论文摘要
缺陷的相互作用会导致擦除现象。在此过程中，较低的对象被较高维的物体吸收和溶解。该现象非常笼统，并且具有广泛的含义，无论是宇宙学还是基本的。特别是，当遇到缺陷时，宇宙字符串，QCD通量管或基本字符串等所有类型的字符串都会被删除，无论是孤子或$ d $ brane deNconfine in confect而言。这导致了一种新型的宇宙弦分裂机制，并伴有引力和电磁辐射。基于连贯性和熵计数的参数表明，擦除概率非常接近一个，并且字符串永远不会通过切解层实现。我们通过对系统的数值模拟来确认这一点，该模拟有效地捕获了现象的本质：$ 2+1 $维度的二维问题是$ U（1）$ higgs型号的Nielsen-Operen涡流与内部的域墙壁之间的互动问题，而$ U（1）$ u（1）$ eguge Group是没有磁性的玻璃和磁性的。根据熵参数，在我们的模拟中，涡旋永远不会使其穿过墙壁。
The interaction of defects can lead to a phenomenon of erasure. During this process, a lower-dimensional object gets absorbed and dissolved by a higher-dimensional one. The phenomenon is very general and has a wide range of implications, both cosmological and fundamental. In particular, all types of strings, such as cosmic strings, QCD flux tubes, or fundamental strings, get erased when encountering a defect, either solitonic or a $D$-brane that deconfines their fluxes. This leads to a novel mechanism of cosmic string break-up, accompanied by gravitational and electromagnetic radiations. The arguments based on loss of coherence and the entropy count suggest that the erasure probability is very close to one, and strings never make it through the deconfining layer. We confirm this by a numerical simulation of the system, which effectively captures the essence of the phenomenon: a $2+1$-dimensional problem of interaction between a Nielsen-Olesen vortex of a $U(1)$ Higgs model and a domain wall inside which the $U(1)$ gauge group is unHiggsed and the magnetic flux is deconfined. In accordance with the entropy argument, in our simulation, the vortex never makes it across the wall.
