Endpoint Control of Thermodynamic Topological Classes for Fixed Charge \texorpdfstring{}{d}-dimensional Reissner--Nordström Black Holes in a Cavity

Rongrong Zhai

We study thermodynamic topological classes of -dimensional Reissner--Nordström (RN) black holes in a cavity at fixed charge. Starting from the reduced Euclidean action, we use t…

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,…

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…
