Classical 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...

Octupolar order in the multiple spin exchange model on a triangular lattice.

We show how a gapless spin liquid with hidden octupolar order arises in an applied magnetic field, in a model applicable to thin films of 3He with competing ferromagnetic and antiferromagnetic (cyclic) exchange interactions. Evidence is also presented for nematic--i.e., quadrupolar--correlations bordering on ferromagnetism in the absence of a magnetic field.

Non - Degenerate Ground State in the Antiferromagnetic Double - Exchange Model on a Triangular Lattice

In order to study effects of frustration in an itinerant electron system, we investigate ground states of the antiferromagnetic double-exchange model on a triangular lattice. In this model, pseudo-spins are coupled to electron transfer integrals in such a way that antiparallel configurations of pseudo-spins gain kinetic energies. Although the antiferromagnetic Ising model on a triangular lattic...

Dimer model on a triangular lattice.

We analyze the partition function of the dimer model on an M×N triangular lattice wrapped on a torus obtained by Fendley, Moessner, and Sondhi [Phys. Rev. B 66, 214513 (2002)]. From a finite-size analysis we have found that the dimer model on such a lattice can be described by a conformal field theory having a central charge c=-2. The shift exponent for the specific heat is found to depend on t...

Pair-density-wave correlations in the Kondo-Heisenberg model.

We show, using density-matrix renormalization-group calculations complemented by field-theoretic arguments, that the spin-gapped phase of the one dimensional Kondo-Heisenberg model exhibits quasi-long-range superconducting correlations only at a nonzero momentum. The local correlations in this phase resemble those of the pair-density-wave state which was recently proposed to describe the phenom...
