<Abstract>
New developments in laser technology allow us to create attosecond light pulses, as well as very intense short light flashes with X-ray wavelength. Such light can push matter to extreme non-equilibrium with interesting consequences observable in the future by the same kind of light.
A similar development is taking place in ultracold matter. Thanks to laser cooling technology, besides Bose Einstein condensates, a less well known but equally novel form of atomic matter can be created: Ultracold plasmas.
They live on a time scale of microseconds which is more than 10 orders of magnitude slower than the time scale of strongly coupled electron plasmas created by attosecond laser pulses. Yet, as will be detailed in the talk, both extreme states of matter in the ultracold and the ultrafast behave similarly.
This is a beautiful example for the universality of physical concepts. The two novel realizations of strongly coupled plasmas in the laboratory will boost our understanding of non-equilibrium dynamics in the next years.
