Hanbury Brown and Twiss interferometry at a free-electron laser
A. Singer, U. Lorenz, F. Sorgenfrei +11
We present measurements of second- and higher-order intensity correlation functions (so-called Hanbury Brown and Twiss experiment) performed at the free-electron laser (FEL) FLASH…

Spatial and temporal coherence properties of single free-electron laser pulses
A. Singer, F. Sorgenfrei, A. P. Mancuso +16
The experimental characterization of the spatial and temporal coherence properties of the free-electron laser in Hamburg (FLASH) at a wavelength of 8.0 nm is presented. Double pinh…

Ultrafast melting of a charge-density wave in the Mott insulator 1T-TaS2
S. Hellmann, M. Beye, C. Sohrt +11
Femtosecond time-resolved core-level photoemission spectroscopy with a free-electron laser is used to measure the atomic-site specific charge-order dynamics in the charge-density-w…
