论文摘要
我们研究了较高维度的仪表理论的动态自定位。具体而言，我们考虑了线性dilaton（发条）背景中的5D $ u（1）$量规理论，沿横向（第五）方向和纵向（四维）方向具有各向异性量规耦合。通过使用晶格技术，我们计算空间斑块和螺旋模量，并确定模型的相图。我们发现该模型表现出一个新的阶段，一个层阶段，其中四维物理学从五维动力学中脱离了新相位。层相对应于沿第五方向的强力，沿着四维纵向方向进行库仑相。这与发条机理一致，在没有基本的小参数的理论中产生具有指数抑制相互作用的光颗粒。
We study dynamical self-localization of gauge theories in higher dimensions. Specifically, we consider a 5D $U(1)$ gauge theory in the linear dilaton (clockwork) background, with anisotropic gauge couplings along the transverse (fifth) direction and the longitudinal (four-dimensional) directions. By using lattice techniques, we calculate the space plaquettes and the helicity moduli and we determine the phase diagram of the model. We find strong evidence that the model exhibits a new phase, a layer phase, where the four-dimensional physics decouples from the five-dimensional dynamics. The layer phase corresponds to a strong force along the fifth direction and a Coulomb phase along the four-dimensional longitudinal directions. This is in accordance with the clockwork mechanism where light particles with exponentially suppressed interactions are generated in theories with no fundamental small parameters.
