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.

A delivery ceremony has been held for the toroidal field magnet coil box - measuring 21 metres by 12 metres - at the Comprehensive Research Facility for Fusion Technology in Hefei, China. (Image: ...

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 ...
