Suppressed Quantum Effects of Weakly Coupled Waves
Yunjia Bao, Dhong Yeon Cheong, Nicholas L. Rodd +3
The paper analyzes why quantum signatures of weakly coupled waves such as axion dark matter and gravitational radiation are extremely hard to detect, showing that detector coarse‑g…
Searching Stochastic Gravitational Wave Background Landscape Across Frequency Bands
Yunjia Bao, Tore Boybeyi, Vuk Mandic +1
Gravitational wave (GW) astrophysics is entering a multi-band era with upcoming GW detectors, enabling detailed mapping of the stochastic GW background across vast frequencies. We…
Spectator Composes a Gravitational Canon: Spectator-field-triggered Phase Transition During Inflation and its Anisotropic Gravitational Wave Signals
Yunjia Bao, Keisuke Harigaya
We propose a general framework in which a phase transition is triggered during cosmic inflation by the slow-roll dynamics of a spectator field. The topological defects formed at th…
Anatomy of Parity-violating Trispectra in Galaxy Surveys
Yunjia Bao, Lian-Tao Wang, Zhong-Zhi Xianyu +1
Parity-violating interactions are ubiquitous phenomena in particle physics. If they are significant during cosmic inflation, they can leave imprints on primordial perturbations and…
Intrinsically Quantum Effects of Axion Dark Matter are Undetectable
Yunjia Bao, Dhong Yeon Cheong, Nicholas L. Rodd +3
Is the usual treatment of axion dark matter as a classical field reliable? We show that the answer is subtle: the axion field could well be in a quantum state that has no complete…
