How to Measure and Model Light-Induced Spin Transfer
Sinéad A. Ryan, Mohamed F. Elhanoty, Anya Grafov +13
Femtosecond laser light can transfer spin angular momentum between magnetic subspecies that exhibit hybridized valence bands within an alloy or compound, and represents the fastest…

How quantum selection rules influence the magneto-optical effects of driven, ultrafast magnetization dynamics
Mohamed F. Elhanoty, Olle Eriksson, Chin Shen Ong +1
Ultrafast magnetization dynamics driven by ultrashort pump lasers is typically explained by changes in electronic populations and scattering pathways of excited conduction electron…

Photo-induced Hidden Phase of 1T-TaS2 with Tunable Lifetime
Pierre-Adrien Mante, Chin Shen Ong, Daniel Finkelstein Shapiro +3
Phase transitions are ubiquitous, appearing at every length scale from atoms to galaxies. In condensed matter, ultrafast laser pulses drive materials to highly non-equilibrium cond…
