Essay

Objects of the research: spin-1/2 antiferromagnetic Heisenberg model on several frustrated lattices. The goal is to develop a systematic theory for frustrated quantum Heisenberg antiferromagnets. Methods: a perturbation theory and numerical methods . Theoretical and practical results: an effective Hamiltonians and interpretation of experiments for several magnetic compounds. Novelty: for frustrated quantum Heisenberg antiferromagnets in high magnetic fields and low temperatures an effective models have been constructed at the first time. Implementation is planed. The region of application: condensed matter physics.
