Charge density wave fluctuations, heavy electrons, and superconductivity in KNiS
James R. Neilson, Anna Llobet, Jiajia Wen +2
Understanding the complexities of electronic and magnetic ground states in solids is one of the main goals of solid-state physics. Materials with the canonical ThCrSi-type…
Epitaxial growth of (111)-oriented LaAlO/LaNiO ultra-thin superlattices
S. Middey, D. Meyers, M. Kareev +5
The epitaxial stabilization of a single layer or superlattice structures composed of complex oxide materials on polar (111) surfaces is severely burdened by reconstructions at the…
Symmetry and correlations underlying Hidden Order in URu2Si2
Nicholas P. Butch, Michael E. Manley, Jason R. Jeffries +6
We experimentally investigate the symmetry in the Hidden Order (HO) phase of intermetallic URu2Si2 by mapping the lattice and magnetic excitations via inelastic neutron and x-ray s…
Topological states in pyrochlore iridates: long-range anisotropy strongly competing with spin-orbit interaction
Liviu Hozoi, H. Gretarsson, J. P. Clancy +7
In the search for topological phases in correlated electron systems, iridium-based pyrochlores A2Ir2O7 -- materials with 5d transition-metal ions -- provide fertile grounds. Severa…
Doping Evolution of Oxygen K-edge X-ray Absorption Spectra in Cuprate Superconductors
C. -C. Chen, M. Sentef, Y. F. Kung +5
We study oxygen K-edge x-ray absorption spectroscopy (XAS) and investigate the validity of the Zhang-Rice singlet (ZRS) picture in overdoped cuprate superconductors. Using large-sc…
Strongly momentum-dependent screening dynamics in LaSrMnO observed with resonant inelastic x-ray scattering
X. Liu, T. F. Seman, K. H. Ahn +6
We report strongly momentum-dependent local charge screening dynamics in CE-type charge, orbital, and spin ordered LaSrMnO, based on Mn K-edge resonant inelasti…
