Derives explicit expression for ω in the ω-effect from Takagi supermodes of a squeezed graviton bath produced by an axion cloud around a Kerr black hole.
Superradiant axion-like-particle clouds around rotating black holes can generate multimode squeezed graviton states with 10^6-10^7 correlated quanta showing polarization correlations and quantum-noise signatures potentially detectable by future interferometers.
Gravitons in different quantum states smear the light cone via operator treatment of Synge's world function, regularizing UV singularities in phi^3 and phi^4 one-loop diagrams with a 10^{-10} correction from primordial gravitons.
The noise spectrum an interferometer would see from quantum spacetime jitter is computed for vacuum, thermal, squeezed, and scalar-backreaction states; all are Planck-suppressed.
The paper formulates dark matter detection in matter-wave interferometers as an open-system problem using Schwinger-Keldysh effective field theory, revealing channel asymmetries and Bose/Pauli factors for elastic scattering.
