标题： Dynamics of semi-superfluid fluxtubes in color-flavor locked quark matter

摘要： 在超高密度下，例如中子星的核心处，物质可能以色超导（CFL）相的形式存在，这是一种超流体。 这种相具有拓扑稳定的涡旋解，这些解在旋转的超流体中表现为携带角动量量子的局域化构型。 尽管这些涡旋具有拓扑稳定性，但在中子星密度下它们并不是系统的最低能量态，并会衰变为半超流体磁通管的三重态。 在这些会议记录中，我们报告了我们在Ginzburg-Landau方法中的数值研究进展，在此研究中我们调查了半超流体磁通管的晶格。 通过规范场存在的全局涡旋构型的受控衰变获得这些磁通管。 理解半超流弦构型的动力学对于中子星夸克物质核心超出核心边界处角动量传递非常重要，因为在该场景中似乎不是涡旋而是磁通管钉扎才是相关的机制。 显示英文摘要

摘要： At very high densities, as for example in the core of a neutron star, matter may appear in the color-flavor locked (CFL) phase, which is a superfluid. This phase features topologically stable vortex solutions, which arise in a spinning superfluid as localized configurations carrying quanta of angular momentum. Despite the topological stability of these vortices they are not the lowest energy state of the system at neutron star densities and decay into triplets of semi-superfluid fluxtubes. In these proceedings we report on the progress of our numerical study in the Ginzburg-Landau approach, where we investigate lattices of semi-superfluid fluxtubes. The fluxtubes are obtained through controlled decay of global vortex configurations in the presence of a gauge field. Understanding the dynamics of semi-superfluid string configurations is important in the context of angular momentum transfer from a quark matter core of a neutron star beyond the core boundary, since not vortex-, but fluxtube pinning seems to be the relevant mechanism in this scenario.
