Real-Time Dynamics of Typical and Untypical States in Non-Integrable Systems
Jonas Richter, Fengping Jin, Hans De Raedt +3
For a class of typical states, the real-time and real-space dynamics of non-equilibrium density profiles has been recently studied for integrable models, i.e. the spin-1/2 XXZ chai…
Charge diffusion in the one-dimensional Hubbard model
R. Steinigeweg, F. Jin, H. De Raedt +2
We study the real-time and real-space dynamics of charge in the one-dimensional Hubbard model in the limit of high temperatures. To this end, we prepare pure initial states with sh…
Real-time broadening of non-equilibrium density profiles and the role of the specific initial-state realization
R. Steinigeweg, F. Jin, D. Schmidtke +3
The real-time broadening of density profiles starting from non-equilibrium states is at the center of transport in condensed-matter systems and dynamics in ultracold atomic gases.…
Finite-temperature charge transport in the one-dimensional Hubbard model
F. Jin, R. Steinigeweg, F. Heidrich-Meisner +2
We study the charge conductivity of the one-dimensional repulsive Hubbard model at finite temperature using the method of dynamical quantum typicality, focusing at half filling. Th…
First-principles modelling of magnetic excitations in Mn12
V. V. Mazurenko, Y. O. Kvashnin, Fengping Jin +3
We have developed a fully microscopic theory of magnetic properties of the prototype molecular magnet Mn12. First, the intra-molecular magnetic properties have been studied by mean…
Scaling of diffusion constants in the spin-1/2 XX ladder
R. Steinigeweg, F. Heidrich-Meisner, J. Gemmer +2
We study the dynamics of spin currents in the XX spin-1/2 ladder at finite temperature. Within the framework of linear response theory, we numerically calculate autocorrelation fun…
Nagaoka ferromagnetism in large-spin systems -Fermion and Boson systems--
Seiji Miyashita, Masao Ogata, Hans De Raedt
We study magnetic properties of itinerant quantum magnetic particles described by a generalized Hubbard model with large spin () which may be realized in optical lattices of…
