Complete scalar Born vertices and finite-window frequency accounting.

Research context

  • Frequency accounting for scalar Born response

    Complete scalar vertices remove the negative-frequency resonant Born channel for positive incoming waves, while a finite-time positive preparation can retain a nonresonant response; the distinction follows from spatial momentum, frequency and both angular contractions.
