Peeling off Abelian Anyons and Proliferation Transitions

Meng Cheng, Nathan Seiberg

We study the invertible one-form global symmetry of a (2+1)-dimensional topological quantum field theory (TQFT). A universal description of this symmetry ``peels off'' all the Abel…

Note on proliferation transitions of non-Abelian anyons

Meng Cheng

We study phase transitions out of a (2+1)d topological phase driven by the proliferation of anyons in a braided fusion subcategory. We describe a general theoretical framework for…

Lieb-Schultz-Mattis Anomalies and Anomaly Matching

Liujun Zou, Meng Cheng

Lieb-Schultz-Mattis (LSM) anomalies are powerful symmetry-based constraints on the correlation, entanglement and dynamics of quantum many-body systems. In this review, we discuss v…

Proliferation transitions from a topological phase in dimensions

Meng Cheng, Nathan Seiberg

We consider phase transitions out of a general topological phase in dimensions. We assume that the transition is triggered by a single Abelian anyon, which becomes light near…

Finite-temperature quantum topological order in three dimensions

Shu-Tong Zhou, Meng Cheng, Tibor Rakovszky +2

We identify a three-dimensional system that exhibits long-range entanglement at sufficiently small but nonzero temperature--it therefore constitutes a quantum topological order at…

Topological stabilizer models on continuous variables

Julio C. Magdalena de la Fuente, Tyler D. Ellison, Meng Cheng +1

We construct a family of two-dimensional topological stabilizer codes on continuous variable (CV) degrees of freedom, which generalize homological rotor codes and the toric-GKP cod…

Chiral spin liquid in a generalized Kitaev honeycomb model with 1-form symmetry

Yu-Xin Yang, Meng Cheng, Ji-Yao Chen

We explore a large generalization of the Kitaev model on the honeycomb lattice with a simple nearest-neighbor interacting Hamiltonian. In particular, we focus on the $\mathbb{Z…

Towards a classification of mixed-state topological orders in two dimensions

Tyler Ellison, Meng Cheng

The classification and characterization of topological phases of matter is well understood for ground states of gapped Hamiltonians that are well isolated from the environment. How…
