S ep 1 99 8 Critical properties of S = 12 Heisenberg ladders in magnetic fields
The critical properties of the S = 1/2 Heisenberg two-leg ladders are investigated in a magnetic field. Combining the exact diagonalization method and the finite-size-scaling analysis based on conformal field theory, we calculate the critical exponents of spin correlation functions numerically. For a strong interchain coupling, magnetization dependence of the critical exponents shows characteri...
متن کاملMagnetic Properties of Zig - Zag Ladders ∗
We analyze the phase diagram of a system of spin-1/2 Heisenberg antiferromagnetic chains interacting through a zigzag coupling, also called zigzag ladders. Using bosonization techniques we study how a spin-gap or more generally plateaux in magnetization curves arise in different situations. While for coupled XXZ chains, one has to deal with a recently discovered chiral perturbation, the couplin...
متن کاملCritical and off-critical properties of the XXZ chain in external homogeneous and staggered magnetic fields
The phase diagram of the XXZ chain under the influence of homogeneous and staggered magnetic fields is calculated. The model has a rich phase structure with three types of phases. A fully ferromagnetic phase, an antiferromagnetic phase and a massless phase with partial ferromagnetic and antiferromagnetic order. This massless phase has its critical fluctuations governed by a conformal field theo...

model parameter. One may also ask whether a potential phase of flux tube clusters would affect the transport properties of the core in a detectable way. Moreover, it would be interesting to employ our results in studies of the time evolution of the magnetic field in a neutron star. Here we have computed the ground state in equilibrium for given temperature, magnetic field and chemical potential...
