Sudden braking and turning with a two-field potential bump: primordial black hole formation

Chengjie Fu, Chao Chen

We investigate the amplification of curvature perturbations in a two-field inflation model featuring a Gaussian potential bump. When the inflaton encounters a potential bump along…

Missing one-loop contributions in secondary gravitational waves

Chao Chen, Atsuhisa Ota, Hui-Yu Zhu +1

We find several missing one-loop-order contributions in previous considerations about secondary gravitational waves induced at nonlinear order in cosmological perturbations. We con…

Toward Cosmological Standard Timers in Primordial Black Hole Binaries

Qianhang Ding

We propose that primordial black hole (PBH) binary systems can lead to standard timers in tracking the evolution of the Universe. Through gravitational waves from monochromatic PBH…

Induced gravitational waves from statistically anisotropic scalar perturbations

Chao Chen, Atsuhisa Ota

Scalar-induced gravitational waves (SIGWs) are attracting growing attention for probing extremely short-scale scalar perturbations via gravitational wave measurements. In this pape…
