Dynamics of weakly coupled random antiferromagnetic quantum spin chains
We study the low-energy collective excitations and dynamical response functions of weakly coupled random antiferromagnetic spin-1 /2 chains. The interchain coupling leads to Néel order at low temperatures. We use the real-space renormalization-group technique to tackle the intrachain couplings and treat the interchain couplings within the random phase approximation RPA . We show that the system...
متن کاملWeakly Coupled Antiferromagnetic Quantum Spin Chains
Quasi-one-dimensional quantum antiferromagnets formed by a d-dimensional hypercubic lattice of weakly coupled spin-1/2 antiferromagnetic Heisenberg chains are studied by combining exact results in one-dimension and renormalization group analyses of the interchain correlations. It is shown that d-dimensional magnetic long-range order develops at zero-temperature for infinitesimal antiferromagnet...
متن کاملRandom antiferromagnetic SU„N... spin chains
We analyze random isotropic antiferromagnetic SUsNd spin chains using the real-space renormalization group. We find that they are governed at low energies by a universal infinite randomness fixed point different from the one of random spin-1 /2 chains. We determine analytically the important exponents: the energy-length scale relation is V,exps−Lcd, where c=1/N, and the mean correlation functio...
متن کاملThree-Dimensional Ordering in Weakly Coupled Antiferromagnetic Ladders and Chains
A theoretical description is presented for low-temperature magnetic-field induced threedimensional (3D) ordering transitions in strongly anisotropic quantum antiferromagnets, consisting of weakly coupled antiferromagnetic spin-1/2 chains and ladders. First, effective continuum field theories are derived for the one-dimensional subsystems. Then the Luttinger parameters, which determine the low-t...
متن کاملSpin-density Wave in Ising-coupled Antiferromagnetic Chains
The effect of anisotropy in the nearest-neighbor spin interactions that couple N ≥ 2 consecutive spin-1/2 antiferromagnetic chains is studied theoretically by considering the limit where the coupling is purely of the Ising type. An analysis based on the equivalent Luttinger model reveals that the groundstate is an Ising antiferromagnet in general. PACS Indices: 75.10.Jm, 75.30.Fv, 75.30.Gw, 74....
