  • EuIn2As2 is a candidate as an axion insulator, a material that can host axion-like quasi-particles, in direct analogy with the axion proposed in particle physics to resolve the so called “strong CP problem”. Here Soh et al., perform resonant elastic X-Ray scattering on EuIn2As2 and show that the magnetic order consists of commensurate chiral magnetic structures, satisfying the symmetry requirements for EuIn2As2 to be an axion insulator.’

  • The fate of high-energy degrees of freedom, such as spin-orbit interactions, in the coherent state of Kondo lattice materials remains unclear. Here, the authors use resonant inelastic x-ray scattering in CePd3 to show how Kondo-quasiparticle excitations are renormalized and develop a pronounced momentum dependence, while maintaining a largely unchanged spin-orbit gap.
