A collective of electrons under the influence of light


Dr. Peter Dombi is now leader of a new MPQ partner group in Budapest

The Max Planck Institute of Quantum Optics has a new research partner group at the Wigner Research Centre for Physics, which is part of the Hungarian Academy of Sciences in Budapest. Dr. Dombi’s research group will work together closely with the Laboratory for Attosecond Physics (LAP) of Prof. Ferenc Krausz at the MPQ for the next three years.

Dombi’s team is working on ultrafast interactions of electron collectives in solid states with light, processes which take place within femtoseconds to attoseconds. A femtosecond is a millionth of a billionth of a second (10 to the minus 15), an attosecond is even a thousand times shorter.

In 2013, Prof. Krausz and his team were able to demonstrate for the first time that it is possible to control electrical and optical properties of solid states by using the electrical fields of light. Scientists were now able to turn electric current on and off by using light.

Furthermore light signals could be controlled with the frequency of visible light which oscillates a million times a billion (10 to the 15) per second. Dr. Dombi and his group in Hungary will continue the research on the basis of this knowledge. They will mainly concentrate on ultrafast nanoplasmonic phenomena.

In the field of nanoplasmonics physicists investigate the behaviour of collectives of electrons in solid states of nanometre size, for example metallic nanoparticles. When these collectives are excited by light they generate electric fields at the surfaces. Understanding these light-steered phenomena will help to pave the way towards “light-wave electronics” which operates at frequencies about 100,000 times faster than today’s techniques.

The Max Planck Society is presently related to more than 40 partner groups worldwide. These relations serve as basis for a collective support of young scientists in countries which are interested in research via international cooperation. These countries are, e.g., India, China, Middle and Eastern European as well as South American countries. After three years the work of a group will be evaluated and can be extended up to five years, if the evaluation comes to a positive result.

The Wigner Research Centre for Physics is the largest physics research institute in Hungary with more than 350 employees and 40 research groups. More than 50 years ago, the first laser has been constructed in Hungary and ever since optics and light-matter interactions have been very important elements of the research program. Now, due to this new cooperation with the MPG an important line of research will be added to this program. Thorsten Naeser

Im Focus: Kick-off for a new era of precision astronomy

The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.

As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...

Im Focus: Locusts at the wheel: University of Graz investigates collision detector inspired by insect eyes

Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.

Im Focus: High-speed march through a layer of graphene

In cooperation with the Center for Nano-Optics of Georgia State University in Atlanta (USA), scientists of the Laboratory for Attosecond Physics of the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität have made simulations of the processes that happen when a layer of carbon atoms is irradiated with strong laser light.

Electrons hit by strong laser pulses change their location on ultrashort timescales, i.e. within a couple of attoseconds (1 as = 10 to the minus 18 sec). In...
