Topological phases and quantum criticality from Chern-Simons-matter theories
Yunchao Hao, Yingcheng Li, Kangle Li +1
Motivated by recent numerical studies where various Chern-Simons-matter theories emerge, we analytically study topological phases and quantum criticality in two-dimensional…
Microscopic universal theory of symmetry-enriched topological quantum spin liquids
Yingcheng Li, Liujun Zou
An ultimate theory of a phase of matter should describe all its universal properties via quantities that are measurable numerically and experimentally. In this work, we present a m…
Non-Abelian Particle-Loop, Fracton, and Planon Condensation in Cage-Net Models
Yifei Wang, Yu Zhao, Yingcheng Li +2
We present a framework for non-Abelian p-loop, fracton, and planon condensation in 3+1 dimensions by constructing extended cage-net fracton models using decoupled layers of the Hu-…
Characterizing the ambiguity in topological entanglement entropy
Yingcheng Li
Topological entanglement entropy (TEE), the sub-leading term in the entanglement entropy of topological order, is the direct evidence of the long-range entanglement. While effectiv…
Experimental realization of a topologically protected Hadamard gate via braiding Fibonacci anyons
Yu-ang Fan, Yingcheng Li, Yuting Hu +9
Topological quantum computation (TQC) is one of the most striking architectures that can realize fault-tolerant quantum computers. In TQC, the logical space and the quantum gates a…
Dynamical-Invariant-based Holonomic Quantum Gates: Theory and Experiment
Yingcheng Li, Tao Xin, Chudan Qiu +5
Among existing approaches to holonomic quantum computing, the adiabatic holonomic quantum gates (HQGs) suffer errors due to decoherence, while the non-adiabatic HQGs either require…
Electric-magnetic duality in the quantum double models of topological orders with gapped boundaries
Hongyu Wang, Yingcheng Li, Yuting Hu +1
We generalize the Electric-magnetic (EM) duality in the quantum double (QD) models to the case of topological orders with gapped boundaries. We also map the QD models with boundari…
Anyon exclusions statistics on surfaces with gapped boundaries
Yingcheng Li, Hongyu Wang, Yuting Hu +1
An anyon exclusion statistics, which generalizes the Bose-Einstein and Fermi-Dirac statistics of bosons and fermions, was proposed by Haldane[1]. The relevant past studies had cons…
Gapped Boundary Theory of the Twisted Gauge Theory Model of Three-Dimensional Topological Orders
Hongyu Wang, Yingcheng Li, Yuting Hu +1
We extend the twisted gauge theory model of topological orders in three spatial dimensions to the case where the three spaces have two dimensional boundaries. We achieve this by sy…
Entanglement Entropy of Topological Orders with Boundaries
Chaoyi Chen, Ling-Yan Hung, Yingcheng Li +1
In this paper we explore how non trivial boundary conditions could influence the entanglement entropy in a topological order in 2+1 dimensions. Specifically we consider the special…
