Birefringence Tomography for Axion Cloud
Yifan Chen, Chunlong Li, Yosuke Mizuno +5
An axion cloud surrounding a supermassive black hole can be naturally produced through the superradiance process. Its existence can be examined by the axion induced birefringence e…

Primordial black holes and gravitational waves from resonant amplification during inflation
Zihan Zhou, Jie Jiang, Yi-Fu Cai +2
We present a new realization of the resonant production of primordial black holes as well as gravitational waves in a two-stage inflation model consisting of a scalar field ϕwith a…

Probing new physics with multi-vacua quantum tunnelings beyond standard model through gravitational waves
Zihan Zhou, Jun Yan, Andrea Addazi +3
We report on a novel phenomenon of particle cosmology, which features specific cosmological phase transitions via quantum tunnelings through multiple vacua. The latter is inspired…
