Antiferromagnetic systems with spin gap: exact results
نویسنده
چکیده
We describe some antiferromagnetic systems which exhibit spin gaps. We also discuss the effect of doping one such system, namely, the spin-ladders, with holes. Some model antiferromagnetic systems with spin gap are reviewed for which exact results are available. Exact results for a doped spin-ladder model are also mentioned.

Excitation Spectrum of One-Dimensional Spin-1 Antiferromagnetic Heisenberg Chain: Green's Function Approach
The one-dimensional spin-1 Heisenberg antiferromagnetic chain is studied by a Green's function technique. The excitation spectrum is obtained. The dispersion of excitations for an infinite isotropic chain is numerically calculated. At k 0 we obtain a gap 2D which is equal to 0:826J and at k p we obtain D 0:41J, which is in very good agreement with the exact numerical results of White and ...
متن کاملValence bond mapping of antiferromagnetic spin chains
Antiferromagnetic spin chains have been the subject of intense interest in recent years, largely due to the conjecture by Haldane that chains built from integer spins should exhibit a gap in their energy spectrum. The existence of this gap, originally predicted on the basis of simple fieldtheoretic considerations, was subsequently confirmed experimentally. Much insight into the properties of an...

The density matrix renormalization group method is generalized to one dimensional random systems. Using this method, the energy gap distribution of the spin-1/2 random antiferromagnetic Heisenberg chain is calculated. The results are consistent with the predictions of the renormalization group theory demonstrating the effectiveness of the present method in random systems. The possible applicati...
متن کاملPseudogap Induced Antiferromagnetic Spin Correlation in High-Temperature Superconductors
The pseudogap phenomena observed on cuprate high temperature superconductors are investigated based on the exact diagonalization method on the finite cluster t-J model. The results show the presence of the gap-like behavior in the temperature dependence of various magnetic properties; the NMR relaxation rate, the neutron scattering intensity and the static susceptibility. The calculated spin co...
متن کاملDynamics of Coupled Quantum Spin Chains.
Static and dynamical properties of weakly coupled antiferromagnetic spin chains are treated using a mean–field approximation for the interchain coupling and exact results for the resulting effective one–dimensional problem. Results for staggered magnetization, Néel temperature and spin wave excitations are in agreement with experiments on KCuF3. The existence of a narrow longitudinal mode is pr...
