Trajectory-Based Unveiling of Angular Momentum of Photons

Yongnan Li, Zhi-Cheng Ren, Ling-Jun Kong +2

The Heisenberg uncertainty principle suggests that it is impossible to determine the trajectory of a quantum particle in the same way as a classical particle. However, we may still…

Optical force on toroidal nanostructures: toroidal dipole versus renormalized electric dipole

Xu-Lin Zhang, S. B. Wang, Zhifang Lin +2

We study the optical forces acting on toroidal nanostructures. A great enhancement of optical force is unambiguously identified as originating from the toroidal dipole resonance ba…

Analytic derivation of electrostrictive tensors and their application to optical force density calculations

Wujiong Sun, S. B. Wang, Jack Ng +2

Using multiple scattering theory, we derived for the first time analytical formulas for electrostrictive tensors for two dimensional metamaterial systems. The electrostrictive tens…
