In this figure, the electric dipole moment is represented by a positive charge (red dot) and a negative charge (blue dot) that are spatially separated. The quadrupole, made up of two opposing ...

Surprisingly, this property in its most basic form is related to the higher electric multipole moments." Revolutionary work in the 1990s and 2000s by Vanderbilt, King-Smith, Resta, Martin ...
