我们调查的影响，涡核变形时，涡相互接近。作为这些涡核变形的结果，涡涡相互作用有效地获得一个有吸引力的组件，导致各种典型的涡模式的系统与非单调排斥吸引力的相互作用，如条纹，条纹等的核心变形是各向异性的，可以诱导挫折的涡涡相互作用。反过来，这种挫折产生的涡流图案，这是分析在存在额外的随机钉扎，作为钉扎强度的函数的影响。这一分析可应用于多带超导体中的涡旋或玻色-爱因斯坦凝聚体中的涡旋。
We investigate the effects related to vortex core deformations when vortices approach each other. As a result of these vortex core deformations, the vortex-vortex interaction effectively acquires an attractive component leading to a variety of vortex patterns typical for systems with non-monotonic repulsive-attractive interaction, such as stripes, labyrinths, etc. The core deformations are anisotropic and can induce frustration in the vortex-vortex interaction. In turn, this frustration has an impact on the resulting vortex patterns, which are analyzed in the presence of additional random pinning, as a function of the pinning strength. This analysis can be applicable to vortices in multiband superconductors or to vortices in Bose-Einstein condensates.
