Figure 2. Phase diagram in the /u — (iq plane for T = /U3 = /us = 0. The various phases separated by the solid lines are characterized by different non-vanishing diquark gaps Ai as indicated in the figure. In the non-superconducting phase quarks are present only above the dashed line. The + and signs indicate the sign of the electric charge density in the corresponding region. The dotted line corresponds to electrically neutral matter in the CFL phase.

Now, we discuss the role of electrical charge neutrality condition. If a macroscopic chunk of quark matter has nonzero net electrical charge density tiq, the total thermodynamical potential for the system should be given by... 

The average electrical charge density of the mixed phase is determined by the charge densities of its components taken in the proportion of the corresponding volume fractions. Thus,... 

Here F (r) is any force imposed by an external boundary condition such as a shear flow and p(r) is the electrical charge density at r. 

The interfacial capacitance increases with the DDTC concentration added. The relationship among potential difference t/ of diffusion layer, the electric charge density q on the surface of an electrode and the concentration c of a solution according to Gouy, Chapman and Stem model theory is as follows.

The existence of the strong form of chemisorption on the surface, that is, of the form in which a lattice electron or hole is localized near the chemisorbed particle, leads, among other things, to the appearance of a charge on the semiconductor surface. Denoting by surface electric charge density due to chemisorption we obtain, according to (7) and (9),...

A term used in electrostatic descriptions of ions to denote the continuous electric charge density [p(r)] surrounding an ionic species. On average, an ion will be surrounded by a spherically symmetrical distribution of counterions that form its ion atmosphere. See Hydration Atmosphere... 

In order to understand the diffuse layer in detail, we need to go back to the fnndamental eqnations of electrostatics due to J.C. Maxwell. The equation of interest relates the local electric field E(r) at the position vector r to the net local electric charge density p(r) ... 

The quantum mechanical derivation also explains the sign of the Zemach correction. The spreading of the magnetic and electric charge densities weakens the interaction and consequently diminishes hyperfine splitting in accordance with the analytic result in (11.4). 

The local electric charge density of the present theory can have either sign. In the photon model, however, the boundary conditions on the electric field cause... 

Recall that in the Navier-Stokes equation (6.4.1) m is the fluid density, assumed constant further on, whereas p is the electric charge density related as usual to the ionic concentrations as... 

The electrical charge densities of the membrane surface of channels 2 and 4 were lower than that of channel 1. Then the response behaviors to electrolytic substances were caused by lipid materials, the plasticizer and PVC. The channel 3 behaved as a negatively charged membrane due to ionization of carboxyl groups. 

There is a cause-effect relationship between electric charge density and electric held, represented by Eq. (10). Since pe = 0, it should follow that E = 0. Such trivial solution, however, cannot possibly represent a photon. There is another alternative. Induction Eqs. (8) and (9) relate to E and B so that, if B were an independent variable, variations of magnetic held could, in principle, induce an electric held. However, magnetic held B is conventionally ascribed to moving charges [66]. Again, pe = 0 forbids B, and a fortiori E. It seems that there is some violation of causality an electromagnetic held represented by E and B (effect) without a source pe (cause). 

The definition of electric charge density in Eq. (76) agrees with our opinion that 0 in Maxwell s equations represents charge neutrality (see Section HI) the simplest case is 5+ + S = 0. Also note that X/ defined by Eq. (74) is independent of pe thus allowing for the existence of a displacement current in the absence of electric charge, as also discussed in Section HI.
