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…
