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…

Vacuum space charge effect in laser-based solid-state photoemission spectroscopy
J. Graf, S. Hellmann, C. Jozwiak +6
We report a systematic measurement of the space charge effect observed in the few-ps laser pulse regime in laser-based solid-state photoemission spectroscopy experiments. The broad…
