Constraints on ultracompact minihalos from extragalactic γ-ray background
Yupeng Yang, Lei Feng, Xiaoyuan Huang +3
It has been proposed that ultracompact minihalos (UCMHs) might be formed in earlier epoch. If dark matter consists of Weakly Interacting Massive Particles (WIMPs), UCMHs can be tre…
The Abundance of New Kind of Dark Matter Structures
Yupeng Yang, Xuelei Chen, Tan Lu +1
A new kind of dark matter structures, ultracompact minihalos (UCMHs) was proposed recently. They would be formed during the radiation dominated epoch if the large density perturbat…
New application of decomposition of U(1) gauge potential:Aharonov-Bohm effect and Anderson-Higgs mechanism
Jian-Feng Li, Yu Jiang, Wei-Min Sun +2
In this paper we study the Aharonov-Bohm (A-B) effect and Anderson-Higgs mechanism in Ginzburg-Landau model of superconductors from the perspective of the decomposition of U(1) gau…
New Constraints on Primordial Minihalo Abundance Using Cosmic Microwave Background Observations
Yupeng Yang, Xiaoyuan Huang, Xuelei Chen +1
It was proposed that the massive compact halo objects (MCHOs) would be produced during an earlier epoch of cosmology if the density perturbations are between and…
Calculation of bulk viscosity of QCD at zero temperature and finite chemical potential
Ming-Min Wang, Yu Jiang, Bin Wang +2
In this letter, based on Kubo's formula and the QCD low energy theorem, we propose a direct formula for calculating the bulk viscosity of QCD at finite chemical potential and z…
The Wigner solution of quark gap equation at nonzero current quark mass and partial restoration of chiral symmetry at finite chemical potential
Yu Jiang, Hao Gong, Wei-min Sun +1
According to the generally accepted phase diagram of QCD, at low temperature and high baryon number density the chiral phase transition of QCD is of first order and the co-existenc…
