Melamine-induced synthesis of a structurally perfect kagomé antiferromagnet

We report here a structurally perfect kagomé lattice {[Cu_3(bpy)_6](SiF_6)_3(melamine)_8}_n (1), where bpy is 4,4′-bipyridine and [SiF_6]^2− is a hexafluorosilicate anion. In comparison to general 1D linear, 2D layered and 3D cubic metal–organic frameworks, by using Cu^2+ nodes and bpy ligands, a perfect kagomé lattice was synthesized by introducing C_3 symmetrical melamine molecules. Magnetic susceptibility and low-temperature heat capacity measurements indicated weak antiferromagnetic interactions between the spins and no long-range magnetic ordering to 0.7 K. Using C_3 symmetrical melamine molecules can be considered as a challenging synthetic strategy to afford new topological materials.journal articl

Search for matter-dependent atmospheric neutrino oscillations in Super-Kamiokande

We consider ν_μ→ν_τ oscillations in the context of the mass varying neutrino (MaVaN) model, where the neutrino mass can vary depending on the electron density along the flight path of the neutrino. Our analysis assumes a mechanism with dependence only upon the electron density, hence ordinary matter density, of the medium through which the neutrino travels. Fully-contained, partially-contained and upward-going muon atmospheric neutrino data from the Super-Kamiokande detector, taken from the entire SK-I period of 1489 live days, are compared to MaVaN model predictions.We find that, for the case of 2-flavor oscillations, and for the specific models tested, oscillation independent of electron density is favored over density dependence. Assuming maximal mixing, the best-fit case and the densityindependent case do not differ significantly.journal articl
