Ultrafast relaxation dynamics of the antiferrodistortive phase in Ca doped SrTiO3
M. Porer, M. Fechner, E. Bothschafter +19
The ultrafast dynamics of the octahedral rotation in Ca:SrTiO3 is studied by time resolved x-ray diffraction after photo excitation over the band gap. By monitoring the diffraction…

Inhibition of the photoinduced structural phase transition in the excitonic insulator TaNiSe
Selene Mor, Marc Herzog, Johannes Noack +7
Femtosecond time-resolved mid-infrared reflectivity is used to investigate the electron and phonon dynamics occurring at the direct band gap of the excitonic insulator TaNiSe$_…
