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…
Parametric resonance amplification of gravitational waves in dynamical Chern-Simons gravity
Han-Wen Hu, Chen Lan, Zong-Kuan Guo
Within the effective field theory of dynamical Chern-Simons (dCS) gravity, we study parametric resonance amplification of gravitational waves driven by an oscillating environmental…
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…
Nonminimally coupled quintessence with sign-switching interaction
Jia-Qi Wang, Rong-Gen Cai, Zong-Kuan Guo +3
We propose a new nonminimally coupled quintessence model to account for the late-time dark energy dynamics indicated by recent Dark Energy Spectroscopic Instrument (DESI) measureme…
Localized Steps toward ACT-Favored Inflation
Kai-Ge Zhang, Chengjie Fu, Jian-Feng He +1
Recent ACT measurements favor a scalar spectral index larger than the Planck value, posing a challenge to many single-field slow-roll inflation models. We show that a smooth, local…
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…
