Max Planck Institute for the Structure and Dynamics of Matter

New methods are enabling physicists and biologists at the Max Planck Institute for the Structure and Dynamics of Matter to break new scientific ground. With the help of new radiation sources, especially the x-ray free-electron laser being built at the DESY in Hamburg, the researchers can show the properties and behavior of matter at a spatial resolution of a few nanometers and at time intervals of a few billionths of a billionth of a second. This provides them with completely new insights into the structure and function of biological materials and into the properties of solids and their electronic and structural dynamics. The coherent light of lasers enables the physicists to inspect the collective properties, for example superconductivity, of complex solids, including many types of ceramics.

To alter properties of materials with light as if with the wave of a magic wand: that is Andrea Cavalleri’s mission. The Director at the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg uses lasers to change the behavior of crystals, fleetingly producing superconductors that conduct electricity without loss at room temperature.

Light-induced superconductivity: footballs carry an electrical current without resistance

2018 Först, Michael; Nicoletti, Daniele; Cavalleri, Andrea

Material Sciences Solid State Research

Superconductors at very low temperatures show the remarkable property of being able to conduct electrical current without any resistance. However, the use of these materials in everyday life applications is severely limited by the need for cooling to at least minus 70 degrees Celsius. In carbon-based molecules, irradiation with intense mid-infrared laser light has now enabled to induce a short-lived transient superconducting state at higher temperatures. The knowledge gained might help in the development of materials that become superconducting at significantly higher temperatures.

How light changes matter: from a laser to a few photons

2017 Ruggenthaler, Michael; Hübener, Hannes; Sentef, Michael A.; Appel, Heiko; Rubio, Angel

Chemistry Material Sciences Quantum Physics Solid State Research

The properties of matter, e.g., the conductivity, can be tailored with light. This can be done with a lot of photons that are part of a laser beam, or in certain cases only a few photons are enough. In the theory department of the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, researchers use both extreme cases to investigate novel states of matter: a laser allows theoretically generating hitherto unobserved states of matter and via a few photons chemical reactions can be altered.

Molecular movie from Hamburg

2016 Hayes, Stuart; Manz, Stephanie; Bücker, Robert; Kassier, Günther; Miller, R.J. Dwayne.

Chemistry Material Sciences

Many processes in the chemistry of life take place on ultrashort length and time scales. Their observation thus lies beyond the capabilities of optical microscopes. The investigation of such processes using novel electron sources in many cases presents a cost-saving alternative to X-ray studies using synchrotron radiation sources and free-electron lasers. Also the development of methods for the preparation of liquid samples is essential for the study of many organic materials.

Superconductivity at room temperature: A dream becomes reality for a split second

2015 Först, M.; Mankowsky, R.; Kaiser, S.; Hu, W.; Cavalleri, A.

Material Sciences Solid State Research

Superconductors carry an electric current without resistance only at low temperatures. Now, for the first time, scientists have turned a ceramic crystal into a superconductor even at room temperature, using an ultrashort mid-infrared flash of light. The superconducting state survived only for a couple of picoseconds (millionth of a microsecond), and the researchers found that this light-induced state is based on certain distortions of the material’s crystal lattice. These findings may aid the quest for higher temperature superconductors and pave the way for novel applications.
