When light and electrons spin together

Phys.org  July 12, 2022 An international team of researchers (Germany, Spain, USA – research organization) has demonstrated how the coupling between intense lasers, the motion of electrons, and their spin influences the emission of light on the ultrafast timescale. They demonstrated how changes in the electron velocity can affect the electron dynamics in Na3Bi and that this effect can sometimes be detrimental to the generation of high-order harmonics. While this material is non-magnetic, the team has shown that the spin of the electrons is important for the dynamics, as it couples to the potential felt by the electrons, which is […]
