Probing the Perturbative Reheating History of Decaying Oscillatory Inflation with ACT Constraints

Li-Yang Chen, Rongrong Zhai, Feng-Yi Zhang

Precision measurements of the Cosmic Microwave Background (CMB) now offer a powerful probe of the unknown reheating epoch. In this work, we scrutinize a decaying oscillatory inflat…

Reconciling the ACT Preference in Gravity: Inflation and Reheating Constraints

Feng-Yi Zhang, Rongrong Zhai, Li-Yang Chen

Compared with the results of Planck-only analyses, recent measurements from the Atacama Cosmology Telescope (ACT) indicate a preference for a slightly bluer scalar spectral index,…

The odd-parity altermagnetism: A spin group study

Minghuan Zeng, Zheng Qin, Ling Qin +4

Following recent intensive studies on altermagnetism(ALM) characterized by non-relativistic even-parity spin splitting, realizing unconventional odd-parity magnetism has also attra…

Primordial black holes and scalar induced gravitational waves from sound speed resonance in non-minimal derivative coupling inflation model

Li-Shuai Wang, Qiong-Tao Xie, Li-Yang Chen

We investigate an inflationary model with a non-minimal derivative coupling, where the coupling function contains both constant and periodic components. On large scales, the model…

Frame-Dependence of the Hamilton-Jacobi Formalism for Inflation and Reheating in Non-Minimal Gravity

Feng-Yi Zhang, Li-Yang Chen, Rongrong Zhai

In this work, we investigate the Hamilton-Jacobi formalism for non-minimally coupled inflation, focusing on the methodological frame-dependence arising from its application in the…
