Thermal-acoustic fermionic dynamics and primordial perturbations in warm Yukawa inflation
Xi-Bin Li, Ke Fu, Ya-Ting Wang +2
We investigate fermion production and its cosmological consequences in a warm inflationary scenario with a Yukawa interaction between the inflaton field and Dirac fermions. Treatin…

Primordial electric fields before recombination in the early Universe
Xi-Bin Li
This work is a supplement on the previous research about primordial electromagnetic fields. In this work, three important problems are discussed: the evolution of primordial electr…

Fluctuation of the Hubble parameter
Xi-Bin Li, Hao-Feng Qin, Zhi-Song Zhang +1
We study the Hubble parameter in perturbed Friedmann universe and obtain an expression of the perturbed Hubble parameter . We derive the Hubble parameter po…
