Equivalence class of Emergent Single Weyl fermion lattice models in 3 dimensions: gapless superconductors and superfluids versus chiral fermions
Gabriel Meyniel, Fei Zhou
In this article, we put forward a practical but generic approach towards constructing a large family of dimension lattice models which can naturally lead to a single Weyl c…
Topologically shadowed quantum criticality: A non-compact conformal manifold
Tianyao Fang, Weicheng Ye, Zhengcheng Gu +1
We put forward a proposal for topological quantum critical points (tQCPs) separating non-invertible chiral topological orders in dimensions. We conjecture that these tQCPs…
Surface Topological Quantum Criticality II: Conformal manifolds, Isolated fixed points and Entanglement
Saran Vijayan, Fei Zhou
In this article, we propose the realization of conformal manifolds, which are smooth manifolds of scale-conformal invariant interacting Hamiltonians in two-dimensional quantum many…
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…
Surface topological quantum criticality: Conformal manifolds and Discrete Strong Coupling Fixed Points
Saran Vijayan, Fei Zhou
In this article, we study quantum critical phenomena in surfaces of symmetry-protected topological matter, i.e. surface topological quantum criticality. A generic phase boundary of…
