We review oxygen K-edge X-ray absorption spectra of both molecules and solids. We start
with an overview of the main experimental aspects of oxygen K-edge X-ray absorption …

In the past decade, resonant inelastic x-ray scattering (RIXS) has made remarkable progress
as a spectroscopic technique. This is a direct result of the availability of high-brilliance …

Advances in growth technology of oxide materials allow single atomic layer control of
heterostructures. In particular delta do**, a key materials' engineering tool in today's …

In the series of 3d (t 2g) 1 perovskites, SrVO 3–CaVO 3–LaTiO 3–YTiO 3, the transition-
metal d electron becomes increasingly localized and undergoes a Mott transition between …

In systems with strong electron-lattice coupling, such as manganites, orbital degeneracy is
lifted, causing a null expectation value of the orbital magnetic moment. Magnetic structure is …

The simple ABO3 and A-site-ordered AA′ 3B4O12 perovskites represent two types of
classical perovskite functional materials. There are well-known simple perovskites with …

Strongly‐correlated transition‐metal oxides are widely known for their various exotic
phenomena. This is exemplified by rare‐earth nickelates such as LaNiO3, which possess …

A detailed analysis of the crystal structure in R Ti O 3 with R= La, Nd, Sm, Gd, and Y reveals
an intrinsic coupling between orbital degrees of freedom and the lattice which cannot be …

The Mott transistor is a paradigm for a new class of electronic devices—often referred to by
the term Mottronics—which are based on charge correlations between the electrons. Since …

We present an approach to computing multiplets for core spectroscopies, whereby the
crystal field is constructed explicitly from the positions and charges of surrounding atoms …
