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…
