Finite temperature second harmonic generation in Kitaev magnets
Olesia Krupnitska, Wolfram Brenig
We study electric field induced second harmonic generation (2HG) in the Kitaev model. This frustrated magnet hosts a quantum spin-liquid, featuring fractionalization in terms of mo…
Fractionalized Excitations Probed by Ultrasound
A. Hauspurg, S. Zherlitsyn, T. Helm +8
In this work, we study magnetoelastic interactions by means of ultrasound experiments in -RuCl -- a prototypical material for the Kitaev spin model on the honeycomb lattice,…
Series expansion studies of the --Heisenberg bilayer
Erik Wagner, Wolfram Brenig
We study a bilayer of the frustrated - Heisenberg-model on the square lattice. Starting from the dimer limit at strong interlayer coupling, we perform series expansions u…
Numerical interchain mean-field theory for the specific heat of the bimetallic ferromagnetically coupled chain compound MnNi(NO)(en) (en = ethylenediamine)
Andreas Honecker, Wolfram Brenig, Maheshwor Tiwari +3
We present a detailed study of the field-dependent specific heat of the bimetallic ferromagnetically coupled chain compound MnNi(NO)(en), en = ethylenediamine. For this…
Heat transport of the kagomé Heisenberg quantum spin liquid candidate YCu(OH)Br: localized magnetic excitations and spin gap
Xiaochen Hong, Mahdi Behnami, Long Yuan +5
The spin-1/2 kagomé Heisenberg antiferromagnet is generally accepted as one of the most promising two-dimensional models to realize a quantum spin liquid state. Previous experiment…
Spinless fermions in a gauge theory on the triangular ladder
Wolfram Brenig
A study of spinless matter fermions coupled to a constrained lattice gauge theory on a triangular ladder is presented. The triangular unit cell and the ladder geom…
