Universal Design and Physical Applications of Non-Uniform Cellular Automata on Translationally Invariant Lattices
Xiang-You Huang, Jie-Yu Zhang, Peng Ye
Motivated by recent theoretical and experimental advances, hyperbolic lattices have emerged as a paradigmatic setting in which geometry becomes an active organizing principle of qu…
Fracton Topological Holography
Yu-Tao Hu, Jie-Yu Zhang, Peng Ye
Topological holography (TH), or SymTFT, realizes symmetries and dualities of a quantum system as boundary data of a topological bulk in one higher dimension. We formulate fracton t…
Spurious Strange Correlators in Symmetry-Protected Topological Phases
Wei-Liang Gao, Jie-Yu Zhang, Zheng-Xin Liu +1
Strange correlator is a powerful tool widely used in detecting symmetry-protected topological (SPT) phases. However, the result of strange correlator crucially relies on the adopti…
Fusion Rules of Mobility
Jie-Yu Zhang, Peng Ye
In topological phases of matter, fusion rules dictate how anyonic topological charges combine. However, the transformation of quasiparticle mobility under fusion remains largely un…
Higher-Order Cellular Automata Generated Symmetry-Protected Topological Phases and Detection Through Multi-Point Strange Correlators
Jie-Yu Zhang, Meng-Yuan Li, Peng Ye
In computer and system sciences, higher-order cellular automata (HOCA) are a type of cellular automata that evolve over multiple time steps and generate complex patterns, which hav…
