Charge Stripe in an Antiferromagnet: 1d Band of Composite Excitations
A. L. Chernyshev, Steven R. White, A. H. Castro Neto
With the help of analytical and numerical studies of the - model we argue that the charge stripe in an antiferromagnetic insulator should be understood as a system of holon…
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…
