论文摘要
我们考虑强烈相互作用的二维dirac费尔米式的自发对称性破坏过渡，最小化与质量和新兴仪表阶阶参数。使用重新归一化的组分析，我们表明量规场的存在导致新型费米昂诱导的量子（多）临界性，其中违反了假定的新兴洛伦兹不变性。我们以蜂窝晶格上的电荷密度波顺序引起的翻译对称性破坏的示例来说明这一点。最后，我们确定拓扑相变是通过这种有效的现场理论很好地描述的。
We consider spontaneous symmetry breaking transitions of strongly interacting two-dimensional Dirac fermions minimally coupled to mass and emergent gauge field order parameters. Using a renormalization group analysis, we show that the presence of gauge fields leads to novel fermion induced quantum (multi-)criticality where the putative emergent Lorentz invariance is violated. We illustrate this with the example of translational symmetry breaking due to charge-density wave order on the honeycomb lattice. Finally, we identify that topological phase transitions are well described by this effective field theory.
