Non-linear responses and three-particle correlators in correlated electron systems exemplified by the Anderson impurity model
Patrick Kappl, Friedrich Krien, Clemens Watzenböck +1
Three-particle correlators are relevant for, among others, Raman, Hall and non-linear responses. They are also required for the next order of approximations extending dynamical mea…
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…
Enhancement of impact ionization in Hubbard clusters by disorder and next-nearest-neighbor hopping
Anna Kauch, Paul Worm, Paul Prauhart +3
We perform time-resolved exact diagonalization of the Hubbard model with time dependent hoppings on small clusters of up to sites. Here, the time dependence originates from a…
