相对论自发崩溃产生的QCD
QCD emergent from spontaneous breakdown of relativity
摘要：
真空相对论不变性的自发破坏可以从包含费米子的U（1）Higgs模型导出量子色动力学，如果突现理论是洛伦兹不变性的。在这个模型中，真空变得各向异性，并且在自旋为1的真空的三重态上产生的费米子获得类似于颜色自由度的简并性。源于转动对称性破缺的Nambu-Goldstone玻色子为准费米子提供了SU（3）$\times$ U（1）有效相互作用，这种相互作用可以解释为胶子和光子的中介作用。准夸克的禁闭以及南部-戈德斯通胶子的禁闭都来自突现理论的洛伦兹不变性。
英文摘要：
Spontaneous violation of relativistic invariance of the vacuum can derive quantum chromodynamics from an U(1) Higgs model including fermions, if the emergent theory is Lorentz invariant. In this model, the vacuum becomes anisotropic, and a fermion created on a triplet of spin-one vacua acquires degeneracy analogous to the color degrees of freedom. The Nambu-Goldstone bosons originating from the breakdown of rotational symmetry provide the quasi fermions with SU(3)$\times$U(1) effective interactions, which are interpretable as mediated by gluons and photons. The confinement of quasi quarks as well as that of Nambu-Goldstone gluons follow from the Lorentz invariance of the emergent theory.
