The Max Planck Institute of Quantum Optics wins “Otto-Hahn-Triple”

17.06.2015

Elisabeth Bothschafter, Andreas Reiserer, and Michael Krüger are excelled with the Otto Hahn Medal by the Max Planck Society.

This year, the Max Planck Society has awarded the Otto Hahn Medal 2014 to three young scientists who have completed their doctoral thesis at the Max Planck Institute of Quantum Optics: Elisabeth Bothschafter, Andreas Reiserer, and Michael Krüger.

Since 1978 the Max Planck Society has presented this honour annually to around 30 junior scientists for ground-breaking scientific achievements connected to their doctoral thesis. The award is intended to encourage highly talented people to decide for a career in fundamental research. In addition, Andreas Reiserer is going to receive the Otto Hahn Award that each section of the MPG annually donates to one scientist only.

Dr. Elisabeth Bothschafter receives the Otto Hahn Medal for “Investigations of the non-linear interaction of light and matter in dielectric materials on the attosecond time-scale”.

Elisabeth Bothschafter studied physics at the University of Stuttgart and engineering at the Ecole Centrale Paris in the framework of a double diploma program which she completed in 2009. Her diploma thesis was carried out in the Attosecond Physics Division of Prof. Ferenc Krausz at the MPQ. In 2010 she became a member of the International Max Planck Research School of Advanced Photon Science (IMPRS-APS) and continued as a doctoral student in the same division.

From 2012 to 2014 Elisabeth Bothschafter was Vice-President of the Student Chapter Munich of the Optical Society of America (OSA). In May 2014 she completed her thesis “Femtosecond and Attosecond Electron Dynamics in Semiconductors and Dielectrics” under the supervision of Prof. Reinhard Kienberger and received her doctoral degree from the Technische Universität München.

Elisabeth Bothschafter investigated the interaction of femtosecond light-pulses with electrons bound in silicon-dioxide whereby she discovered entirely new processes: she was able to demonstrate that – even at very high fields – the material would almost instantaneously react to the oscillations of light waves, but return to its former state after the laser pulse had passed. This result is of high importance concerning possible technical applications, for example optical transistors. Now she has a postdoc position in the group of Dr. Urs Staub at the “Swiss Light Source” at the Paul-Scherrer-Institut (Villigen, Switzerland).

Dr. Andreas Reiserer is awarded the Otto Hahn Medal for the “Nondestructive detection of an optical photon and the realization of a quantum gate between an atom and a photon”.

Andreas Reiserer studied physics at the University of Würzburg where he received his “Master of Science” in 2009. During that time he had a stipend of the “Studienstiftung des Deutschen Volkes”. His doctoral thesis made him come to Garching (near Munich) where he became a member of the Quantum Dynamics Division of Prof. Gerhard Rempe at MPQ.

In his doctoral thesis “A controlled phase gate between a single atom and an optical photon” he was working on several groundbreaking experiments in the field of quantum information science. Here, a single atom trapped inside a high-finesse optical cavity detects a single optical photon without destroying it. Using the photon as a “flying” quantum bit and the atom as a “stationary” one Andreas Reiserer was able to realize a quantum logic gate between light and matter. These experiments are of fundamental importance for the implementation of a future quantum internet.

Having received his doctoral degree at the Technische Universität München in 2014, Andreas Reiserer became a postdoctoral researcher in the “Quantum Transport” group of Prof. Dr. Ronald Hanson, Kavli Institute of Nanoscience and Technical University of Delft (Netherlands). The young scientist will also receive the Otto Hahn Award which implies the opportunity to become leader of a research group at a Max Planck Institute after having stayed abroad.

Nominated by the Max Planck Institute for the Science of Light, Dr. Michael Krüger receives the Otto Hahn Medal for “Investigations of ultrafast electronic processes on nanostructures with phase-controlled laser pulses”.

Michael Krüger studied physics at the Ludwig-Maximilians-Universität München where he received his diploma in 2009. Both his diploma thesis and his doctoral thesis were carried out in the research group “Ultrafast Quantum Optics” of Dr. Peter Hommelhoff at the MPQ.

In his thesis “Attosecond physics in strong-field photoemission from metal nanotips”, Michael Krüger observed pivotal processes of attosecond and strong-field science in solids. In the optical field of an intense laser pulse an electron is first driven away from its parent atom, but eventually returns to it within an optical half cycle. At the point of recollision, the energy the electron had gained can be radiated away, or the electron can just scatter elastically. The occurring of the latter process at a metal nano-tip has been demonstrated for the first time by Michael Krüger. That way the young scientist proved that the electrical field of the laser pulses allows controlling electrons at a nanoscale solid state system. This opens the door to extremely fast light-controlled electronics.

Having received his doctoral degree from the Ludwig-Maximilians-Universität München in October 2013, Michael Krüger followed his advisor Peter Hommelhoff, who had accepted a professorship at the Universität Erlangen-Nürnberg in 2012. Since June 2014 he has been a postdoctoral researcher in the group of Prof. Nirit Dudovich at the Weizmann Institute of Science in Rehovot, Israel. Last year he has received the Koshland Prize for outstanding postdoctoral fellows.

Elisabeth Bothschafter, Andreas Reiserer, and Michael Krüger will be presented with the Otto Hahn Medal – which is endowed with prize money of 7500 Euro – on the occasion of the General Meeting of the Max Planck Society in Berlin on June 17th, 2015. Olivia Meyer-Streng

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
