Proliferation Transitions for Non-Abelian Anyons
Sakura Schafer-Nameki, Yunqin Zheng, Andrea Antinucci
We construct phase transitions that proliferate condensable anyons in general 2+1d topological orders, including non-abelian ones. The central tool that provides a systematic appro…
Intrinsically/Purely Gapless-SPT from Non-Invertible Duality Transformations
Linhao Li, Masaki Oshikawa, Yunqin Zheng
The Kennedy-Tasaki (KT) transformation was used to construct the gapped symmetry protected topological (SPT) phase from the symmetry breaking phase with open boundary condition, an…
Subsystem Non-Invertible Symmetry Operators and Defects
Weiguang Cao, Linhao Li, Masahito Yamazaki +1
We explore non-invertible symmetries in two-dimensional lattice models with subsystem symmetry. We introduce a subsystem -gauging procedure, called the s…
Non-Invertible Duality Transformation Between SPT and SSB Phases
Linhao Li, Masaki Oshikawa, Yunqin Zheng
In 1992, Kennedy and Tasaki constructed a non-local unitary transformation that maps between a spontaneously symmetry breaking phase and the Halda…
Boson-fermion duality with subsystem symmetry
Weiguang Cao, Masahito Yamazaki, Yunqin Zheng
We explore an exact duality in d between the fermionization of a bosonic theory with a subsystem symmetry and a fermionic theory with a subsyst…
Decorated Defect Construction of Gapless-SPT States
Linhao Li, Masaki Oshikawa, Yunqin Zheng
Symmetry protected topological (SPT) phases are one of the simplest, yet nontrivial, gapped systems that go beyond the Landau paradigm. In this work, we study an extension of the n…
Gauge Enhanced Quantum Criticality and Time Reversal Domain Wall: SU(2) Yang-Mills Dynamics with Topological Terms
Juven Wang, Yi-Zhuang You, Yunqin Zheng
We explore the low energy dynamics of the four siblings of Lorentz symmetry enriched SU(2) Yang-Mills theory with a theta term at in d. Due to a mixed anomaly between…
Multi-Layer Restricted Boltzmann Machine Representation of 1D Quantum Many-Body Wave Functions
Huan He, Yunqin Zheng, B. Andrei Bernevig +1
We consider representing two classes of 1D quantum wave functions of spin systems, including the AKLT and CFT correlator wave functions, in terms of multi-layer restricted Boltzman…
Restricted Boltzmann Machines and Matrix Product States of 1D Translational Invariant Stabilizer Codes
Yunqin Zheng, Huan He, Nicolas Regnault +1
We discuss the relations between restricted Boltzmann machine (RBM) states and the matrix product states (MPS) for the ground states of 1D translational invariant stabilizer codes.…
Tunneling Topological Vacua via Extended Operators: (Spin-)TQFT Spectra and Boundary Deconfinement in Various Dimensions
Juven Wang, Kantaro Ohmori, Pavel Putrov +6
Distinct quantum vacua of topologically ordered states can be tunneled into each other via extended operators. The possible applications include condensed matter and quantum cosmol…
Entanglement entropy of (3+1)D topological orders with excitations
Xueda Wen, Huan He, Apoorv Tiwari +2
Excitations in (3+1)D topologically ordered phases have very rich structures. (3+1)D topological phases support both point-like and string-like excitations, and in particular the l…
Entanglement Entropy From Tensor Network States for Stabilizer Codes
Huan He, Yunqin Zheng, B. Andrei Bernevig +1
In this paper, we present the construction of tensor network states (TNS) for some of the degenerate ground states of 3D stabilizer codes. We then use the TNS formalism to obtain t…
Structure of the Entanglement Entropy of (3+1)D Gapped Phases of Matter
Yunqin Zheng, Huan He, Barry Bradlyn +3
We study the entanglement entropy of gapped phases of matter in three spatial dimensions. We focus in particular on size-independent contributions to the entropy across entanglemen…
Field Theories for Gauged Symmetry Protected Topological Phases: Abelian Gauge Theories with non-Abelian Quasiparticles
Huan He, Yunqin Zheng, Curt von Keyserlingk
Dijkgraaf-Witten (DW) theories are of recent interest to the condensed matter community, in part because they represent topological phases of matter, but also because they characte…
Quantum Spin Hall Effect as Global Gauge Anomaly
Yunqin Zheng, Shaolong Wan
We study the relation between the quantum spin Hall effect(QSHE) and the global gauge anomaly and discover that there exists an one-to-one correspondence between the…
