Control of magnons via ultrafast magnetization modulation
N. Singh, P. Elliott, J. K. Dewhurst +1
We demonstrate optical control of magnons using femtosecond laser pulses by performing ab-initio real-time time-dependent density functional theory (TDDFT) simulations. We predict…

A complete description of the magnetic ground state in spinel vanadates
Jyoti Krishna, N. Singh, S. Shallcross +4
Capturing the non-collinear magnetic ground state of the spinel vanadates AVO (A= Mn, Fe and Co) remains an outstanding challenge for state-of-the-art ab-initio methods. We…

Ultrafast demagnetization in bulk vs thin films: an ab-initio study
K. Krieger, P. Elliott, T. Müller +4
We report on {\it ab-initio} simulations of the quantum dynamics of electronic charge and spin when subjected to intense laser pulses. By performing separate calculations for a Ni…
