Analytical theory for proton correlations in common water ice
S. V. Isakov, R. Moessner, S. L. Sondhi +1
We provide a fully analytical microscopic theory for the proton correlations in water ice . We compute the full diffuse elastic neutron scattering structure factor, which we f…
Fibonacci topological order from quantum nets
Paul Fendley, Sergei V. Isakov, Matthias Troyer
We analyze a model of quantum nets and show it has non-abelian topological order of doubled Fibonacci type. The ground state has the same topological behavior as that of the corres…
Topological Phases: An Expedition off Lattice
Michael H. Freedman, Lukas Gamper, Charlotte Gils +3
Motivated by the goal to give the simplest possible microscopic foundation for a broad class of topological phases, we study quantum mechanical lattice models where the topology of…
Classical antiferromagnet on a hyperkagome lattice
John M. Hopkinson, Sergei V. Isakov, Hae-Young Kee +1
Motivated by recent experiments on Na_4Ir_3O_8 [Y. Okamoto, M. Nohara, H. Aruga-Katori, and H. Takagi, arXiv:0705.2821 (unpublished)], we study the classical antiferromagnet on a f…
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…
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…
