Spin-momentum locked interaction between guided photons and surface electrons in topological insulators
Siyuan Luo, Li He, Mo Li
The propagation of electrons and photons can respectively have the spin-momentum locking effect which correlates the spin with the linear momentum. For the surface electrons in thr…
Picosecond all-optical switching of magnetic tunnel junctions
Jun-Yang Chen, Li He, Jian-Ping Wang +1
Control of magnetism without using magnetic fields enables large-scale integration of spintronic devices for memory, computation and communication in the beyond-CMOS era. Mechanism…
The role of electron and phonon temperatures in the helicity-independent all-optical switching of GdFeCo
Jon Gorchon, Richard B. Wilson, Yang Yang +6
Ultrafast optical heating of the electrons in ferrimagnetic metals can result in all-optical switching (AOS) of the magnetization. Here we report quantitative measurements of the t…
Optomechanical measurement of photon spin angular momentum and optical torque in integrated photonic devices
Li He, Huan Li, Mo Li
Photons carry linear momentum, and spin angular momentum when circularly or elliptically polarized. During light-matter interaction, transfer of linear momentum leads to optical fo…
