有旋转和磁场存在下的荷电ρ超导体
Charged rho superconductor in the presence of magnetic field and rotation
摘要：
本文主要在三味Nambu-Jona-Lasino模型下研究了在平行磁场和转动条件下荷电ρ超导体的可能性。通过与以往研究带电π超流体（CPS）相似的方案，发现CRS在Minkovski空间和弯曲空间中对Schwinger相的选择都是有利的。由于内部自旋结构的稳定性，对于给定的大磁场，荷电ρ开始以比荷电π更小的角速度阈值凝聚。即使是轴向矢量介子凝聚也被检查--结论是CRS是强磁场和快速旋转下的鲁棒基态，其实际上维持非常大的角速度。
英文摘要：
In this work, we mainly explore the possibility of charged rho superconductor (CRS) in the presence of parallel magnetic field and rotation within three-flavor Nambu--Jona-Lasino model. By following similar schemes as in the previous studies of charged pion superfluid (CPS), the CRS is found to be favored for both choices of Schwinger phase in Minkovski and curved spaces. Due to the stability of the internal spin structure, charged rho begins to condensate at a smaller threshold of angular velocity than charged pion for the given large magnetic fields. Even the axial vector meson condensation is checked -- the conclusion is that CRS is the robust ground state at strong magnetic field and fast rotation, which actually sustains to very large angular velocity.
