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 team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
