Nonlinear optical quantum theory of demagnetization in L1 FePt and FePd
G. P. Zhang, Y. H. Bai, Thomas F. George
It is now well established that a laser pulse can demagnetize a ferromagnet. However, for a long time, it has not had an analytic theory because it falls into neither nonlinear opt…
Spin-phonon dispersion in magnetic materials
Mingqiang Gu, Y. H. Bai, G. P. Zhang +1
Microscopic coupling between the electron spin and the lattice vibration is responsible for an array of exotic properties from morphic effects in simple magnets to magnetodielectri…
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…
Laser-induced ultrafast transport and demagnetization at the earliest time: First-principles and real-time investigation
G. P. Zhang, Y. H. Bai, T. Jenkins +1
Here we carry out a first-principles time-dependent calculation to investigate how fast electrons actually move under laser excitation and how large the electron transport affects…
Generating high-order optical and spin harmonics from ferromagnetic monolayers
G. P. Zhang, M. S. Si, M. Murakami +2
High-order harmonic generation (HHG) in solids has entered a new phase of intensive research, with envisioned band-structure mapping on an ultrashort time scale. This partly benefi…
Understanding all-optical spin switching: Comparison between experiment and theory
G. P. Zhang, M. Murakami, M. S. Si +2
Information technology depends on how one can control and manipulate signals accurately and quickly. Transistors are at the core of modern technology and are based on electron char…
First-principles and model simulation of all-optical spin reversal
G. P. Zhang, Z. Babyak, Y. Xue +2
All-optical spin switching is a potential trailblazer for information storage and communication at an unprecedented fast rate and free of magnetic fields. However, the current wisd…
