Two-field cosmological phase transitions and gravitational waves in the singlet Majoron model
Youping Wan, Batool Imtiaz, Yi-Fu Cai
In the singlet Majoron model, we study cosmological phase transitions (PTs) and their resulting gravitational waves (GWs), in the two-field phase space, without freezing any of the…
The Effective Field Theory of nonsingular cosmology
Yong Cai, Youping Wan, Hai-Guang Li +2
In this paper, we explore the nonsingular cosmology within the framework of the Effective Field Theory(EFT) of cosmological perturbations. Due to the recently proved no-go theorem,…
Hearing the echoes of electroweak baryogenesis with gravitational wave detectors
Fa Peng Huang, Youping Wan, Dong-Gang Wang +2
We report on the first joint analysis of observational signatures from the electroweak baryogenesis in both gravitational wave (GW) detectors and particle colliders. With an effect…
Bounce Inflation Cosmology with Standard Model Higgs Boson
Youping Wan, Taotao Qiu, Fa Peng Huang +3
It is of great interest to connect cosmology in the early universe to the Standard Model of particle physics. In this paper, we try to construct a bounce inflation model with the s…
Nonsingular Cosmology from an Unstable Higgs Field
Robert H. Brandenberger, Yi-Fu Cai, Youping Wan +1
The observed value of the Higgs mass indicates an instability of the Higgs scalar at large energy scales, and hence also at large field values. In the context of early universe cos…
Single field inflation with modulated potential in light of the Planck and BICEP2
Youping Wan, Siyu Li, Mingzhe Li +3
The recently released BICEP2 data detected the primordial B-mode polarization in the Cosmic Microwave Background (CMB) map which strongly supports for a large tensor-to-scalar rati…
Constraints on Cosmological Models from Hubble Parameters Measurements
Wei Zheng, Hong Li, Jun-Qing Xia +3
In this paper, we study the cosmological constraints from the measurements of Hubble parameters--- data. Here, we consider two kinds of data: the direct probe fr…
Cosmology of the Spinor Emergent Universe and Scale-invariant Perturbations
Yi-Fu Cai, Youping Wan, Xinmin Zhang
A nonsingular emergent universe cosmology can be realized by a nonconventional spinor field as first developed in \cite{Cai:2012yf}. We study the mechanisms of generating scale-inv…
