Long-term memory magnetic correlations in the Hubbard model: A dynamical mean-field theory analysis
Clemens Watzenböck, Martina Fellinger, Karsten Held +1
We investigate the onset of a not-decaying asymptotic behavior of temporal magnetic correlations in the Hubbard model in infinite dimensions. This long-term memory feature of dynam…
Photoexcitations in the Hubbard model -- generalized Loschmidt amplitude analysis of impact ionization in small clusters
Clemens Watzenböck, Markus Wallerberger, Laurenz Ruzicka +3
We study photoexcitations in small Hubbard clusters of up to 12 sites, some of which show an increase of the double occupation after the electric field pulse through impact ionizat…
Efficient Adaptive Computation of the Dynamics of Mott Transistors
Winfried Auzinger, Lukas Einramhof, Karsten Held +4
We investigate time-adaptive Magnus-type integrators for the numerical approximation of a Mott transistor. The rapidly attenuating electromagnetic field calls for adaptive choice o…
Efficient Magnus-type integrators for solar energy conversion in Hubbard models
Winfried Auzinger, Juliette Dubois, Karsten Held +7
Strongly interacting electrons in solids are generically described by Hubbardtype models, and the impact of solar light can be modeled by an additional time-dependence. This yields…
