Momentum space entanglement of four fermion field theory
Weijun Kong, Qing Wang
Momentum space entanglement of four fermion field theory is calculated from the Wilsonian effective action pertubatively using replica trick, local terms in low energy effective ac…

Primordial black holes from the perturbations in the inflaton potential in peak theory
Qing Wang, Yi-Chen Liu, Bing-Yu Su +1
The primordial black hole (PBH) is an effective candidate for dark matter. In this work, the PBH abundance is calculated in peak theory, with one or two perturbations in the in…
