Astrophysical Graviton Squeezing Can Be Hidden in the Far-Field
Cheng-Jun Fang, Zong-Kuan Guo, Zhen-Hong Lyu +3
While localized astrophysical sources can generate macroscopic graviton squeezing, their observable quantum signatures at far-field detectors remain unresolved. In this work, we in…

Fixing the Renormalization of Inflationary Loops via Ward Identities
Cheng-Jun Fang, Zong-Kuan Guo
Evaluating quantum loop corrections to curvature perturbations in non-attractor inflation presents theoretical ambiguities. A crucial aspect of this challenge lies in the unconstra…

Waveform stability of black hole ringdown with stochastic horizon structure
Han-Wen Hu, Cheng-Jun Fang, Zong-Kuan Guo
We examine the robustness of black hole ringdown to stochastic horizon-scale structure within an effective field framework in a proof-of-principle Schwarzschild setup.Consistent wi…
