Tensor Perturbations from Bounce Inflation Scenario in f(Q) Gravity
Kun Hu, Tanmoy Paul, Taotao Qiu
In this paper, we construct a bounce inflation cosmological scenario in the framework of the modified symmetric teleparallel gravity, namely f(Q) theory, and investigate the tensor…
Generation of primordial black holes from an inflation model with modified dispersion relation
Taotao Qiu, Wenyi Wang, Ruifeng Zheng
A primordial black hole (PBH) is interesting to people for its ability of explaining dark matter as well as supermassive astrophysical objects. In the normal inflation scenario, th…
Searching for Signal of Primordial Black Hole from CMB Lensing and -ray Emissions
Xiu-Hui Tan, Yang-Jie Yan, Taotao Qiu +1
In this , we search for the signal of the primordial black holes (PBHs) by correlating the -ray emissions in the MeV energy band produced by the Hawking evapora…
Mimetic Curvaton
Xin-zhe Zhang, Lei-hua Liu, Taotao Qiu
In this paper, we investigate the primordial perturbations of inflation model induced from the multi-field mimetic gravity, where there are two field during inflation, and thus bot…
ADM formulation and Hamiltonian analysis of gravity
Kun Hu, Taishi Katsuragawa, Taotao Qiu
gravity is an extension of the symmetric teleparallel equivalent to general relativity. We demonstrate the Hamiltonian analysis of gravity with fixing the coincident…
Can the Quantization of Black Hole be detected?
Ruifeng Zheng, Taotao Qiu
As a mysterious celestial body predicted by General Relativity, black holes have been confirmed by observations in recent years. But there are still many unknown properties waiting…
