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…

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…

Realizing attractive interacting topological surface fermions: A resonating TI- thin film hybrid platform
Saran Vijayan, Fei Zhou
In this article, we propose a practical way to realize topological surface Dirac fermions with tunable attractive interaction between them. The approach involves coating the surfac…
