Description
S2.1 (30’+5’) Non linear optics
S2.2 (30’+5’) Magnons and magnetic materials
S2.3 (30’+5’) Finite Systems
I will give an overview of the possible applications of point defects in quantum technologies, showing what are the quantity of interest that can be calculated and predicted, and I will discuss the main approaches that are currently exploited to achieve them.
In this talk I present an ab inito approach to calculate spin waves (magnons) based in the Bethe-Salpeter Equation.
The irradiation of a finite electronic system by an ultrafast XUV pulse can lead to the ultrafast creation of core-holes with strong subsequent electronic rearrangements. A standard theoretical tool to investigate such excitations that avoids the cost of the simulation of the XUV irradiation is to start the dynamics with an instantaneous core-hole excitation. In a recent series of papers...
