Controlled hole doping of a Mott insulator of ultracold fermionic atoms
arXiv:1001.1918 · doi:10.1103/PhysRevA.82.011606
Abstract
Considering a system of ultracold atoms in an optical lattice, we propose a simple and robust implementation of a quantum simulator for the homogeneous t-J model with a well-controlled fraction of holes x. The proposed experiment can provide valuable insight into the physics of cuprate superconductors. A similar scheme applied to bosons, moreover, allows one to investigate experimentally the subtle role of inhomogeneity when a system passes from one quantum phase to another.
