D=3维带电标量的凝聚

On condensation of charged scalars in D=3 dimensions

Patricio Gaete, José A. Helaÿel-Neto

摘要:

通过使用规范不变的,但路径相关的变量形式主义,我们研究了凝聚的物理观测量的三维希格斯模型的影响。结果,对于像$m_H^2 ϕ^ * ϕ$这样的物理质量项的情况,我们恢复了筛选势。有趣的是,在质量项$- m_H^2 ϕ^ * ϕ$为“错号”的情况下,发现了一些意想不到的特征,即相互作用能是有效贝塞尔势和线性势之和,从而导致静电荷的禁闭.然而,当包含陈-西蒙斯项时,令人惊讶的结果是该理论描述了一个精确的筛选阶段。

英文摘要:

By using the gauge-invariant, but path-dependent, variables formalism, we study the impact of condensates on physical observables for a three-dimensional Higgs-like model. As a result, for the case of a physical mass term like $m_H^2 ϕ^ * ϕ$, we recover a screening potential. Interestingly enough, in the case of a "wrong-sign" mass term $- m_H^2 ϕ^ * ϕ$, unexpected features are found. It is shown that the interaction energy is the sum of an effective-Bessel and a linear potential, leading to the confinement of static charges. However, when a Chern-Simons term is included, the surprising result is that the theory describes an exactly screening phase.
