Magnetoelectric Raman Force on Shear Phonons in a Frustrated van der Waals Bilayer Magnet

Wolfram Brenig

We show that the concept of coherent phonon generation by second order response to incident electric laser fields, which is a hallmark of pump-probe spectroscopy on conventional so…

Magnetostriction in the $J$ - $K$ - $I^$ model: Application of the numerical linked cluster expansion

Alexander Schwenke, Wolfram Brenig

We apply the numerical linked cluster expansion (NLCE) to study thermodynamic properties of the proximate Kitaev magnet $I^\pm$ -RuCl $_{3}$ on the honeycomb lattice in the presence of a…

Two-dimensional nonlinear dynamical response of the magnetoelectrically driven dimerized spin- $1 / 2$ chain

Wolfram Brenig

A study of the dynamical two-dimensional (2D) nonlinear response of the dimerized spin- $1 / 2$ chain to external electric fields is presented. The coupling of the spin system to th…
