Bypassing the structural bottleneck in the ultrafast melting of electronic order
L. X. Yang, G. Rohde, K. Hanff. A. Stange +4
The emergent properties of quantum materials, such as symmetry-broken phases and associated spectral gaps, can be effectively manipulated by ultrashort photon pulses. Impulsive opt…
Collapse of layer dimerization in the photo-induced hidden state of 1T-TaS2
Quirin Stahl, Maximilian Kusch, Florian Heinsch +6
Photo-induced switching between collective quantum states of matter is a fascinating rising field with exciting opportunities for novel technologies. Presently very intensively stu…
Extreme timescale core-level spectroscopy with tailored XUV pulses
R. Singla, D. C. Haynes, K. Hanff +8
A new approach for few-femtosecond time-resolved photoelectron spectroscopy in condensed matter that balances the combined needs for both temporal and energy resolution is demonstr…
Decoding the ultrafast formation of a Fermi-Dirac distributed electron gas
Gerald Rohde, Ankatrin Stange, Arne Müller +7
Time- and angle-resolved photoelectron spectroscopy with 13 fs temporal resolution is used to follow the different stages in the formation of a Fermi-Dirac distributed electron gas…
