由于修正Villain离散化提供了精确整数拓扑量,它为在有限格距下获得正确反常结构提供了一条途径。我将展示一个四维纯玻色子修正Villain模型,该模型具有ABJ型矢量-矢量-轴矢量反常。该模型可能从一个自发对称性破缺相到另一个相发生直接连续相变,这为获得具有VVA反常的四维共形场论带来了希望。
英文摘要
Because it offers exactly-integer topological quantities, the modified Villain discretization offers a route to correct anomaly structure at finite lattice spacing. I will present a 4-dimensional purely-bosonic modified Villain model with an ABJ-type vector-vector-axial anomaly. The model may have a direct continuous phase transition from one SSB phase to another, giving hope of yielding 4D CFT with a VVA anomaly.
