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…
Chiral symmetry breaking and topological charge of graphene nanoribbons
Hyun Cheol Lee, S. -R. Eric Yang
We explore the edge properties of rectangular graphene nanoribbons featuring two zigzag edges and two armchair edges. Although the self-consistent Hartree-Fock fields break chiral…
Bosonization Theory of Excitons in One-dimensional Narrow Gap Semiconductors
H. C. Lee, S. -R. Eric Yang
Excitons in one-dimensional narrow gap semiconductors of anti-crossing quantum Hall edge states are investigated using a bosonization method. The excitonic states are studied by ma…
Anomalous tunneling conductances of a spin singlet ν=2/3 edge states: Interplay of Zeeman splitting and Long Range Coulomb Interaction
H. C. Lee
The point contact tunneling conductance between edges of the spin singlet quantum Hall states is studied both in the quasiparticle tunneling picture and in…
Spin-charge separation in Quantum Hall Liquids
H. C. Lee, S. -R. Eric Yang
We have investigated chiral edges of a quantum Hall(QH) liquid at filling factor ν=2. We find that spin and charge separate in the presence of the long-range Coulomb interaction, a…
