Effect of impurities on quasi-2D quantum antiferromagnet
A. L. Chernyshev, Y. C. Chen, A. H. Castro Neto
We have studied the static and dynamic properties of quasi-two-dimensional quantum antiferromagnets (AF) diluted with spinless impurities using spin-wave theory and -matrix appr…

Diluted quantum antiferromagnets: spin excitations and long-range order
A. L. Chernyshev, Y. C. Chen, A. H. Castro Neto
We have studied the static and dynamic magnetic properties of two-dimensional (2D) and quasi-two-dimensional, spin-S, quantum Heisenberg antiferromagnets (QHAF) diluted with spinle…

Effective Field Theory for Layered Quantum Antiferromagnets with Non-Magnetic Impurities
Y. C. Chen, A. H. Castro Neto
We propose an effective two-dimensional quantum non-linear sigma model combined with classical percolation theory to study the magnetic properties of site diluted layered quantum a…
