Competition between plaquette and dimer phases in Heisenberg chains
نویسنده
چکیده
We consider a class of one-dimensional Heisenberg spin models (plaquette chains) related to the recently found 1/5-depleted square-lattice Heisenberg system CaV4O9. A number of exact and exact-numerical results concerning the properties of the competing dimer and resonating plaquette phases are presented.

Spin Gap in Two-Dimensional Heisenberg Model for CaV4O9
ABSTRACT: We investigate the mechanism of spin gap formation in a two-dimensional model relevant to Mott insulators such as CaV4O9. From the perturbation expansion and quantum Monte Carlo calculations, the origin of the spin gap is ascribed to the four-site plaquette singlet in contrast to the dimer gap established in the generalized dimerized Heisenberg model. We investigate the mechanism of s...
متن کاملPlaquette ordered phase and quantum spin liquid in the spin- 2 J1-J2 square Heisenberg model
We study the spin1 2 Heisenberg model on the square lattice with firstand second-neighbor antiferromagnetic interactions J1 and J2, which possesses a nonmagnetic region that has been debated for many years and might realize the interesting Z2 spin liquid (SL). We use the density matrix renormalization group approach with explicit implementation of SU(2) spin rotation symmetry and study the mode...

We examine the ground state and the excitations of an one-dimensional Heisenberg spin 1/2 antiferromagnet with alternating dimers and four-spin plaquettes (dimer-plaquette chain). The properties of the system depend on the competing dimer and plaquette bonds. Several exact, exact-numerical and perturbational results are presented. We find that the system is gapped for all parameter values. The ...
متن کاملDimer order with striped correlations in the J1-J2 Heisenberg model
Ground-state energies for plaquette and dimer order in the J1-J2 square-lattice spin-half Heisenberg model are compared using series expansion methods. We find that these energies are remarkably close to each other at intermediate values of J2 /J1 , where the model is believed to have a quantum disordered ground state. They join smoothly with those obtained from the Ising expansions for the two...
متن کاملValence bond solid phases in a cubic antiferromagnet.
We report on a valence bond projector Monte Carlo simulation of the cubic lattice quantum Heisenberg model with additional higher-order exchange interactions in each unit cell. The model supports two different valence bond solid (VBS) ground states. In one of these states, the dimer pattern is a three-dimensional analogue of the columnar pattern familiar from two dimensions. In the other, the d...
