Kosterlitz--Thouless Criticality in a Dipole-Conserving XY Model
Han-Xie Wang, Shuai A. Chen, Zheng Yan +1
In this Letter, we study finite-temperature phase transitions in a two-dimensional classical statistical model called ``dipole-conserving XY model''. Unlike the conventional XY mod…

Non-invertible symmetries and mixed anomalies from equations of motion in (3+1)D twisted topological quantum field theories
Zhi-Feng Zhang, Yizhou Huang, Qing-Rui Wang +1
We develop a systematic study on the topological operators that generate invertible and non-invertible higher-form symmetries in twisted topological quantu…
