Spin–orbit torque can drive auto-oscillations of propagating spin-wave modes in nano-constriction spin Hall nano-oscillators. These modes facilitate both long-range coupling and the possibility of ...

Quasi-phase matching (QPM) enhances nonlinear optical processes by compensating for phase mismatch, but traditional methods require permanent material modifications, limiting applicability in ...

A new study finds that an easily measurable brain wave shift of phase may be a universal marker of unconsciousness under general anesthesia. At the level of molecules and cells, ketamine and ...
