几何约束下存在拓扑结构的费米子

Fermions in the presence of topological structures under geometric constrictions

D. Bazeia, A. Mohammadi, D. C. Moreira

摘要:

在这项工作中,我们研究了费米子与二维时空中的扭结结构相互作用的频谱的修改。我们考虑了费米子与产生非平凡内部结构的标量场之间的Yukawa耦合,并研究了费米子谱如何随控制扭结构型和Yukawa耦合的参数而变化。我们考虑的模型,使扭结状的解决方案的内部结构,以响应存在的几何收缩,并显示费米子光谱也可能出现直接影响的收缩。主要结果是当前的兴趣,并可能被用来提出建设的电子设备能够产生新的影响,在纳米尺度。

英文摘要:

In this work we study modifications of the spectrum of fermions interacting with kinklike structures in two-dimensional spacetime. We consider the Yukawa coupling between fermions and scalar fields that engender nontrivial internal structure and investigate how the fermion spectra change in terms of the parameters that control the kinklike configuration and the Yukawa coupling. We consider models that allow the internal structure of the kinklike solution to respond to the presence of a geometrical constriction, and show the fermion spectra may also appear directly affected by the constriction. The main results are of current interest and may be used to propose the construction of electronic devices capable of engendering new effects at the nanometric scale.
