Charge-orbital-lattice coupling effects in the dd-excitation profile of one dimensional cuprates
J. J. Lee, B. Moritz, W. S. Lee +12
We identify dd-excitations in the quasi-one dimensional compound CaYCuO using resonant inelastic x-ray scattering. By tuning across the Cu L-edge, we observe…
Orbital control of effective dimensionality: from spin-orbital fractionalization to confinement in the anisotropic ladder system CaCu2O3
Valentina Bisogni, Krzysztof Wohlfeld, Satoshi Nishimoto +11
Fractionalization of an electronic quasiparticle into spin, charge and orbital parts is a fundamental and characteristic property of interacting electrons in one dimension. However…
Femtosecond dynamics of magnetic excitations from resonant inelastic x-ray scattering in CaCu2O3
Valentina Bisogni, Stefanos Kourtis, Claude Monney +10
Taking spinon excitations in the quantum antiferromagnet CaCu2O3 as an example, we demonstrate that femtosecond dynamics of magnetic excitations can be probed by direct resonant in…
Evolution of the SrTiO surface electronic state as a function of LaAlO overlayer thickness
N. C. Plumb, M. Kobayashi, M. Salluzzo +10
The novel electronic properties emerging at interfaces between transition metal oxides, and in particular the discovery of conductivity in heterostructures composed of LaAlO (L…
Mixed Dimensionality of Confined Conducting Electrons in the Surface Region of SrTiO
N. C. Plumb, M. Salluzzo, E. Razzoli +16
Using angle-resolved photoemission spectroscopy, we show that the recently-discovered surface state on SrTiO consists of non-degenerate states with different dimensi…
The Role of Lattice Coupling in Establishing Electronic and Magnetic Properties in Quasi-One-Dimensional Cuprates
W. S. Lee, S. Johnston, B. Moritz +11
High resolution resonant inelastic x-ray scattering has been performed to reveal the role of lattice-coupling in a family of quasi-1D insulating cuprates, CaYCu$_…
Persistent high-energy spin excitations in iron pnictide superconductors
K. J. Zhou, Y. B. Huang, C. Monney +10
Motivated by the premise that superconductivity in iron-based superconductors is unconventional and mediated by spin fluctuations, an intense research effort has been focused on ch…
