Title [sv]
Teori för ultra-snabba laser-inducerade magnetiska processer
Title [en]
Theory of Ultrafast Laser-Induced Magnetic Processes
Abstract [en]
Employing ultrashort light pulses with durations of atto- to femto-seconds to probe the entangled dynamics of a material’s spin, orbital, and lattice degrees of freedom has led to exciting discoveries, to mention, for example, ultrafast demagnetization, THz-radiation-induced superconductivity, laser-imparted magnetization and all-optical magnetization switching.¬†¬†In spite of these exciting discoveries, applicable theory frameworks that can describe the dynamical non-equilibrium interaction of a material´s spin, orbital, and lattice degrees of freedom with such intensive, short radiation pulses are largely missing.Here we propose to develop such fundamental theoretical modeling, comprising both analytical and first-principles theory. Our specific aim is to treat ultrafast-laser-induced magnetic phenomena, such as the magnetization that can be induced by short laser pulses, to develop theory for all-optical magnetization switching, modeling of femtosecond laser-generated spin currents, and develop ab initio calculations for spectroscopy of magnetic materials measured with brilliant radiation in the as-yet not much explored extreme ultraviolet regime.The outcomes of the here-proposed fundamental study will expand our understanding of fast laser-induced processes and may have important consequences for future applications, such as ultrafast magnetic recording and information processing technologies.
