对“通过非引力特征寻找拓扑缺陷暗物质”评论的答复
Reply to comment on "Searching for Topological Defect Dark Matter via Nongravitational Signatures"
摘要：
在Avelino、Sousa和Lobo [arXiv：1506.06028]的评论中，通过比较拓扑缺陷的动能与脉冲星的总能量，认为由于拓扑缺陷网络通过脉冲星而导致的脉冲星毛刺现象的起源面临着严重的困难。在这里，我们指出，拓扑缺陷可能会引发传统场景中的脉冲星故障，例如涡旋解钉扎。如果从拓扑缺陷传递的能量超过单个钉扎涡旋的激活能，这可能导致涡旋的雪崩解钉扎，从而导致脉冲星毛刺，因此毛刺事件所需的角动量和能量来源由脉冲星本身提供。事实上，这样一个过程的激活能可能非常小（与观测到的脉冲星旋转动能在故障开始时的增加相比，基本上为零）。通过拓扑缺陷进入脉冲星的核心，可能会发生涡旋的脱钉。
英文摘要：
In the comment of Avelino, Sousa and Lobo [arXiv:1506.06028], it is argued, by comparing the kinetic energy of a topological defect with the overall energy of a pulsar, that the origin of the pulsar glitch phenomenon due to the passage of networks of topological defects through pulsars is faced with serious difficulties. Here, we point out that topological defects may trigger pulsar glitches within traditional scenarios, such as vortex unpinning. If the energy transfer from a topological defect exceeds the activation energy for a single pinned vortex, this may lead to an avalanche of unpinning of vortices and consequently a pulsar glitch, and therefore the source of angular momentum and energy required for a glitch event is provided by the pulsar itself. Indeed, the activation energy for such a process can be very small (essentially zero compared with the observed increase in the pulsar's rotational kinetic energy at the onset of a glitch). The unpinning of a vortex by a topological defect may occur through the passage of the defect into the core of the pulsar.
