In a 1-D or 2-D crystal below the Peierls temperature, standing waves named for density and this quantity are formed.
In a 1-D or 2-D crystal below the Peierls temperature, standing waves named for density and this quantity are formed. This quantity's density is multiplied by the speed of light in the time-like component of a four-vector which is symbolized J. The flux of the polarization density through a surface equals the "bound" value of this quantity enclosed within the surface. This quantity's conservation is expressed by a continuity equation derived by applying the divergence theorem to (*) Ampere's Law. The quantization of this quantity was demonstrated in an experiment where Robert Millikan studied the motion of oil droplets. The force between "point" examples of this quantity is given by Coulomb's Law. For 10 points, what electrical quantity is thus measured in Coulombs?
