The senate of the Helmholtz-Gemeinschaft deutscher Forschungszentren (HGF) has, on Nov. 7 2007, approved the proposal of the Gesellschaft für Schwerionenforschung (GSI) Darmstadt for the Helmholtz Alliance "Extremes of Density and Temperature: Cosmic Matter in the Laboratory".
A central goal is the interdisciplinary investigation of matter under extreme conditions: from extremely hot matter of the big bang to ultra-cold quantum gases.
Contributing with several projects the MPI für Kernphysik Heidelberg is one of the core partners of the Alliance. In Joachim Ullrich's department world-leading "Electron Beam Ion Traps" and high-energy collisions at GSI are used to generate and to study matter under extreme conditions which are common, however, on star surfaces or even in supernova explosions. Selim Jochim, Juniorprofessor at the Institute, is working towards finite systems of ultracold fermions, an important goal within the Alliance.
The tunability of the interactions between these ultracold particles makes them an especially versatile model system. The department of Christoph Keitel supports the Alliance by calculations on the interaction of matter with extreme laser fields with emphasis on relativistic quantum dynamics, nuclear processes and quantum electrodynamic effects. The appointment of Klaus Blaum to the institute performing high-precision measurements of nuclear masses will place the MPIK among the top laboratories in the international scene exploring the question of heavy-elements genesis in stellar explosions, a further central research topic within the Alliance.
The Alliance connects GSI with the Max-Planck-Institut für Kernphysik and 6 other national partners (TU Darmstadt, Univ. Frankfurt, FIAS Frankfurt, Univ. Heidelberg, Forschungszentrum Jülich, Univ. Münster) as well as 4 international partners (Univ. Paris VI, France, Univ. Tokyo and RIKEN, Japan, Lawrence Berkeley National Laboratory and Joint Institute for Nuclear Astrophysics, USA). Leading international scientists, among them two Nobel laureates, will serve as associate partners. With this Alliance its partners will push forward the frontier of 'extreme matter' research. The HGF supports the Alliance with 18.75 Millions of Euros for a period of 5 years.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
