Abstract given by the source: Within the project several aspects of nonlinear and collective effects in quantum plasmas will be studied. An important part will be the further development of selfconsistent models of quantum plasmas. The models developed so far have shown that the electron spin properties can induce quantum behavior in regimes previously believed to be purely classical. Preliminary investigations indicate that these results can be sharpened even more if the hydrodynamical quantum models are generalized into kinetic models, using an eight-dimensional phase space (i.e. position, momentum and two spin degrees of freedom). This will provide the basis for a thorough analysis of the transmission between classical and quantum behavior in plasmas. An improved understanding of quantum plasmas is also a key factor when addressing problems in the recently developed field of plasmonics. Here surface plasmon polaritons (SPPs) are used for signal transmission in components aimed to be the next generation of computer chips. Within the project it is an important goal to give an improved theoretical description of SPPs, involving a full quantum treatment, which will be crucial when the sizes of the components shrink beyond 100 nm. Finally, the project aims to address problems in high-power laser plasma interaction, including both plasma collective effects as well as quantum electrodynamical effects. The development of high power laser proposals such as ELI and HiPER make such treatments necessary.
