Photo-induced Dirac cone flattening in BaNiS
Nikolaj Bittner, Denis Golež, Michele Casula +1
Using a real-time implementation of the self-consistent method, we theoretically investigate the photo-induced changes in the electronic structure of the quasi two-dimensional…
Effects of frustration on the nonequilibrium dynamics of photo-excited lattice systems
Nikolaj Bittner, Denis Golež, Martin Eckstein +1
We theoretically investigate the effects of the lattice geometry on the nonequilibrium dynamics of photo-excited carriers in a half-filled two-dimensional Hubbard model. Using a no…
Photo-enhanced excitonic correlations in a Mott insulator with nonlocal interactions
Nikolaj Bittner, Denis Golez, Martin Eckstein +1
We investigate the effect of nonlocal interactions on the photo-doped Mott insulating state of the two-dimensional Hubbard model using a nonequilibrium generalization of the dynami…
Ultrafast coupled charge and spin dynamics in strongly correlated NiO
Konrad Gillmeister, Denis Golež, Cheng-Tien Chiang +5
Charge excitations across an electronic band gap play an important role in opto-electronics and light harvesting. In contrast to conventional semiconductors, studies of above-band-…
Coupled charge and spin dynamics in a photo-excited Mott insulator
Nikolaj Bittner, Denis Golež, Hugo U. R. Strand +2
Using a nonequilibrium implementation of the extended dynamical mean field theory (EDMFT) we simulate the relaxation after photo excitation in a strongly correlated electron system…
Correlation between Fermi surface transformations and superconductivity in the electron-doped high- superconductor NdCeCuO
T. Helm, M. V. Kartsovnik, C. Proust +11
Two critical points have been revealed in the normal-state phase diagram of the electron-doped cuprate superconductor NdCeCuO by exploring the Fermi surface propert…
