Calculation record
Exact fixed and moving cavity-band matrix elements.
These are spatial operator controls. A fixed-band form factor is not
automatically a physical particle cross section or a charge assignment.
Research context
- Spatial and moving-cavity response
Exact oscillator matrix elements connect cumulative state counts to polarized spatial response and energy-transfer distributions, while moving scalar and Dirac modes show why a frozen cavity overlap is only one part of coupling.
