色超导介质中的感生磁
Induced Magnetism in Color-Superconducting Media
摘要：
致密星的致密核是实现色超导的天然介质。这类天体的一个共同特征是它们的强磁场，特别是所谓的磁星。在这次演讲中，我将讨论如何一个彩色超导核心可以产生或/和增强恒星磁场独立的磁流体动力发电机机制。在这种情况下，磁场发生器是胶子电流，其在强磁场存在下或在由中性和$β$平衡约束在介质中产生的配对应力下循环以稳定色超导体。
英文摘要：
The dense core of compact stars is the natural medium for the realization of color superconductivity. A common characteristic of such astrophysical objects is their strong magnetic fields, especially those of the so called magnetars. In this talk, I discuss how a color superconducting core can generate or/and enhance the stellar magnetic field independently of a magnetohydrodynamic dynamo mechanism. The magnetic field generator is in this case a gluonic current which circulates to stabilize the color superconductor in the presence of a strong magnetic field or under the pairing stress produced in the medium by the neutrality and $β$-equilibrium constraints.
