Hidden Orders and RVB formation of the Four-Leg Heisenberg Ladder Model
نویسندگان
چکیده
The ground state of the four-chain Heisenberg ladder model is numerically investigated. Hiddenorder correlations suitable for the system are introduced and calculated with an emphasis on the spatially isotropic point, where a corresponding material exists. The existence of a long-range hidden correlation indicates formation of a short-range RVB state in the case of the antiferromagnetic inter-chain coupling. A transition between the phase of the ferromagnetic inter-chain coupling and that of the antiferromagnetic one is discussed.

Dimer–resonating valence bond state of the four-leg Heisenberg ladder: Interference among resonances
Doped and undoped ladders have focused a lot of attention in recent years due to the existence of materials with that structure; some of them are close relatives of the high-Tc oxides as the series Sr2nl22Cu2nlO4nl22 where nl is the number of legs forming the ladder. The undoped Heisenberg spin ladders with nl even are known to be spin liquids with a spin gap and exponential decaying correlatio...

It is shown that the problem of calculating spin-spin correlation functions, in the dimers RVB states, on a possibly diluted 2D square lattice, can be formulated in terms of a transfer matrix. The transfer matrix is used for exact numerical calculations of spin-spin correlation functions on ladders up to four units wide. Typeset using REVTEX 1 In the last few years, the class of Resonating Vale...

We consider RVB state as a variational estimate for the ground state of Heisenberg antiferromagnet in square lattice. We present numerical calculation of energy, spin-spin correlation function and spin excitation spectrum. We show, that the quantum flactuations reduce of magnetization respect to Neel order. Our results are in good agreement with other methods such as spin-wave calculation a...
متن کاملSpin Bose-metal and valence bond solid phases in a spin-1/2 model with ring exchanges on a four-leg triangular ladder.
We study a spin-1/2 system with Heisenberg plus ring exchanges on a four-leg triangular ladder using the density matrix renormalization group and Gutzwiller variational wave functions. Near an isotropic lattice regime, for moderate to large ring exchanges we find a spin Bose-metal phase with a spinon Fermi sea consisting of three partially filled bands. Going away from the triangular towards th...
متن کاملOptimizing the RVB state on a triangular lattice: Presence of the long-range order
We present a Schwinger-boson approach for the RVB state of the spin-1/2 Heisenberg antiferromagnet on a triangular lattice. It is shown that a Gutzwiller projection of the mean-field state that includes both antiferromagnetic and ferromagnetic decouplings leads to optimizing the RVB pair amplitudes within a self-consistent approximation. The resulting state yields, by Monte Carlo simulations, e...
