Artificial spin ices consist of nanomagnets arranged on the sites of various periodic and
aperiodic lattices. They have enabled the experimental investigation of a variety of …

Certain lattice wave systems in translationally invariant settings have one or more spectral
bands that are strictly flat or independent of momentum in the tight binding approximation …

In this work, we present our discovery and characterization of a new kagome prototype
structure, KV 3 Sb 5. We also present the discovery of the isostructural compounds RbV 3 Sb …

Spin liquids are collective phases of quantum matter that have eluded discovery in
correlated magnetic materials for over half a century. Theoretical models of these enigmatic …

At the end of a rush lasting over half a century, in which CMOS technology has been
experiencing a constant and breathtaking increase of device speed and density, Moore's …

Defect engineering in metal–organic frameworks (MOFs) is an exciting concept for tailoring
material properties, which opens up novel opportunities not only in sorption and catalysis …

Research on metal–organic framework (MOF) materials has gathered increasing interest
starting from the early excitement as porous materials for gas storage down to various novel …

The spin ice materials, including Ho 2 Ti 2 O 7 and Dy 2 Ti 2 O 7, are rare-earth pyrochlore
magnets which, at low temperatures, enter a constrained paramagnetic state with an …

Frustration, the presence of competing interactions, is ubiquitous in the physical sciences
and is a source of degeneracy and disorder, which in turn gives rise to new and interesting …

Linear spin wave theory provides the leading term in the calculation of the excitation spectra
of long-range ordered magnetic systems as a function of $1/\sqrt {S} $. This term is acquired …
