Non-singular Inflation-Dark Energy Unification Model Based on Loop Quantum Cosmology and Mass-Varying Neutrinos
Zhiming Shuai, Xiangdong Zhang
Unifying the early-universe inflationary paradigm with late-time cosmic acceleration, while resolving the initial Big Bang singularity, remains one of the most profound challenges…

Scalar superradiance in the charged black-bounce spacetimes
Zhiming Shuai, Xiangdong Zhang, Gui-Rong Liang
We numerically investigate the superradiant amplification effect of a charged scalar filed in the scattering experiment and the black hole bomb model in a charged black-bounce spac…

Scalar-Induced Gravitational Waves from Ghost Inflation and Parity Violation
Sebastian Garcia-Saenz, Yizhou Lu, Zhiming Shuai
We calculate the scalar-induced gravitational wave energy density in the theory of Ghost Inflation, assuming scale invariance and taking into account both the power spectrum- and t…
