Calculation record
Causal response of the specified local scalar Dirac equation.
The uniform background is a calculation, not an identified physical vacuum
or bound particle. Response modes belong to the same Dirac field. The flat
propagation control uses a finite numerical buffer before any boundary can
be reached; it introduces no physical compactification.
Research context
- Causal scalar response of the local Dirac equation
The written local scalar Dirac term has an exact retarded response about a specified uniform background, with two signed propagation channels, a conserved zero mode and a controlled static limit.
