Correlations and confinement in non-planar two-dimensional dimer models
A. W. Sandvik, R. Moessner
We study classical hard-core dimer models on the square lattice with links extending beyond nearest-neighbors. Numerically, using a directed-loop Monte Carlo algorithm, we find tha…
Why spin ice obeys the ice rules
S. V. Isakov, R. Moessner, S. L. Sondhi
The low temperature entropy of the the spin ice compounds, such as HoTiO and DyTiO, is well described by the nearest-neighbor antiferromagnetic Ising model…
Flux expulsion and greedy bosons: frustrated magnets at large N
O. Tchernyshyov, R. Moessner, S. L. Sondhi
We investigate the Sp(N) mean-field theory for frustrated quantum magnets. First, we establish some general properties of its solutions; in particular, for small spin we propose si…
Magnetization process of spin ice in a [111] magnetic field
S. V. Isakov, K. S. Raman, R. Moessner +1
Spin ice in a magnetic field in the [111] direction displays two magnetization plateaux, one at saturation and an intermediate one with finite entropy. We study the crossovers betw…
Valence-bond crystal in a {111} slice of the pyrochlore antiferromagnet
Oleg Tchernyshyov, Hong Yao, R. Moessner
We investigate theoretically the ordering effect of quantum spin fluctuations in a Heisenberg antiferromagnet on a two-dimensional network of corner sharing tetrahedra. This networ…
On bipartite Rokhsar-Kivelson points and Cantor deconfinement
Eduardo Fradkin, David A. Huse, R. Moessner +2
Quantum dimer models on bipartite lattices exhibit Rokhsar-Kivelson (RK) points with exactly known critical ground states and deconfined spinons. We examine generic, weak, perturba…
