Filling-dependent doublon dynamics in the one-dimensional Hubbard model
Roman Rausch, Michael Potthoff
The fate of a local two-hole doublon excitation in the one-dimensional Fermi-Hubbard model is systematically studied for strong Hubbard interaction U in the entire filling range us…
Inertia effects in the real-time dynamics of a quantum spin coupled to a Fermi sea
Mohammad Sayad, Roman Rausch, Michael Potthoff
Spin dynamics in the Kondo impurity model, initiated by suddenly switching the direction of a local magnetic field, is studied by means of the time-dependent density-matrix renorma…
One-step theory of two-photon photoemission
J. Braun, R. Rausch, M. Potthoff +1
A theoretical frame for two-photon photoemission is derived from the general theory of pump-probe photoemission, assuming that not only the probe but also the pump pulse is suffici…
Relaxation of a classical spin coupled to a strongly correlated electron system
Mohammad Sayad, Roman Rausch, Michael Potthoff
A classical spin which is antiferromagnetically coupled to a system of strongly correlated conduction electrons is shown to exhibit unconventional real-time dynamics which cannot b…
