...

Dr. Eleftherios Goulielmakis, a young research scientist at the Max Planck Institute of Quantum Optics (MPQ) in Garching (Germany), has been chosen by the International Commission of Optics (ICO) and the Commission of the International Union of Pure and Applied Physics (IUPAP) that grants the ...
