Spin wave analysis to the spatially-anisotropic Heisenberg antiferromagnet on triangular lattice
We study the phase diagram at T = 0 of the antiferromagnetic Heisenberg model on the triangular lattice with spatially-anisotropic interactions. For values of the anisotropy very close to Jα/Jβ = 0.5, conventional spin wave theory predicts that quantum fluctuations melt the classical structures, even for arbitrary values of S. From the limit of weakly coupled chains, Jβ << Jα, it is shown that ...
متن کاملOrdering in spatially anisotropic triangular antiferromagnets.
We investigate the phase diagram of the anisotropic spin-1/2 triangular lattice antiferromagnet, with interchain diagonal exchange J' much weaker than the intrachain exchange J. We find that fluctuations lead to a competition between (commensurate) collinear antiferromagnetic and (zigzag) dimer orders. Both states differ in symmetry from the spiral order known to occur for larger J', and are th...
متن کاملQuasiparticles of spatially anisotropic triangular antiferromagnets in a magnetic field.
The spectral properties of the spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice in a magnetic field are investigated using a weak-interchain-coupling approach combined with exact solutions of a chain. Dominant modes induced by interchain interactions in a magnetic field behave as quasiparticles which show distinctive features such as anomalous incommensurate ordering and...
متن کاملTheory of the algebraic vortex liquid in an anisotropic spin - 12 triangular antiferromagnet
We explore spin2 triangular antiferromagnets with both easy-plane and lattice exchange anisotropies by employing a dual vortex mapping followed by a fermionization of the vortices. Over a broad range of exchange anisotropy, this approach leads naturally to a “critical” spin liquid—the algebraic vortex liquid—which appears to be distinct from other known spin liquids. We present a detailed chara...
متن کاملClassical Ring - exchange Processes on the Triangular Lattice ⋆
The effects of the ring-exchange Hamiltonian H3 = J3 ∑ 〈ijk〉(Si · Sj)(Si · Sk) on the triangular lattice are studied using classical Monte Carlo simulations. Each spin Si is treated as a classical XY spin taking on Q equally spaced angles (Q-states clock model). For Q = 6, a first-order transition into a stripe-ordered phase preempts the macroscopic classical degeneracy. For Q > 6, a finite win...
