Magnetism dominates our everyday lives, for example, sensors in traffic, computer hard drives, health technology and security systems. The universities of Lorraine, Kaiserslautern and Saarbrücken investigate magnetic applications within the Greater Region Magnetism Network (GRMN). The Spintronics Technology Platform STeP was presented by the research group magnetism of the University of Kaiserslautern along with the Johannes Gutenberg University Mainz. STeP is devoted to research and development of magnetic multilayer systems, applicable, for example, in sensors and memory units to be made available to companies. The Rhineland-Palatinate Minister of Economic Affairs Eveline Lemke and Assistant State Secretary Inga Schäfer of the Rhineland-Palatinate Ministry of Education, Science, Further Education and Culture visited the booth and gained information about the project. Industrial partner of this platform is Sensitec GmbH (Mainz); further networking between science and industry is realized by the Innovation Platform Magnetic Microsystems INNOMAG. In the center of the GRMN presentation was the VibroMag cable that allows fully automatic monitoring of fence systems of any size by magnetic sensors. "The process is relatively inexpensive, has a low false alarm rate and allows the precise localization of any intrusion," explains the physicist Professor Hartmann of the Saarland University, coordinator of the GRMN network. Several promising contacts within Germany and other European countries to further develop this product could be made in Hanover. A future sensor system for application in vehicles, developed by the GRMN partner from Nancy, was also presented at the fair. In this application, magnetic sensors measure rotations and angles of car tires.]]> standard research Optimas Mon, 15 Apr 2013 15:02:00 +0200 http://optimas.uni-kl.de/en/news/news/article/wissenschaft-und-for/ Communicating new results from research and development is typically a direct matter among experts...

"Dual Career" is an important aspect within OPTIMAS to attract new employees
Decorated with PhD degrees of the prestigious Chinese Academy of Sciences, postdocs Jingyi Mao (before Institute of Physics, Beijing) and Xuefeng Zhang (before Institute of Theoretical Physics, Beijing) recently decided for TU Kaiserslautern’s Physics Department for further pursuing their scientific careers. Xuefeng Zhang is now a postdoctoral scientist in the group of Professor Sebastian Eggert, working on the theory of correlated ultracold atoms. Being awarded with a personal grant of the Carl-Zeiss-Foundation, Jingyi Mao now pursues new methods for ultrafast magnetization dynamics of complex magnetic materials in the research group of Professor Martin Aeschlimann. “After having stayed before with my group as a PhD student for an intermediate research stay, I was very glad that Xuefeng Zhang decided to return to my research group as a postdoc.”, says Professor Sebastian Eggert. “His decision was strongly supported by the offer of my colleague, Martin Aeschlimann, to Xuefeng Zhang’s wife, Jingyi Mao, to later join his research group in experimental physics. Both are excellent young scientists, so that all parties greatly benefit from this effort to find a dual career-solution for the two of them.”, Professor Eggert adds. As their current advisors are both leading experts in their fields, Sebastian Eggert in the theory of many body systems, Martin Aeschlimann in ultrafast surface physics, Xuefeng Zhang and Jingyi Mao gladly accepted their job offers. However, their move from Beijing to the much quieter city of Kaiserslautern meant a huge change in life style to which they have well adapted. In their eyes there are only two backdraws in their decision, missing family and friends and, despite TU Kaiserslautern’s very good Mensa, missing the variety and quality of Chinese cuisine. Both of them have already been very successful in their research work in the framework of the OPTIMAS Research Center. Thus, Xuefeng Zhang managed recently to publish his study in the prestigious scientific journal Physical Review Letters: Xue-Feng Zhang, Qing Sun, Yu-Chuan Wen, Wu-Ming Liu, Sebastian Eggert, and An-Chun Ji, Rydberg Polaritons in a Cavity: A Superradiant Solid, Phys. Rev. Lett. 110, 090402 (2013). This collaborative effort of the Chinese Academy of Sciences, Beijing Capital Normal University and TU Kaiserslautern, yielded the first description of a “superradiant solid” as a novel phase in cavity quantum electrodynamics (QED) by using both analytic method and quantum Monte Carlo simulation. In this phase, photons couple to Rydberg atoms which results in a phase-coherent quantum “superradiant” state similar to a Bose-Einstein condensate.  The surprising feature is that the excitations simultaneously arrange in a periodical structure analogous to a solid.  Such a “superradiant solid” phase is quite unexpected, equally exotic as a Helium superfluid which would simultaneously be a solid.]]> standard research Optimas Mon, 18 Mar 2013 11:34:00 +0100 http://optimas.uni-kl.de/en/news/news/article/intensive-week/ April 8 - 12, 2013, Technische Universität Kaiserslautern, AG Widera labs and seminar room

Following four successful meetings in Europe, FINESS-2013 (Finite-Temperature Non-Equilibrium Superfluid Systems, 16-20 February 2013) brings together international physicists in Queenstown, New Zealand.
The aim of this conference is to discuss the nonequilibrium dynamics and thermodynamics of superfluids and strongly interacting gases at finite temperature and out of thermal equilibrium. In recent years, finite temperature and out of equilibrium dynamics have become accessible in ultracold quantum gases through new preparation and detection methods. A special objective of the conference is the comparison of and exchange about theoretical and experimental methods for studying the physical phenomena. The topics of the conference offer new exciting insights into the dynamics of many-body quantum systems, and promise new connections to systems in solid-state and high-energy physics.
As non-equilibrium phenomena are a central topic of OPTIMAS research, five scientists are taking part in the conference despite the long journey. Michael Fleischhauer, designated speaker of a new OPTIMAS research program that is currently in preparation, will give a lecture on “Many-body dynamics in open systems: Rydberg gases and Rydberg polaritons.” The conference will also be attended by Bill Phillips, Nobel Prize winner in 1997. ]]> standard research Optimas Mon, 11 Feb 2013 07:00:00 +0100 http://optimas.uni-kl.de/en/news/news/article/mainz-und-kaiserslau/ Two new joint large-scale research projects in materials science and spintronics at the... Two new joint large-scale research projects in materials science and spintronics at the universities of Mainz and Kaiserslautern with application potential Two large-scale research projects in materials science and spintronics have been initiated at Johannes Gutenberg University Mainz (JGU) and the University of Kaiserslautern. Both projects have a financial volume of more than EUR 3.8 million and are receiving support through the "Wachstum durch Innovation" (Growth through Innovation) program to the tune of some EUR 2.37 million from the European Regional Development Fund (ERDF) and the state agencies for science and commerce. Their objective is to promote the rapid transition from university research to industrial application. It often takes years for theoretical ideas and products developed at universities to find their way into commercial production. The two new projects, STeP and TT-DINEMA, are designed to help speed up the process of conversion to marketable procedures and products. "The two projects will not only enable us to ensure that our universities remain at the cutting edge in the fields of materials science and spintronics in future, but will also make a very important contribution to helping companies in Rhineland-Palatinate gain quick and easy access to innovation-relevant expertise in these high-tech areas," claimed Minister of Science Doris Ahnen. "The STeP project represents an important element in the development of a process of efficient preliminary research within the innovation network Magnetic Microsystems InnoMag e.V.," Minister of Economic Affairs Eveline Lemke went on to emphasize. The aim of the Mainz-based network is to develop innovative magnetic microsystems for new applications with significant commercial potential in areas such the automotive industry, automation, bioanalytics, and security technology. In the automation sector, for example, such products are invaluable because of their high resolution, reliability, and robustness when used in equipment such as assembly and machine tools and industrial robots. The purpose of the Spintronic Technology Platform in Rhineland-Palatinate (STeP) is to promote the sustained build-up of technical competencies and to support regional companies working in the spintronics sector. The platform has been specifically designed to bolster research into and the development of magnetic coating systems, which are particularly suitable for use in products such as sensors and memory storage units. At the core of the research being undertaken by STeP are so-called Heusler materials. The objective is to develop "building block systems" using innovative coating systems, which can then be flexibly adapted to meet the wide range of different functional and technological challenges. In a new approach, the results of academic research are being immediately transferred onto an industrial production line that meets DIN standards. This is an important requirement if experimental data is to be subsequently directly transformed into conventional production processes in the semi-conductor industry. The researchers have been able to win over as a partner the company Sensitec GmbH (Mainz), which has recently gained attention as a supplier of state-of-the-art sensors for the Mars Rover Curiosity. The aim of the TT-DINEMA ("Technologietransfer-Dienstleistungszentrum für Neue Materialien" or Technology Transfer Service Center for New Materials) project is to establish an internationally competitive and independent service center that can provide original new material concepts. It represents the starting point for innovative development projects in various fields of applications, ranging from solar technology through medical technology to thermoelectrics, and is likely to be of particular benefit to small and medium-sized companies. Again, Heusler compounds are at the focus of attention concerning the applied materials. These relatively simple chemical compounds represent an ideal combination in that they have a large diversity of different physical characteristics but can be relatively easily manufactured. This makes them suitable for use in various products, such as solar cells, semi-conductors, and thermoelectric systems for power generation from waste heat. In addition to their broad application potential, these materials are also interesting from the commercial point of view because of their low cost, sustainability, environmental friendliness, and ease of processing. The current primary intention of the TT-DINEMA project is to acquire two highly complex, state-of-the-art pieces of equipment: an industrial coating machine called sputtering deposition plant and a system for the production of starting materials. The complicated infrastructure and process technology needed for the provision of services in the research and development sector will be provided by the universities of Mainz and Kaiserslautern. The Graduate School of Excellence "Materials Science IN MainZ" (MAINZ) and the state research center OPTIMAS are also involved in both projects.

The understanding and control of quantum many-body systems far from equilibrium is an important research field in many areas of physics. Ultra-cold quantum gases, trapped ions as well as optical micro-resonators are ideal model systems to study these questions. The international workshop on “Quantum Many-Body Dynamics in Open Systems” will concentrate, in particular, on non-equilibrium dynamics of many-body systems which are coupled to external reservoirs or driven by external forces. Topics of the workshop will include

• Non-equilibrium dynamics in closed and open quantum many-body systems
• Relaxation and thermalization in many-body systems
• Dynamics in engineered environments and reservoir induced phenomena

With this year's price two pioneers of quantum engineering are honored whose experimental achievements have brought us closer to an understanding of the fundamentals of quantum physics and at the same paved the way for a controlled manipulation of individual quantum systems such as ions or photons.

David Wineland, from the National Bureau of Standards in Boulder, studied physics at Berkeley, made his PhD with Norman Ramsey at Harvard and was a post-doc with Hans Dehmelt where he worked on the trapping and control of individual electrons in a Penning trap. Since then he developed the techniques of trapping and state preparation of ions into an art which allows control of individual quantum systems with unprecedented precision. This has lead to important applications in metrology, in particular frequency standards. It is also not surprising that the first proposals for a quantum computer were formulated for ion trap systems. Since then quantum information processing with ions has made tremendous progress thanks to the pioneering work of David Wineland.

Serge Haroche studied physics at the Ecole Normale in Paris and made his PhD with Claude Cohen-Tannoudji on the interaction of light with atoms. The quantum nature of elecromagnetic radiation was since early on a central theme of his research. He pioneered the field of cavity QED which allowed to realize a strong radiative coupling between an individual atom and a single mode of the radiation field. This lead to a number of fascinating experiments. An example is the observation of the periodic energy exchange between atom and field initially prepared in the vacuum state, which provided a direct proof of the granular structure of photons. Other experiments include the preparation and detection of Schroedinger cat states, or the nondestructive measurement of the photon number in a resonator. State manipulation of individual quantum systems is also a central theme of research in OPTIMAS, where, e.g., individual atoms embedded in a BEC or the coherent manipulation of individual spins in systems of varying size are studied.]]> Optimas research standard Wed, 12 Dec 2012 15:16:00 +0100 http://optimas.uni-kl.de/en/news/news/article/atom-probe-tomograph/ 20 and 27 November 2012 (in the mornings), IFOS at TU Kaiserslautern Course description
Atom probe tomography (APT) produces 3-D compositional images at the atomic
scale with very high analytical sensitivity (10 atomic parts per million). It does so by controllably extracting atom (ions) from a specimen with a very high electric field applied to the surface. The extracted ions are projected onto a position-sensitive detector for recording their location. Time-of-flight measurements on the ions provide their isotopic identity as a mass-to-charge ratio of the ion. Because the fundamental data format is the 3-D position (with a spatial resolution of 0.2 nm) and identity of atoms (isotopes, actually) in a volume containing potentially hundreds of millions of atoms, many types of analytical information may be gleaned.
