Uniform and staggered magnetizations induced by Dzyaloshinskii-Moriya interactions in isolated and coupled spin 1/2 dimers in a magnetic field
S. Miyahara, J. -B. Fouet, S. R. Manmana +5
We investigate the interplay of Dzyaloshinskii-Moriya interactions and an external field in spin 1/2 dimers. For isolated dimers and at low field, we derive simple expressions for…
Dynamics of the quantum dimer model on the triangular lattice: Soft modes and local resonating valence-bond correlations
Arnaud Ralko, Michel Ferrero, Federico Becca +2
We report on an exhaustive investigation of the dynamical dimer-dimer correlations in imaginary time for the quantum dimer model on the triangular lattice using the Green's functio…
Checkerboard order in the t--J model on the square lattice
D. Poilblanc, C. Weber, F. Mila +1
We propose that the inhomogeneous patterns seen by STM in some underdoped superconducting cuprates could be related to a bond-order-wave instability of the staggered flux state, on…
The quadrupolar phases of the S=1 bilinear-biquadratic Heisenberg model on the triangular lattice
A. Laeuchli, F. Mila, K. Penc
Using mean-field theory, exact diagonalizations and SU(3) flavour theory, we have precisely mapped out the phase diagram of the S=1 bilinear-biquadratic Heisenberg model on the tri…
Condensation of magnons and spinons in a frustrated ladder
J. -B. Fouet, F. Mila, D. Clarke +4
Motivated by the ever-increasing experimental effort devoted to the properties of frustrated quantum magnets in a magnetic field, we present a careful and detailed theoretical anal…
Identification of an RVB liquid phase in a quantum dimer model with competing kinetic terms
Francois Vernay, Arnaud Ralko, Federico Becca +1
Starting from the mean-field solution of a spin-orbital model of LiNiO, we derive an effective quantum dimer model (QDM) that lives on the triangular lattice and contains kinet…
