Dipole toroidal modes are a unique set of excitations that are predicted to occur in various physical systems, ranging from atomic nuclei to metamaterials. What characterizes these excitations, or ...

Magnetic and electric dipoles, objects with two oppositely charged ends, have a similar symmetrical structure. One might thus assume that they exhibit similar internal structures and physical states.

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Recently, a major breakthrough in the field of optical toroidal vortices has been achieved and published in ...

A demonstration of continuous sum-frequency generation of visible light in a microscopic silica resonator could provide a light source for on-chip silicon photonics and applications in the UV. The ...

The chemical interactions between suspended colloidal particles and a solute can induce the particles to self-propel, a phenomenon known as autophoresis. Studies of autophoretic motion have so far ...
