The dynamics of skyrmion shrinking
Frederik Austrup, Wolfgang Häusler, Michael Lau +1
When magnetic skyrmions decay, their size in real space decreases in a finite time before they eventually collapse. We construct an effective continuum model and use its dynamics t…
Driven Bose-Hubbard Model with a Parametrically Modulated Harmonic Trap
N. Mann, M. Reza Bakhtiari, F. Massel +2
We investigate a one-dimensional Bose-Hubbard model in a parametrically driven global harmonic trap. The delicate interplay of both the local atom interaction and the global drivin…
Spin-vibronics in interacting nonmagnetic molecular nanojunctions
S. Weiss, J. Brüggemann, M. Thorwart
We show that in the presence of ferromagnetic electronic reservoirs and spin-dependent tunnel couplings, molecular vibrations in nonmagnetic single molecular transistors induce an…
Iterative path integral summation for nonequilibrium quantum transport
S. Weiss, R. Hützen, D. Becker +3
We have developed a numerically exact approach to compute real-time path integral expressions for quantum transport problems out of equilibrium. The scheme is based on a determinis…
Quantum noise properties of multiphoton transitions in driven nonlinear resonators
V. Leyton, V. Peano, M. Thorwart
We investigate the quantum noise properties of a weakly nonlinear Duffing resonator in the deep quantum regime, where only few quanta are excited. This regime is dominated by the a…
Iterative summation of path integrals for nonequilibrium molecular quantum transport
R. Hützen, S. Weiss, M. Thorwart +1
We formulate and apply a nonperturbative numerical approach to the nonequilibrium current, , through a voltage-biased molecular conductor. We focus on a single electronic lev…
