An extended Hubbard model with ring exchange: a route to a non-Abelian topological phase
Michael Freedman, Chetan Nayak, Kirill Shtengel
We propose an extended Hubbard model on a 2D Kagome lattice with an additional ring-exchange term. The particles can be either bosons or spinless fermions . At a special filling fr…

Non-Abelian topological phases in an extended Hubbard model
Michael Freedman, Chetan Nayak, Kirill Shtengel
We describe four closely related Hubbard-like models (models A, B, C and D) of particles that can hop on a 2D Kagome lattice interacting via Coulomb repulsion. The particles can be…
