Symmetry-breaking line defects embedded to a 3D critical bulk
Shuai Yang, Liang-dong Hu, Yan Chen +1
While spontaneous breaking of a discrete symmetry in one-dimensional classical systems with short-range interactions is absent, it is expected that a line defect embedded in a bulk…
Conformal Nature of Quantum Phase Transitions via Fuzzy Three-Sphere Regularization
Xue Meng, Liangdong Hu, Wei Zhu
Conformal field theory (CFT) offers a modern viewpoint for understanding phase transitions. However, directly accessing the conformal algebra and microscopically uncovering the eme…
