Quantum Anomalous Hall Effect in -Electron Kagome Systems: Chern Insulating States from Transverse Spin-Orbit Coupling
Imam Makhfudz, Mikhail Cherkasskii, Mohammad Alipourzadeh +5
The possibility of quantum anomalous Hall effect (QAHE) in two-dimensional kagome systems with -orbital electrons is studied within a multi-orbital tight-binding model. We conce…
Optically probing symmetry breaking in the chiral magnet Cu2OSeO3
R. B. Versteeg, I. Vergara, S. D. Schäfer +5
We report on the linear optical properties of the chiral magnet Cu2OSeO3, specifically associated with the absence of inversion symmetry, the chiral crystallographic structure, and…
Spectral properties of a narrow-band Anderson model
Steffen Schäfer, David E Logan
We consider single-particle spectra of a symmetric narrow-band Anderson impurity model, where the host bandwidth is small compared to the hybridization strength . Simple…
Dyson Equation Approach to Many-Body Greens Functions and Self-Consistent RPA, First Application to the Hubbard Model
Steffen Schäfer, Peter Schuck
An approach for particle-hole correlation functions, based on the so-called SCRPA, is developed. This leads to a fully self-consistent RPA-like theory which satisfies the -sum r…
