Misalignment production of isotropized vector dark matter?
Chong-Bin Chen
We present dark matter production by the misalignment mechanism of a multi-vector condensate through kinetic coupling during inflation. We impose isotropized background vector fiel…
Scalar-induced gravitational waves from inflation with symmetry breaking
Chong-Bin Chen, Jia-Xi Feng, Fu-Wen Shu +1
We investigate scalar-induced gravitational waves (SIGWs) in an inflationary model with symmetry breaking, in which charged scalar fields are coupled to an isotropic triplet of Abe…
Inflation with vector fields revisited: non-Gaussianities
Chong-Bin Chen
{We revisit the resulting bispectrum of inflation with kinetic-coupled vector fields by organizing the dynamics in terms of , which measures the vector kinetic contribution rela…
Bound-State Resonances of Schwarzschild-de Sitter Black Holes: Analytic Treatment
Qi-Dong Chen, Chong-Bin Chen, Guo-Qing Huang +2
Inspired by Mashhoon's framework connecting black hole quasi-normal modes (QNMs) to bound-state resonances in inverted potentials, Vlkel's recent numerical analysi…
Primordial black holes with anisotropic hair
Chong-Bin Chen, Bai-Xin An, Fu-Wen Shu
A mechanism for generating anisotropic enhancements of the curvature perturbation through a vector field is proposed. We find that when the mixing between the inflaton perturbation…
Inflation with vector fields revisited: heavy entropy perturbations and primordial black holes
Chong-Bin Chen
We revisit inflation coupled with vector fields employing kinetic coupling in the comoving gauge. It is known that there is a cumulative effect on the curvature power spectr…
