Congratulations to the doctorate

In July 2023, the Faculty of Mathematics and Natural Sciences at the University of Rostock awarded Benjamin Liewehr (M.Sc.) the degree of Dr. rer. nat.

His dissertation project on ultrafast nanoplasma dynamics in dielectrics was carried out in the strong-field nanophysics group of Prof. Thomas Fennel and is closely linked to research in the field of strong-field physics and attosecond research within the CRC 1477 - Light-Matter Interaction at Interfaces. Immediately after completing his dissertation, he found an exciting job in industry and is currently working at Liebherr MCCtec Rostock GmbH.

The SFB LiMatI congratulates!

Announcement: Lecture on the Nobel prize on 09.11.2023

Taming light waves ... and other stories

The Nobel Prize in Physics this year was awarded for the generation of ultra-short light pulses. These pulses are so brief (namely 0.000000000000000001 seconds = 1 attosecond) that they can be used to „photograph“ the motion of electrons in matter. This field of research, known as attosecond physics, is a crucial area of study at the Institute of Physics and the Collaborative Research Center LiMatI. Professor Eleftherios Goulielmakis worked in the research group of the newly crowned Nobel laureate Ferenc Krausz before his appointment to Rostock and conducted groundbreaking experiments in the field of attosecond physics.

In the Physics Colloquium Professor Goulielmakis will speak on the topic „Taming light waves: The physics of the Nobel prize 2023 and other stories...“ (in English). Interested individuals are cordially invited!

Wann: on November 9, 2023, at 4:15 PM ,

Wo: Lecture Hall 1, Institute of Physics, Albert-Einstein-Straße 24


Poster presentation award

Our PhD student Julian Schröer received a poster presentation award from the Royal Society of Chemistry at Flatlands beyond Graphene 2023 in late September. The award was supported by the journals Nanoscale Horizons, Nanoscale and Nanoscale Advances.

Julian Schröer works in the LiMatI subproject W04 and investigates the physics at interfaces between organic dye molecules and inorganic semiconductors. At the conference, he presented his results on photoluminescence spectroscopy of heterostructures from both materials. Among other things, his investigations focus on a potential charge transfer between the materials, which forms the basis for applications in photovoltaics.

The SFB LiMatI congratulates!

Nobel prize physics 2023

The three researchers Pierre Agostini, Ferenc Krausz and Anne L'Huillier are awarded for developing the experimental methods to generate extremely short light pulses to study electron dynamics in matter. These attosecond pulses make it possible to explore the superfast motion processes and energy changes of electrons in atoms and molecules.

Fast-moving events flow into each other when perceived by humans, just like a film that consists of still images is perceived as continual movement. If we want to investigate really brief events, we need special technology. In the world of electrons, changes occur in a few tenths of an attosecond – an attosecond is so short that there are as many in one second as there have been seconds since the birth of the universe. The laureates’ experiments have produced pulses of light so short that they are measured in attoseconds, thus demonstrating that these pulses can be used to provide images of processes inside atoms and molecules.

In 1987, Anne L’Huillier discovered that many different overtones of light arose when she transmitted infrared laser light through a noble gas. Each overtone is a light wave with a given number of cycles for each cycle in the laser light. They are caused by the laser light interacting with atoms in the gas; it gives some electrons extra energy that is then emitted as light. Anne L’Huillier has continued to explore this phenomenon, laying the ground for subsequent breakthroughs.

In 2001, Pierre Agostini succeeded in producing and investigating a series of consecutive light pulses, in which each pulse lasted just 250 attoseconds.

At the same time, Ferenc Krausz was working with another type of experiment, one that made it possible to isolate a single light pulse that lasted 650 attoseconds.

Our LiMatI physicist Eleftherios Goulielmakis contributed to the results at that time while working on his PhD thesis under Ferenc Krausz.

Talk: Dr. Nina Meinzer

On Friday, June 23, 2023 at 2 pm, Dr. Nina Meinzer (Senior Editor & Team Leader Nature Physics) gave a talk on the topic:

How to talk to a non-specialist

The talk was part of the joint SFB 1270 ELAINE and SFB 1477 LiMaI lecture series "Women in Science and (Bio-)Engineering"

We thank all visitors for their participation!

Controlled tunneling

How short can the time window be in which electrons can be released from metals under the control of a light field? Researchers of LiMatI project S05 were able to answer this question, which is essential for future electronic circuits, in a collaborative experimental and theoretical study together with scientists from Erlangen and Konstanz with the help of a trick. By means of an extremely precisely adjustable superposition of two different laser fields, we have succeeded for the first time in measuring the tunneling of electrons from metals down to a few tens of attoseconds and in controlling the ultrafast electronic quantum dynamics. The findings could enable electronic signal processing that is up to a million times faster than current technology and were recently published (Dienstbier et al., Nature 616, 702-706 (2023)).

Electrons in the fast lane

Within LiMatI project S05 a study on the generation and measurement of the shortest electron pulse to date was published in Nature (Kim et al., Nature 613, 662-666 (2023)). The pulse was generated using lasers to release electrons from a tiny metal tip and lasted only 53 attoseconds, that is 53 billionths of a billionth of a second. The study sets a new speed record in man-made control of electric currents in solid materials and opens new possibilities for improving the performance of electronics and information technologies, as well as for developing new scientific methods for visualizing phenomena in the microcosm at ultimate speeds.
