Antiferromagnetic spin ladders: Crossover between spin S=1/2 and S=1 chains.
We study a model of two weakly coupled isotropic spin-1/2 Heisenberg chains with an antiferromagnetic coupling along the chains (spin ladder). It is shown that the system always has a spectral gap. For the case of identical chains the model in the continuous limit is shown to be equivalent to four decoupled non-critical Ising models with the Z 2 ×SU(2)-symmetry. For this case we obtain the exac...

متن کاملWeakly disordered spin ladders
We analyze an anisotropic spin 1/2 two legs ladder in the presence of various type of random perturbations. The generic phase diagram for the pure system, in a way similar to spin one chains, consists of four phases: an Antiferromagnet, a Haldane gap or a Singlet phase (depending on the sign of interchain coupling) and two XY phases designated by XY1 and XY2. The effects of disorder depend cruc...
متن کاملLong - range spin - pairing order and spin defects in quantum spin - 1 2 ladders
For w-legged antiferromagnetic spin-1/2 Heisenberg ladders, a long-range spin pairing order can be identified which enables the separation of the space spanned by finite-range (covalent) valence-bond configurations into w + 1 subspaces. Since every subspace has an equivalent counter subspace connected by translational symmetry, twofold degeneracy, breaking translational symmetry is found except...
متن کاملAnomalous magnetization process in frustrated spin ladders
We study, at T = 0, the anomalies in the magnetization curve of the S = 1 two-leg ladder with frustrated interactions. We focus mainly on the existence of the M = Ms/2 plateau, where Ms is the saturation magnetization. We reports the results by degenerate perturbation theory and and the density matrix renormalization group, which lead to the consistent conclusion with each other. We also touch ...
