Matthias Bartelmann - A microscopic theory for cosmic structures

Hamburg Photon Science Colloquium
Our Universe is permeated by a network of filamentary structures showing a remarkable degree of universality. When treated as a huge ensemble of correlated classical particles out of equilibrium, the properties and the evolution of these structures can be modelled and understood in a straightforward way. I shall describe a new theory for cosmic structures and first results obtained from it. [more]

Justin Wark - Creating & Diagnosing Solid Density Plasmas with an X-ray FEL

Hamburg Photon Science Colloquium
4th generation light sources provide the capability to irradiate solids with X-rays at intensities in the range of optical lasers. At high focused intensities and sub-100 fs pulse lengths, solid targets transform to plasmas at several millions of degrees Kelvin. Detailed X-Ray spectroscopy allows us to probe the physics of these dense plasmas, and initial results have challenged our understanding of such basic details as how many bound states exist, and the rate at which collisions occur. It appears that current understanding of dense plasmas is woefully inadequate. [more]
