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…
Airy-like hyperbolic shear polariton in high symmetry van der Waals crystals
Yihua Bai, Qing Zhang, Tan Zhang +7
Controlling light at the nanoscale by exploiting ultra-confined polaritons - hybrid light and matter waves - in various van der Waals (vdW) materials empowers unique opportunities…
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…
Generation of optical vortices imitating water vortices
Jun Yao, Yihua Bai, Yaqiang Qin +4
In optics, we can generate vortex beams using specific methods such as spiral phase plates or computer generated holograms. While, in nature, it is worth noting that water can prod…
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…
