Quantum Entanglement of Anyonic Charges and Emergent Spacetime Geometry
Hoang-Anh Le, Hyun Cheol Lee, S. -R. Eric Yang
Intrinsically topologically ordered phases can host anyons. Here, we take the view that entanglement between anyons can give rise to an emergent geometry resembling Anti-de Sitter…
Instantons and topological order in two-leg electron ladders: A universality class
S. -R. Eric Yang, Hyun Cheol Lee, Hoang-Anh Le +1
Our numerical study of the disordered Hubbard model with nearest-neighbor hopping shows that a two-leg electron ladder has a finite topological entanglement entropy in the regime w…
Anomalous Induced Density of Supercritical Coulomb Impurities in Graphene Under Strong Magnetic Fields
Hoang-Anh Le, S. -R. Eric Yang
The Coulomb impurity problem of graphene, in the absence of a magnetic field, displays discrete scale invariance. Applying a magnetic field introduces a new magnetic length scale $…
Mutual information and correlations across topological phase transitions in topologically ordered graphene zigzag nanoribbons
In-Hwan Lee, Hoang-Anh Le, S. -R. Eric Yang
Graphene zigzag nanoribbons, initially in a topologically ordered state, undergo a topological phase transition into crossover phases distinguished by quasi-topological order. We c…
Phase Diagram and Crossover Phases of Topologically Ordered Graphene Zigzag Nanoribbons: Role of Localization Effects
Hoang Anh Le, In Hwan Lee, Young Heon Kim +1
We computed the phase diagram of the zigzag graphene nanoribbons as a function of on-site repulsion, doping, and disorder strength. The topologically ordered phase undergoes topolo…
