Adiabatic magnon spectra with and without constraining field: Benchmark against an exact magnon spectrum
Simon Streib, Ramon Cardias, Manuel Pereiro +5
The spectrum of magnon excitations in magnetic materials can be obtained exactly from the transverse dynamic magnetic susceptibility, which is however in practice numerically expen…

Equation of motion and the constraining field in ab initio spin dynamics
Simon Streib, Vladislav Borisov, Manuel Pereiro +5
It is generally accepted that the effective magnetic field acting on a magnetic moment is given by the gradient of the energy with respect to the magnetization. However, in ab init…
