Anyonic Haldane insulator in one dimension
Florian Lange, Satoshi Ejima, Holger Fehske
We demonstrate numerically the existence of a nontrivial topological Haldane phase for the one-dimensional extended (-) Hubbard model with a mean density of one particle per…
A light induced metastable magnetic texture uncovered by in-situ Lorentz microscopy
Tim Eggebrecht, Marcel Möller, J. Gregor Gatzmann +7
Magnetic topological defects, including vortices and Skyrmions, can be stabilized as equilibrium structures by tuning intrinsic magnetic interactions and stray field geometries. He…
Discontinuous transitions in globally coupled potential systems with additive noise
Rüdiger Kürsten, Ulrich Behn
An infinite array of globally coupled overdamped constituents moving in a double-well potential with -th order saturation term under the influence of additive Gaussian white noi…
Symmetry-breaking oscillations in membrane optomechanics
C. Wurl, A. Alvermann, H. Fehske
We study the classical dynamics of a membrane inside a cavity in the situation where this optomechanical system possesses a reflection symmetry. Symmetry breaking occurs through su…
Dynamic Stark effect, light emission, and entanglement generation in a laser-driven quantum optical system
D. Pagel, A. Alvermann, H. Fehske
We calculate the emission spectra, the Glauber function, and the entanglement of formation for a few two-level emitters coupled to a single cavity mode and subject to an…
Microscopic theory of electron absorption by plasma-facing surfaces
Franz X. Bronold, Holger Fehske
We describe a method for calculating the probability with which the wall of a plasma absorbs an electron at low energy. The method, based on an invariant embedding principle, expre…
