Systematic Low-Energy Effective Field Theory for Magnons and Holes in an Antiferromagnet on the Honeycomb Lattice
F. Kämpfer, B. Bessire, M. Wirz +3
Based on a symmetry analysis of the microscopic Hubbard and t-J models, a systematic low-energy effective field theory is constructed for hole-doped antiferromagnets on the honeyco…

Microscopic Model versus Systematic Low-Energy Effective Field Theory for a Doped Quantum Ferromagnet
U. Gerber, C. P. Hofmann, F. Kampfer +1
We consider a microscopic model for a doped quantum ferromagnet as a test case for the systematic low-energy effective field theory for magnons and holes, which is constructed in c…

Loop-Cluster Simulation of the - Model on the Honeycomb Lattice
F. -J. Jiang, F. Kämpfer, M. Nyfeler +1
Inspired by the lattice structure of the unhydrated variant of the superconducting material NaCoOyHO at , we study the - model on a honeycomb la…
