Defining the Work Done on an Electromagnetic Field

The work done by an external electromagnetic field.

Ehrenfest's theorem is used to derive the rate of change of kinetic energy induced by an external field. The expression for the power is valid for any electromagnetic field in arbitrary gauge. We discuss the applicable conditions for the Mott-Davis and Moseley-Lukes form of the Kubo-Greenwood formula (KGF) for the electrical conductivity which has been implemented in ab initio codes. We show th...

Declarativeness: the work done by something else

Being declarative means that we do computer programming on higher levels of abstraction. This vague definition identifies declarativeness with the act of ignoring details, but it is a special case of abstraction. The unspecified part is some computational work. Automating computations and offloading mental processing are essentially the same concept, which is fundamental for both computational ...
