Introduction of Vacuum Fields to Cavity with Diffraction Loss

This paper establishes a rigorous quantum optical framework for analyzing diffraction-induced vacuum field injection in DECIGO's Fabry-Perot cavities, demonstrating that while such losses slightly increase radiation pressure noise, cavity detuning combined with homodyne detection and optical-spring locking can effectively mitigate these effects to enhance the detector's sensitivity to primordial gravitational waves.
