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…
On the importance of heavy fields in pseudo-scalar inflation
Chong-Bin Chen, Ziwei Wang, Siyi Zhou
Pseudo-scalar inflation coupled with U(1) gauge fields through the Chern-Simons term has been extensively studied. However, new physics arising from UV theories may still influence…
Kinematic space for quantum extremal surface
An Gong, Chong-Bin Chen, Fu-Wen Shu
This paper investigates the entanglement entropy inequality and explores the presentation of mutual information and conditional mutual information in kinematic space. Specifically,…
Implications of multi-axion dark matter on structure formation
Chong-Bin Chen, Jiro Soda
Axions are candidates for dark matter in the universe.We develop an accurate Boltzmann code to calculate the linear growth of the plasma. As an interesting example, we investigate…
