论文摘要
来自自发的洛伦兹违规机制的矢量场,即Bumblebee模型在$(1+2)D $ Minkowski时空的拓扑框架中进行了分析。采用$(1+2)d $ nonlinear Bumblebee vector物质字段动力学,其中包括Chern-Simons类型术语,Soliton State的向量版本或Vortex的拓扑。使用Nielsen-Operen程序是为了得出Lorentz-Violation矢量参数,该参数通过自发对称性破坏机制(非平凡的真空)来表征。我们与磁性涡流一样验证模型的稳定性,并注意到具有偏振方向的孤子模式可以与真空能量的局部各向异性有关。提出了运动和渐近行为的涡流方程。我们已经获得的是,洛伦兹对称违规的效果由时间般的大黄蜂矢量场真空吸尘器表达为在无限宇宙中的固定点$ r_0 $的脉冲,或作为$ r_0 $的屏障,可以在宇宙中具有宇宙的边界,如果是Bumblebee vector field Vield Vacuum具有空间式的特征。我们还通过传播器分析了频谱,我们注意到拓扑质量也对动态质量杆也有贡献。我们得到Chern-Simons类型项实际上表明该场的“速度”使渐近极限饱和,并且Vortex Core不能为尺寸为零。
A vector field coming from spontaneous Lorentz violation mechanism, namely Bumblebee model is analysed in a topological framework in a $(1+2)D$ Minkowski space-time. Taking a $(1+2)D$ nonlinear Bumblebee vector matter field dynamics where we include topological like Chern-Simons type terms, a vector version of a soliton state, or vortex was found. The Nielsen-Olesen procedure was used in order to derive a Lorentz-violation vector parameter which characterizes, via Spontaneous Symmetry Breaking mechanism, the non-trivial vacuum. We verify the stability of the model as much as the magnetic vortex, and noticed that the soliton modes with polarized direction generated can be associated with local anisotropy of vacuum energy. The vortex equations of motion and the asymptotic behaviour is presented. We have obtained that the effect of the Lorentz symmetry violation expressed by the a time-like Bumblebee vector field vacuum could be shown as kind of pulse at a fixed point $r_0$ in a limitless universe, or as a barrier at $r_0$ which can represent a boundary in the universe, if the Bumblebee vector field vacuum has space-like characteristic. We also analyse the spectrum via propagators where we note that the topological mass contributes as well to the dynamical mass poles. We obtain that the Chern-Simons type terms, in fact, indicates the "speed" of the field to saturate the asymptotic limit and that the vortex core can not be dimension zero.
