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 …

Resonant inelastic X-ray scattering (RIXS) is a powerful technique that combines
spectroscopy and inelastic scattering to probe the electronic structure of materials. RIXS is …

Quantum spin liquids are an exciting playground for exotic physical phenomena and
emergent many-body quantum states. The realization and discovery of quantum spin liquid …

An overview of both experimental and theoretical results in the field of resonant scattering of
tunable soft and hard x-ray radiation is presented, with a main focus on the closely related …

Understanding quantum materials—solids in which interactions among constituent electrons
yield a great variety of novel emergent quantum phenomena—is a forefront challenge in …

The quasi-two-dimensional Shastry-Sutherland model has remained topical in the field of
condensed matter physics for the last two decades, following the experimental realization of …

We report the measurement of impulsive stimulated x-ray Raman scattering in neutral liquid
water. An attosecond pulse drives the excitations of an electronic wavepacket in water …

The microscopic origins of emergent behaviours in condensed matter systems are encoded
in their excitations. In ordinary magnetic materials, single spin-flips give rise to collective …

Motivated by recent advancements in theoretical and experimental studies of the high-
energy excitations on an antiferromagnetic trimer chain, we numerically investigate the …

Although many experiments imply that oxygen orbitals play an essential role in the high-
temperature superconducting cuprates, their precise role in collective spin and charge …
