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 -- 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 -RuCl on the honeycomb lattice in the presence of a m…
Two-dimensional nonlinear dynamical response of the magnetoelectrically driven dimerized spin- chain
Wolfram Brenig
A study of the dynamical two-dimensional (2D) nonlinear response of the dimerized spin- chain to external electric fields is presented. The coupling of the spin system to th…
Two-dimensional nonlinear optical response of a spiral magnet
Wolfram Brenig
We study the dynamical response function relevant for two-dimensional coherent nonlinear optical spectroscopy of the antiferromagnetic frustrated - Heisenberg model o…
Finite temperature electric field induced two-dimensional coherent nonlinear spectroscopy in a Kitaev magnet
Wolfram Brenig, Olesia Krupnitska
We study electric field induced two-dimensional coherent nonlinear optical spectroscopy (2DCS) in a Kitaev magnet at finite temperature. We show that 2DCS is susceptible to both ty…
Jordan-Wigner approach to the frustrated spin one-half XXZ chain
T. Verkholyak, A. Honecker, W. Brenig
The Jordan-Wigner transformation is applied to study the ground state properties and dimerization transition in the chain. We consider different solutions of the me…
