In his later life, Bardeen remained active in academic research, during which time he focused on understanding the flow of electrons in charge density waves (CDWs) through metallic linear chain compounds.
Electrostatics In free space the Laplace equation of any electrostatic potential must equal zero since ρ (charge density) is zero in free space.
Because of the small size of hydrogen relative to other atoms and molecules, the resulting charge, though only partial, represents a large charge density.
Graphene edges provide significantly higher charge density and reactivity than the basal plane, but they are difficult to arrange in a three-dimensional, high volume-density geometry.
If both sides of this equation are divided by the volume of this small piece of the charge distribution dV, the result is: : where f is the force density (force per unit volume) and ρ is the charge density (charge per unit volume).
In applications one also has to describe how the free currents and charge density behave in terms of E and B possibly coupled to other physical quantities like pressure, and the mass, number density, and velocity of charge-carrying particles.
