论文摘要
超冷的一阶相变是典型的理论，其中共形对称性主要是自发断裂的。在这些理论中，平面标量方向的命运对显式断裂变形的大小和缩放维度高度敏感。对于给定的变形，耦合必须位于特定区域以实现超冷的一阶相变。我们确定弱耦合理论中的超冷窗口，并获得对其边界的完全分析理解。映射这些边界使我们能够识别扩大超冷窗口的变形并分析其动态。为了完整性，我们还使用全息双重偶尔讨论了共耦合的保形场理论，其中超冷窗口的完整表征受到计算性问题的挑战。
Supercooled first order phase transitions are typical of theories where conformal symmetry is predominantly spontaneously broken. In these theories the fate of the flat scalar direction is highly sensitive to the size and the scaling dimension of the explicit breaking deformations. For a given deformation, the coupling must lie in a particular region to realize a supercooled first order phase transition. We identify the supercooling window in weakly coupled theories and derive a fully analytical understanding of its boundaries. Mapping these boundaries allows us to identify the deformations enlarging the supercooling window and to characterize their dynamics analytically. For completeness we also discuss strongly coupled conformal field theories with an holographic dual, where the complete characterization of the supercooling window is challenged by calculability issues.
