High-order harmonic generation in solid
G. P. Zhang, Y. H. Bai
High harmonic generation (HHG) has unleashed the power of strong laser physics in solids. Here we investigate HHG from a large system, solid C, with 240 valence electrons en…
Manifestation of intra-atomic 5d6s-4f exchange coupling in photoexcited gadolinium
G. P. Zhang, T. Jenkins, M. Bennett +1
Intra-atomic exchange couplings (IEC) between and electrons are ubiquitous in rare-earth metals and play a critical role in spin dynamics. However, detecting them in re…
Laser-induced ultrafast demagnetization time and spin moment in ferromagnets: First-principles calculation
G. P. Zhang, M. S. Si, Thomas F. George
When a laser pulse excites a ferromagnet, its spin undergoes a dramatic change. The initial demagnetization process is very fast. Experimentally, it is found that the demagnetizati…
Hot spin spots in the laser-induced demagnetization
M. S. Si, G. P. Zhang
Laser-induced femtosecond magnetism or femtomagnetism simultaneously relies on two distinctive contributions: (a) the optical dipole interaction (ODI) between a laser field and a m…
