Phenomenology of Spillway Preheating: Equation of State and Gravitational Waves
Gareth Mansfield, JiJi Fan, Qianshu Lu
In the canonical tachyonic resonance preheating scenario, only an order one fraction of energy density in the inflaton is transferred to radiation, due to backreaction effects. One…
Constraints on photon mass and dark photon from the Jovian magnetic field
Shi Yan, Lingfeng Li, JiJi Fan
The Jovian magnetic field, being the strongest and largest planetary one in the solar system, could offer us new insights into possible microscopic scale new physics, such as a non…
Probing New Physics with High-Redshift Quasars: Axions and Non-standard Cosmology
Chen Sun, Manuel A. Buen-Abad, JiJi Fan
The Hubble diagram of quasars, as candidates to ``standardizable" candles, has been used to measure the expansion history of the Universe at late times, up to very high redshifts (…
New inflationary probes of axion dark matter
Xingang Chen, JiJi Fan, Lingfeng Li
If a light axion is present during inflation and becomes part of dark matter afterwards, its quantum fluctuations contribute to dark matter isocurvature. In this article, we introd…
