Charge-ordered resonating valence bond states in doped cuprates

We study charge ordered d-wave resonating valence bond states sdRVBd in the doped cuprates, and estimate the energies of these states in a generalized t-J model by using a renormalized mean-field theory. The longrange Coulomb potential tends to modulate the charge density in favor of the charge ordered RVB state. The possible relevance to the recently observed 434 checkerboard patterns in tunne...

Bosonic 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...

Temperley–Lieb Words as Valence-Bond Ground States

Based on the Temperley–Lieb algebra we define a class of one-dimensional Hamiltonians with nearest and next-nearest neighbour interactions. Using the regular representation we give ground states of this model as words of the algebra. Two point correlation functions can be computed employing the Temperley–Lieb relations. Choosing a spin2 representation of the algebra we obtain a generalization o...

Half-filled layered organic superconductors and the resonating-valence-bond theory of the hubbard-heisenberg model.

We present a resonating-valence-bond theory of superconductivity for the Hubbard-Heisenberg model on an anisotropic triangular lattice. Our calculations are consistent with the observed phase diagram of the half-filled layered organic superconductors, such as the beta, beta', kappa, and lambda phases of (BEDT-TTF)2X [bis(ethylenedithio)tetrathiafulvalene] and (BETS)2X [bis(ethylenedithio)tetras...
