Quantum Antiferromagnet

Within the Schwinger-boson approach for the t-J model, the single hole problem in a two-dimensional quantum antiferromagnet is studied by using the quantum Bogoliubovde Gennes formalism which treats the distortion of the spin background and quantum spin fluctuations on an equal footing. Several self-trapped localized hole states are found in the distorted spin-background as in the case of an anisotropic Heisenberg model. These localized hole states survive at finite temperatures when the antiferromagnetic order becomes short-ranged. The energy separation between the two lowest states is reduced by considering the spin-background distortion, but it remains finite.

The antiferromagnetism of the two-dimensional Hubbard model is investigated analytically and numerically in the vicinity of half-filling. It is found that for a small but finite concentration of holes a regularly spaced array of domain walls is formed, with the holes localized at the domain walls, i.e. one has an insulating incommensurate antifer romagnet, with a linearly polarized magnetisation pattern and a modulation wavevector proportional to the hole concentration. Above a critical concentration of holes, pockets of free carriers appear, coexisting with incommensurate antiferromagnetic order. Only at even higher hole concentration does the antiferromagnetism vanish completely. Based on a Landau expansion, the different possible antiferromagnetic states are discussed.
