UXSS 2019 at CFEL Hamburg

Michael is organizing UXSS 2019, taking place in Hamburg, June 16-21, 2019. The ultrafast x-ray summer seminar (UXSS) is an annual school aimed at PhD students and junior postdocs working on or interested in learning about x-ray methods at free-electron laser sources. Topics range from basics of x-ray sources via atomic and molecular physics and chemical dynamics to structural biology and inelastic light scattering in correlated materials. Registration will open in early 2019.


Paper published in Science Advances

Our paper on cavity materials – how to manipulate matter with pure vacuum fluctuations of light – was published in Science Advances. Here is the press release.

The vacuum fluctuations of light (yellow wave) are amplified in an optical cavity (upper and lower reflecting mirrors). Crystal lattice vibrations (red atoms) at a two-dimensional interface surf this strong light wave. The thus mixed light-vibrational waves couple particularly strongly to electrons in a two-dimensional atomically thin material (green and yellow atoms), changing its properties.
