Resonance-Induced Sign Reversal of Optical Gradient Forces and Three-Dimensional Singularity Trapping
Jinsheng Lu, Soon Wei Daniel Lim, Federico Capasso
In atomic physics, tuning the light frequency across a resonance reverses the trapping force between bright and dark field regions, yet a unified analytical description of this pri…

Multidimensional optical singularities and their applications
Soon Wei Daniel Lim, Christina M. Spaegele, Federico Capasso
Optical singularities, which are positions within an electromagnetic field where certain field parameters become undefined, hold significant potential for applications in areas suc…
