Description:
Author(s): Cheng-Chien Chen, Lukas Muechler, Roberto Car, Titus Neupert, and Joseph Maciejko We study the two-dimensional (2D) Hubbard model using exact diagonalization for spin- 1 / 2 fermions on the triangular and honeycomb lattices decorated with a single hexagon per site. In certain parameter ranges, the Hubbard model maps to a quantum compass model on those lattices. On the triangular lat… [Phys. Rev. Lett. 117, 096405] Published Thu Aug 25, 2016
