Algebraic Tensor Network Renormalization and Holographic duality
Chenqi Meng, Tian Lan, Zhengcheng Gu
Emergent generalized symmetries and the holographic principle play very important roles in understanding quantum phase transitions. In recent years, tensor-network renormalization…
Topologically shadowed quantum criticality: A non-compact conformal manifold
Tianyao Fang, Weicheng Ye, Zhengcheng Gu +1
We propose a family of topological quantum critical points (tQCPs) separating non-invertible chiral topological orders in dimensions. We conjecture that these tQCPs can be…
Classification of Interacting Topological Crystalline Superconductors in Three Dimensions and Beyond
Shang-Qiang Ning, Xing-Yu Ren, Qing-Rui Wang +2
Although classification for free-fermion topological superconductors (TSC) is established, systematically understanding the classification of 3D interacting TSCs remains difficult,…
Parity violation as enforced symmetry breaking in 3D fermionic topological order
Shang-Qiang Ning, Yang Qi, Chenjie Wang +1
Symmetry can be intrinsically broken in topological phases due to inherent incompatibilities, a phenomenon known as enforced symmetry breaking (ESB) in the framework of topological…
Dynamic critical exponents as an emergent property at interacting topological quantum critical points
Fan Yang, Zheng-Cheng Gu, Fei Zhou
In standard studies of quantum critical points (QCPs), the dynamic critical exponent is introduced as a fundamental parameter along with global symmetries to identify universal…
Accurate Simulation of the Hubbard Model with Finite Fermionic Projected Entangled Pair States
Wen-Yuan Liu, Huanchen Zhai, Ruojing Peng +2
We demonstrate the use of finite-size fermionic projected entangled pair states, in conjunction with variational Monte Carlo, to perform accurate simulations of the ground-state of…
Non-invertible SPTs: an on-site realization of (1+1)d anomaly-free fusion category symmetry
Chenqi Meng, Xinping Yang, Tian Lan +1
We investigate (1+1)d symmetry-protected topological (SPT) phases with fusion category symmetries. We emphasize that the UV description of an anomaly-free fusion category symmetry…
The emergence of Einstein gravity from topological supergravity in D
Tianyao Fang, Zheng-Cheng Gu
The topological aspects of Einstein gravity suggest that topological invariance could be a more profound principle in understanding quantum gravity. In this work, we explore a topo…
Stacking Group Structure of Fermionic Symmetry-Protected Topological Phases
Xing-Yu Ren, Shang-Qiang Ning, Yang Qi +2
In the past decade, there has been a systematic investigation of symmetry-protected topological (SPT) phases in interacting fermion systems. Specifically, by utilizing the concept…
Exactly solvable models for U(1) symmetry-enriched topological phases
Qing-Rui Wang, Meng Cheng
We propose a general construction of commuting projector lattice models for 2D and 3D topological phases enriched by U(1) symmetry, with finite-dimensional Hilbert space per site.…
Computing classification of interacting fermionic symmetry-protected topological phases using topological invariants
Yunqing Ouyang, Qing-Rui Wang, Zheng-Cheng Gu +1
In recent years, great success has been achieved on the classification of symmetry-protected topological (SPT) phases for interacting fermion systems by using generalized cohomolog…
Exactly Solvable Models for Symmetry-Enriched Topological Phases
Meng Cheng, Zheng-Cheng Gu, Shenghan Jiang +1
We construct fixed-point wave functions and exactly solvable commuting-projector Hamiltonians for a large class of bosonic symmetry-enriched topological (SET) phases, based on the…
