This article reviews the physics of multipolar interactions and multipolar order in f-electron
systems, using the actinide dioxides as a paradigm. In the past few years, these apparently …

Research on actinide materials, both basic and applied, has been greatly advanced by the
general techniques available from high-intensity photon beams from x-ray synchrotron …

A methodology for the rigorous nonperturbative derivation of magnetic pseudospin
Hamiltonians of mononuclear complexes and fragments based on ab initio calculations of …

This Feature Article seeks to present the current state of knowledge, both experimental and
theoretical, of the electronic structure and bonding in actinyl ions and related species, such …

We report a study of the ground state and metastable states of uranium dioxide using ab
initio DFT+ U calculations. We highlight that in order to avoid metastable states and …

The detrimental effects of the fission gas Xe on the performance of oxide nuclear fuels are
well known. However, less well known are the mechanisms that govern fission gas …

Raman spectra of stoichiometric and hyperstoichiometric uranium dioxide are presented, as
measured on nuclear-grade UO2 pellets treated under oxidising conditions to obtain …

This work provides an illustration that density functional theory (DFT)+ U calculations may
quantitatively describe transport phenomena in uranium dioxide. Oxygen diffusion …

The phonon Raman scattering in UO 2 was investigated under pressures up to 29 GPa with
the excitation energy range of E i= 1.16–2.41 eV. At ambient pressure up to the sixth order …

The multipole concept, which characterizes the spacial distribution of scalar and vector
objects by their angular dependence, has already become widely used in various areas of …
