Ultrafast switching of composite order in AC
Philipp Werner, Hugo Strand, Shintaro Hoshino +1
We study the controlled manipulation of the Jahn-Teller metal state of fulleride compounds using nonequilibrium dynamical mean field theory. This anomalous metallic state is a spon…
Nonequilibrium Dynamical Cluster Approximation study of the Falicov-Kimball Model
Andreas J. Herrmann, Naoto Tsuji, Martin Eckstein +1
We use a nonequilibrium implementation of the dynamical cluster approximation (DCA) to study the effect of short-range correlations on the dynamics of the two-dimensional Falicov-K…
Ultrafast Electronic Band Gap Control in an Excitonic Insulator
Selene Mor, Marc Herzog, Denis Golež +8
We report on the nonequilibrium dynamics of the electronic structure of the layered semiconductor TaNiSe investigated by time- and angle-resolved photoelectron spectroscopy…
Interference stabilization of autoionizing states in molecular studied by time- and angular-resolved photoelectron spectroscopy
Martin Eckstein, Nicola Mayer, Chung-Hsin Yang +4
An autoionizing resonance in molecular N is excited by an ultrashort XUV pulse and probed by a subsequent weak IR pulse, which ionizes the contributing Rydberg states. Time- an…
Photo-induced gap closure in an excitonic insulator
Denis Golež, Philipp Werner, Martin Eckstein
We study the dynamical phase transition out of an excitonic insulator phase after photo-excitation using a time-dependent extension of the selfconsistent GW method. We connect the…
Alignment and characterization of the two-stage time delay compensating XUV monochromator
Martin Eckstein, Johan Hummert, Markus Kubin +5
We present the design, implementation and alignment procedure for a two-stage time delay compensating monochromator. The setup spectrally filters the radiation of a high-order harm…
