Non-minimally Coupled Running Curvaton for DESI-motivated Dynamical Dark Energy
Bichu Li, Lei-Hua Liu
Recent DESI BAO data combined with CMB and supernova measurements suggest a dynamical dark energy that can cross the phantom divide. We show that introducing a non-minimal coupling…

The backreaction effect of the sound speed resonance in DBI inflation
Bichu Li, Chao Chen, Bo Wang
We examine the backreaction effect of the enhanced small-scale scalar perturbations from the sound speed resonance (SSR) mechanism for primordial black hole formation in Dirac-Born…

The nonlinear equation of correlation function of galaxies in the expanding universe and the solution in linear approximation
Yang Zhang, Bichu Li
We present an analytic study of the density fluctuation of a Newtonian self-gravity fluid in the expanding universe with , which extends our previous work in the static…
