Skyrmionic Schrödinger cat states in monoaxial chiral magnets
Stefan Liscak, Andreas Haller, Andreas Michels +2
We study the low-energy excitation spectra of a spin-1/2 quantum Heisenberg model with a monoaxial Dzyaloshinskii-Moriya interaction. Using the density matrix renormalization group…

Spin-disorder-induced angular anisotropy in polarized magnetic neutron scattering
I. Titov, M. Bersweiler, M. P. Adams +14
We experimentally report a hitherto unseen angular anisotropy in the polarized small-angle neutron scattering (SANS) cross section of a magnetically strongly inhomogeneous material…

Stability and Nucleation of Dipole Strings in Uniaxial Chiral Magnets
Vladyslav M. Kuchkin, Nikolai S. Kiselev, Andreas Haller +3
We report on the stability of the magnetic dipole string (DS), a three-dimensional magnetic texture formed by two coupled Bloch points with opposite topological charges, separated…
