Octupolar order in the multiple spin exchange model on a triangular lattice.
نویسندگان
چکیده
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...
متن کاملSpin Bose - metal phase in a spin - 12 model with ring exchange on a two - leg triangular strip
Recent experiments on triangular lattice organic Mott insulators have found evidence for a two-dimensional 2D spin liquid in close proximity to the metal-insulator transition. A Gutzwiller wave function study of the triangular lattice Heisenberg model with a four-spin ring exchange term appropriate in this regime has found that the projected spinon Fermi sea state has a low variational energy. ...
متن کاملQuantum spin ices and topological phases from dipolar-octupolar doublets on the pyrochlore lattice.
We consider a class of d- and f-electron systems in which dipolar-octupolar Kramers doublets arise on the sites of the pyrochlore lattice. For such doublets, two components of the pseudospin transform like a magnetic dipole, while the other transforms like a component of the magnetic octupole tensor. Based on a symmetry analysis, we construct and study models of dipolar-octupolar doublets in it...
متن کاملMultiple-Spin Exchange on a Triangular Lattice: A Quantitative Interpretation of Thermodynamic Properties of Two-Dimensional Solid
We apply exact high-temperature series expansions of the multiple-spin-exchange Hamiltonian for a triangular lattice to describe high precision NMR measurements of the nuclear magnetic susceptibility of 3He films adsorbed on graphite, reported here, as well as all available specific heat data. A consistent quantitative description of the unusual thermodynamic properties of the second layer soli...
متن کاملOctupolar ordering of Γ8 ions in magnetic field
Motivated by the recent suggestion that the 25K phase transition of NpO2 may be explained as octupolar ordering, we study f -electron lattice models which are capable of supporting octupolar, as well dipolar and quadrupolar order. Analyzing the properties of the Γ8 ground state quartet, we find that (111)-type combinations of the Γ5 octupoles T β 111 = T β x +T β y +T β z are the best candidate...
