本工作的主要重点是使用“变形QCD”作为玩具模型，以理论上可控的方式测试与斜约束有关的想法。我们明确地表明，弱耦合规范理论中的斜约束是由相位布洛赫型结构位移的单极子类型的凝聚而产生的。它应该与传统的和普遍接受的观点形成对比，即约束是由于带电双子的凝结，而带电双子确实是由于威滕效应而在系统中出现的。我们解释了“dyon”机制没有实现的基本原因——这是因为威腾效应适用于作为外部源的静态磁单极子。当单极子类型不是静态的，而是动态的自由度时，它应该与我们的情况形成对比，动态自由度的波动决定了系统的基态。
The main focus of this work is to test the ideas related to the oblique confinement in a theoretically controllable manner using the “deformed QCD” as a toy model. We explicitly show that the oblique confinement in the weakly coupled gauge theories emerges as a result of condensation oftypes of monopoles shifted by the phasein Bloch type construction. It should be contrasted with the conventional and commonly accepted viewpoint that the confinement atis due to the condensation of the electrically charged dyons which indeed normally emerge in the systems withas a result of Witten’s effect. We explain the basic reason why the “dyon” mechanism does not materialize—it is because the Witten’s effect holds for a static magnetic monopole treated as an external source. It should be contrasted with our case when-types of monopoles are not static, but rather the dynamical degrees of freedom which fluctuate and themselves determine the ground state of the system.
