Polycrystalline samples of Mn2SiO4, Mn2GeO4, Co2SiO4 and Ni2SiO4 were prepared and studied in the context of a search for geometrically frustrated magnetic materials.

The atomic structures of quasicrystalline materials exhibit long range order under translations.

This paper studies three classes of discrete sets X in R(n) which have a weak translational order imposed by increasingly strong restrictions on their sets of interpoint vectors X - X.

As a potential solution to the compact routing problem, geometric routing has been proven to be both simple and heuristically effective.

Segmented flows consist of two immiscible fluids which travel along a channel in a segmented arrangement due to an imposed pressure difference.

When interactions between magnetic degrees of freedom are incompatible with the underlying crystal lattice, exotic phenomena such as spin ice or spin liquid phases can result.

The idea that some systems could have a thermodynamically-large number of accessible ground states was presaged in the work of Pauling on ice.

A comment on "Nonlinear Excitations on a Quantum Ferromagnetic Chain" by R. Balakrishnan and A. R. Bishop, Phys. Rev. Lett. 55, 537 (1985).

Three classes of monosubstituted carbenes (aryl-, vinyl-, carbonyl- ) and one class of disubstituted carbenes (dicarbonyl-), all of them ground state triplets, can exist in more than one rotameric

In a number of experiments, 1 2 3 propagation of magnetoelastic waves has been observed in discs and rods of y t t r i u m iron garnet.
