Magnetic energy per particle in constant current density

Magnetic energy per particle in constant current density

We assume a constant current density in a homogeneous one-component plasma of infinite extent and calculate the resulting magnetic energy per particle. Our starting point is the conserved approximately relativistic (Darwin) energy for a system of electromagnetically interacting particles that arises from the neglect of radiation. For the idealized model of a homogeneous one-component plasma the...

Correlation energy per particle from the coupling-constant integration

The adiabatic connection can be used in density functional theory to define the unknown ~exchange and! correlation density functional. Using conventional wave-function techniques, accurate estimates of thus defined ~exchange and! correlation energy densities can be obtained for specified systems. In this paper, numerical results are presented for the He and the Be atom, as well as the isoelectr...

Subsystem functionals in density-functional theory: Investigating the exchange energy per particle

Density per particle as a descriptor of Coulombic systems.

It is shown that for finite Coulombic systems the density per particle, final sigma identical with rho/N, determines the value of any observable quantity. The associated variational principle is derived.
