RVB description of the low-energy singlets of the spin 1/2 kagomé antiferromagnet
Extensive calculations in the short-range RVB (Resonating valence bond) subspace on both the trimerized and the regular (non-trimerized) Heisenberg model on the kagomé lattice show that short-range dimer singlets capture the specific low-energy features of both models. In the trimerized case the singlet spectrum splits into bands in which the average number of dimers lying on one type of bonds ...
متن کاملValence Bond Ground States in a Frustrated Two-Dimensional Spin-1/2 Heisenberg Antiferromagnet
We study a class of two-dimensional spin-1/2 Heisenberg antiferromagnets, introduced by Klein [1], in which the nearest-neighbor term is supplemented by next-nearest-neighbor pair and four-body interactions, producing additional frustration. For certain lattices, including e.g. the hexagonal lattice, we prove that any finite subset which admits a dimer covering has a ground state space spanned ...
متن کاملResonating valence bond phase in the triangular lattice quantum dimer model.
We study the quantum dimer model on the triangular lattice, which is expected to describe the singlet dynamics of frustrated Heisenberg models in phases where valence bond configurations dominate their physics. We find, in contrast to the square lattice, that there is a truly short ranged resonating valence bond phase with no gapless excitations and with deconfined, gapped, spinons for a finite...
متن کاملQuantum effects in a weakly frustrated s=1/2 two-dimensional heisenberg antiferromagnet in an applied magnetic field.
We have studied the two-dimensional S=1/2 square-lattice antiferromagnet Cu(pz)_{2}(ClO4)_{2} (where pz denotes pyrazine), using neutron inelastic scattering and series expansion calculations. We show that the presence of antiferromagnetic next-nearest-neighbor interactions enhances quantum fluctuations associated with resonating valence bonds. Intermediate magnetic fields lead to a selective t...
متن کاملBosonic Resonating-Valence-Bond Description of a Doped Antiferromagnet
We propose a theory for a doped antiferromagnet based on the bosonic resonating-valence-bond (RVB) description incorporating the phase string effect. Both antiferromagnetic and superconducting phase transitions occur naturally inside such a bosonic RVB phase. Two distinct metallic regions— underdoping and optimum doping—are also found to be a logical consequence; their unique features explain t...
