恒磁场中荷电和中性矢量玻色子气体的各向异性物态方程。天体物理学意义
Anisotropic equation of state of charged and neutral vector boson gases in a constant magnetic field. Astrophysical implications
摘要：
我们得到了带电和中性矢量玻色子气体在恒定磁场中的压强和状态方程。磁场对系统施加的轴对称性将压力沿磁轴在平行和垂直方向上分开，这导致了各向异性状态方程。压力和能量密度的值与致密物体中费米气体的值相当。这为磁化玻色子星的存在提供了可能性。在某些条件下，垂直压力可能是负的，这对恒星的稳定性造成了限制。还讨论了负压的其他影响。
英文摘要：
We obtain the pressures and equations of state (EoS) of charged and neutral vector boson gases in a constant magnetic field. The axial symmetry imposed to the system by the field splits the pressures in the parallel and perpendicular directions along the magnetic axis, and this leads to anisotropic equations of state. The values of pressures and energy densities are in the order of those of Fermi gases in compact objects. This opens the possibility to the existence of magnetized boson stars. Under certain conditions, the perpendicular pressure might be negative imposing a bound to the stability of the star. Other implications of negative pressures are also discussed.
