Circular Dichroism without absorption in isolated chiral dielectric Mie particles
Rafael S. Dutra, Felipe A. Pinheiro, Diney S. Ether +3
We demonstrate that an effect phenomenologically analogous to circular dichroism can arise even for dielectric and isotropic chiral spherical particles. By analyzing the polarimetr…

Probing the chirality of a single microsphere trapped by a focused vortex beam through their orbital period
Kainã Diniz, Tanja Schoger, Arthur L. Fonseca +6
When microspheres are illuminated by tightly focused vortex beams, they can be trapped in a non-equilibrium steady state where they orbit around the optical axis. By using the Mie-…
