Non-Invertible Gauss Law and Axions
Yichul Choi, Ho Tat Lam, Shu-Heng Shao
In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries. Since the G…
Gapped Lineon and Fracton Models on Graphs
Pranay Gorantla, Ho Tat Lam, Nathan Seiberg +1
We introduce a stabilizer code that can be defined on any spatial lattice of the form , where is a general graph. We also present the low-energy…
Gapless Infinite-component Chern-Simons-Maxwell Theories
Xie Chen, Ho Tat Lam, Xiuqi Ma
The infinite-component Chern-Simons-Maxwell (iCSM) theory is a 3+1D generalization of the 2+1D Chern-Simons-Maxwell theory by including an infinite number of coupled gauge fields.…
2+1d Compact Lifshitz Theory, Tensor Gauge Theory, and Fractons
Pranay Gorantla, Ho Tat Lam, Nathan Seiberg +1
The 2+1d continuum Lifshitz theory of a free compact scalar field plays a prominent role in a variety of quantum systems in condensed matter physics and high energy physics. It is…
Non-invertible Time-reversal Symmetry
Yichul Choi, Ho Tat Lam, Shu-Heng Shao
In gauge theory, it is commonly stated that time-reversal symmetry only exists at or for a -periodic -angle. In this paper, we point out that in both the free Maxw…
Fractons on Graphs and Complexity
Pranay Gorantla, Ho Tat Lam, Shu-Heng Shao
We introduce two exotic lattice models on a general spatial graph. The first one is a matter theory of a compact Lifshitz scalar field, while the second one is a certain rank-2 $U(…
