QUANTUM PHASES IN TWO-DIMENSIONAL FRUSTRATED SPIN-1/2 ANTIFERROMAGNETS
Philippe Sindzingre, C. Lhuillier, J.-B. Fouet
We describe four phases found in two-dimensional quantum antiferromagnets. Two of them display long range order at T=0: the Néel state and the Valence Bond Crystal. The last two are Spin-Liquids. Properties of these different states are shortly described and likely conditions of their occurence outlined.
