论文摘要
在磁场下，在磁场下，夸克异常磁矩（AMM）对Baryon Chemical势能 - 温度 - 温度$（μ_B-T）$平面中手性恢复和解反性相变的影响。发现Quark AMM扮演着相变向相变的作用，大夸克AMM会将相变的磁催化现象改变为整个$μ_b-t $平面中的反磁催化。对于固定磁场，临界温度$ T_C $和关键的Baryon化学势$μ_b^c $随夸克AMM降低。磁场越强，AMM的反催化效应变得越来越重要。对于一个小的AMM $κ=κ_1$，它显示了临界温度的磁性催化效应$ t_c $在消失的$μ_b$随着磁场的增加，以及（逆）磁性催化效果（临界Baryon化学势）$μ_b^c $在消失的$ t $下，$ t $ t $ taunce $ t $。在有限$ t $和$μ_b$的情况下，存在具有不同磁场的相变线的一些交叉点。对于大的AMM $κ=κ_2$，我们在整个$μ_b-t $平面中获得反向磁性催化效应，并且没有相位过渡线的交叉。
The effect of quark anomalous magnetic moment (AMM) to chiral restoration and deconfinement phase transitions in baryon chemical potential-temperature $(μ_B-T)$ plane under magnetic fields is investigated in frame of a Pauli-Villars regularized PNJL model. It's found that the quark AMM plays the role of inverse catalysis to the phase transitions, and large quark AMM will change the magnetic catalysis phenomena of phase transitions to inverse magnetic catalysis in the whole $μ_B-T$ plane. For a fixed magnetic field, the critical temperature $T_c$ and critical baryon chemical potential $μ_B^c$ decreases with quark AMM. The stronger the magnetic field is, the inverse catalysis effect of AMM becomes more important. For a small AMM $κ=κ_1$, it shows the magnetic catalysis effect for critical temperature $T_c$ at vanishing $μ_B$ with increasing magnetic field, and (inverse) magnetic catalysis effect for critical baryon chemical potential $μ_B^c$ at vanishing $T$ under (weak) strong magnetic field. At finite $T$ and $μ_B$, there exist some crossings of the phase transition lines with different magnetic field. For a large AMM $κ=κ_2$, we obtain the inverse magnetic catalysis effect in the whole $μ_B-T$ plane, and no crossings of phase transition lines happen.
