Kinetic frustration and the nature of the magnetic and paramagnetic states in iron pnictides and iron chalcogenides
Iron-based superconductors all share the same building blocks. So why do local magnetic properties vary from one compound to another? A new theoretical model explains the variation in physical properties and l...

Computational modeling of actinide materials and complexes
In spite of being rare, actinide elements provide the building blocks for many fascinating condensed-matter systems, both from an experimental and theoretical perspective. Experimental observations of actinide...

A first-order Mott transition in LixCoO2
Despite many years of experimental searches for a first-order Mott transition in crystalline-doped semiconductors, none have been found. Extensive experimental work has characterized a first-order metal–insula...
