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 …

Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one
of the most actively studied subjects in condensed matter physics, as correlations and SOC …

Complex oxides with 4 d and 5 d transition-metal ions recently emerged as a new paradigm
in correlated electron physics, due to the interplay between spin–orbit coupling and electron …

We investigated the electronic structure of 5 d transition-metal oxide Sr 2 IrO 4 using angle-
resolved photoemission, optical conductivity, x-ray absorption measurements, and first …

To meet strong demands for the control of thermal expansion necessary because of the
advanced development of industrial technology, widely various giant negative thermal …

In Mott insulators with the t 2 g 4 electronic configuration such as of Re 3+, Ru 4+, Os 4+,
and Ir 5+ ions, spin-orbit coupling dictates a Van Vleck–type nonmagnetic ground state with …

Condensed-matter analogues of the Higgs boson in particle physics allow insights into its
behaviour in different symmetries and dimensionalities. Evidence for the Higgs mode has …

An extensive introduction to spin-orbit coupling (SOC) is presented, starting from a
discussion of the phenomenological operators and general chemical importance of SOC to …

Mott insulators with strong spin-orbit coupling have been proposed to host unconventional
magnetic states, including the Kitaev quantum spin liquid. The 4 d system α-RuCl 3 has …

We present a first-principles study of spin-orbit coupling effects on the Fermi surface of Sr 2
RuO 4 and Sr 2 RhO 4. For nearly degenerate bands, spin-orbit coupling leads to a dramatic …
