a, thin disk vortex oscillator which generated vortex beam. b, Mach-Zender interferometer which is used to detect the helical phase characteristics. In recent years, optical vortices have attracted ...
Recent advances in femtosecond optical vortices (FOVs)—characterized by helical wavefronts and high peak power—have enabled breakthroughs in attosecond vortex generation and 3D chiral microfabrication ...
In a new Nature Physics paper, researchers report the first experimental observation of the transverse Thomson effect, a key thermoelectric phenomenon that has eluded scientists since it was predicted ...
