中性双色超导体的色磁不稳定性和感生磁场

Chromomagnetic Instability and Induced Magnetic Field in Neutral Two-Flavor Color Superconductivity

Efrain J. Ferrer, Vivian de la Incera

摘要:

我们发现,中性双味色超导中存在的色磁不稳定性在中等密度下可以通过带电胶子的非均匀凝聚体的形成和相应的磁场的诱导而消除。结果表明,这种非均匀的基态是积极的青睐,比均匀的。中等密度的彩色超导体中自发产生的磁场对于具有强磁场的致密星体(如磁星)的天体物理学研究具有重要意义。

英文摘要:

We find that the chromomagnetic instability existing in neutral two- flavor color superconductivity at moderate densities is removed by the formation of an inhomogeneous condensate of charged gluons and the corresponding induction of a magnetic field. It is shown that this inhomogeneous ground state is energetically favored over a homogeneous one. The spontaneous induction of a magnetic field in a color superconductor at moderate densities can be of interest for the astrophysics of compact stellar objects exhibiting strong magnetic fields as magnetars.
