Topological response of the anomalous Hall effect in MnBi2Te4 due to magnetic canting

S. -K. Bac, K. Koller, F. Lux +15

Three-dimensional (3D) compensated MnBi2Te4 is antiferromagnetic, but undergoes a spin-flop transition at intermediate fields, resulting in a canted phase before saturation. In thi…

Momentum dependence of the topological susceptibility with overlap fermions

Yoshiaki Koma, Ernst-Michael Ilgenfritz, Karl Koller +4

Knowledge of the derivative of the topological susceptibility at zero momentum is important for assessing the validity of the Witten-Veneziano formula for the eta' mass, and likewi…

Topological Structure of the QCD Vacuum Revealed by Overlap Fermions

E. -M. Ilgenfritz, K. Koller, Y. Koma +2

Overlap fermions preserve a remnant of chiral symmetry on the lattice. They are a powerful tool to investigate the topological structure of the vacuum of Yang-Mills theory and full…

Vacuum structure revealed by over-improved stout-link smearing compared with the overlap analysis for quenched QCD

E. -M. Ilgenfritz, D. Leinweber, P. Moran +3

A detailed comparison is made between the topological structure of quenched QCD as revealed by the recently proposed over-improved stout-link smearing in conjunction with an improv…

The chiral transition on a 24^3x10 lattice with N_f=2 clover sea quarks studied by overlap valence quarks

V. Weinberg, E. -M. Ilgenfritz, K. Koller +4

Overlap fermions are particularly well suited to study the finite temperature dynamics of the chiral symmetry restoration transition of QCD, which might be just an analytic crossov…

Localization of overlap modes and topological charge, vortices and monopoles in SU(3) LGT

E. -M. Ilgenfritz, K. Koller, Y. Koma +4

We present selected recent results of the QCDSF collaboration on the localization and dimensionality of low overlap eigenmodes and of the topological density in the quenched SU(3)…
