Sensitivity of Space-based Gravitational-Wave Interferometers to Ultralight Bosonic Fields and Dark Matter
Jiang-Chuan Yu, Yue-Hui Yao, Yong Tang +1
Ultralight bosonic fields (ULBFs) are predicted by various theories beyond the standard model of particle physics and are viable candidates of cold dark matter. There have been inc…
Signatures of Ultralight Bosons in Compact Binary Inspiral and Outspiral
Yan Cao, Yong Tang
Ultralight bosons are well-motivated particles from various physical and cosmological theories, and can be spontaneously produced during the superradiant process, forming a dense h…
Constraining deviations from spherical symmetry using -metric
Hrishikesh Chakrabarty, Yong Tang
The -spacetime metric is a static and axially symmetric vacuum solution of the Einstein equation. This spacetime represents a naked singularity and it has an extra parameter $…
On Conformal Transformation with Multiple Scalar Fields and Geometric Property of Field Space with Einstein-like Solutions
Yong Tang, Yue-Liang Wu
Multiple scalar fields appear in vast modern particle physics and gravity models. When they couple to gravity non-minimally, conformal transformation is utilized to bring the theor…
Inflation in gauge theory of gravity with local scaling symmetry and quantum induced symmetry breaking
Yong Tang, Yue-Liang Wu
Motivated by the gauge theory of gravity with local scaling symmetry proposed recently in 1712.04537 and 1506.01807, we investigate whether the scalar field therein can be responsi…
