Abstract

<p>The ground states of ideal one-dimensional frustrated magnets including singlet dimer, Haldane dimer, vector chiral, spin density wave, and bond Nematic states are reviewed and compared with the states realized in realistic model compounds. In the ferromagnetic frustrated chain LiCuVO4 the observed spiral spin structure in zero field is ascribed to the classical analogue of the vector chiral state. Meanwhile the spin density wave at high field is purely quantum state induced by geometrical frustration and the nesting of spinon Fermi surface.</p>
