论文摘要
Vortons是扩展的超导环，假设可以在宇宙学中发挥作用，甚至可能与高能量的宇宙射线具有重要意义。其中一些对象能够限制在对象\ cite {witten}的核心中变得无质量的费米子，\ cite {vorton3}。这些费米子以芯子的速度轻速传播，可能会产生大电流而不会耗散。这引起了对缺陷中这些电流的发电机制的兴趣。此处通过研究这些物体的反光电选择效应，即，通过扩展的缺陷而导致光子或巨大的玻色子的吸收来分析这个问题。当前工作的另一个动机是，在凝结的问题上存在讨论涡流在宏观马格努斯力中的作用，而涡流在某些类型的超氟或超导体中经历的。讨论是关于主要力的主要力来自对象或环境对物体中界状态的影响，这可能引起光谱流，从而导致有效的宏观力量\ cite \ cite {pelea1}，\ cite {pelea2}，\ cite {pelea3}。在不声称此处描述的结果中，在冷凝物质的背景下是结论性的，这项工作对Vortons与Fermions相互作用的Vortons的这两个效应进行了比较。
Vortons are extended superconducting rings, which hypothetically may play a role in cosmology and even may have significance in connection with cosmic rays of high energy. Some of these objects are able to confine fermions which consequently become massless in the core of the object \cite{witten}, \cite{vorton3}. These fermions travel at light speed in the core and may generate a large current without dissipation. This raises interest about the generation mechanisms for these currents inside the defect. This question is analyzed here by studying the inverse photoelectric effect for these objects namely, the absorption of a fermion with the consequent emission of a photon or a massive boson by the extended defect. Another motivation for the present work is that there exists a discussion in condensed matter about the role of the bound spectrum in the macroscopic Magnus force that the vortex experiences in certain type of superfluids or superconductors. The discussion is about wether the main force comes from scattering of these fermions by the object or by the effect of the environment on the bound states in the object, which may induce a spectral flow leading to an effective macroscopic force \cite{pelea1}, \cite{pelea2}, \cite{pelea3}. Without claiming that the results described here are conclusive in the context of condensed matter, this work presents a comparison between these two effects for vortons interacting with a plasma of fermions.
