Spin-Peierls and spin-Hquid phases of Kagomb quantum antiferromagnets
The ground state of the spin-i nearest-neighbor Heisenberg quantum antiferromagnet on the KagomC lattice probably lacks &in order; therefore, conventional spin-wave analysis breaks down. To ascertain the ground state, we instead use a systematic l/n expansion with .SU(n) fermions. Two distinct states occur in the large-n limit, depending on the size of the biquadratic interaction z When ?=O, th...
متن کاملSpin-Peierls States of Quantum Antiferromagnets on the CaV4O9 Lattice.
We discuss the quantum paramagnetic phases of Heisenberg antiferromagnets on the 1/5-depleted square lattice found in CaV4O9. The possible phases of the quantum dimer model on this lattice are obtained by a mapping to a quantum-mechanical height model. In addition to the “decoupled” phases found earlier, we find a possible intermediate spin-Peierls phase with spontaneously-broken lattice symmet...
متن کاملSoliton Energetics in Peierls-Hubbard Models
We study the effect of electron-electron correlations on the energetics of solitons in electron-phonon models of quasi one-dimensional materials, In these combined PeierlsHubbard models, by use of quantum Monte Carlo techniques, we (l) establish that the ground state of an odd chain, singly charged or neutral, is a soliton; (2) calculate neutralsoliton creation energies; and (3) prove that "sol...
متن کاملFrustrated spin-Peierls chains.
We study the phase diagram, ground state properties, and excitation gaps of a frustrated spin-Peierls chain, i.e. a spin-Peierls chain with both nearest neighbor exchange J1 and next nearest neighbor exchange J2. The phase diagram is calculated using a bosonization Renormalization-Group (RG) method. We propose a (bosonic) bond-operator mean field approximation to calculate the ground state prop...
متن کاملSpin systems on hypercubic Bethe lattices: A Bethe-Peierls approach
We study spin systems on Bethe lattices constructed from ddimensional hypercubes. Although these lattices are not tree-like, and therefore closer to real cubic lattices than Bethe lattices or regular random graphs, one can still use the Bethe-Peierls method to derive exact equations for the magnetization and other thermodynamic quantities. We compute phase diagrams for ferromagnetic Ising model...
