Bulk sensitive x-ray absorption spectroscopy free of self-absorption effects
A. J. Achkar, T. Z. Regier, H. Wadati +3
We demonstrate a new method of x-ray absorption spectroscopy (XAS) that is bulk sensitive, like traditional fluorescence yield measurements, but is not affected by self-absorption…
Charge-Transfer Excitations in the Model Superconductor HgBaCuO
L. Lu, X. Zhao, G. Chabot-Couture +9
We report a Cu -edge resonant inelastic x-ray scattering (RIXS) study of charge-transfer excitations in the 2-8 eV range in the structurally simple compound HgBaCuO…
Resonant inelastic x-ray scattering study of holon-antiholon continuum in SrCuO2
Young-June Kim, J. P. Hill, H. Benthien +9
We report a resonant inelastic x-ray scattering study of charge excitations in the quasi-one-dimensional Mott insulator SrCuO2. We observe a continuum of low-energy excitations, in…
Resonant inelastic x-ray scattering study of charge excitations in La2CuO4
Y. J. Kim, J. P. Hill, C. A. Burns +5
We report a resonant inelastic x-ray scattering study of the dispersion relations of charge transfer excitations in insulating LaCuO. These data reveal two peaks, both of w…
Monte Carlo Study of the S=1/2 and S=1 Heisenberg Antiferromagnet on a Spatially Anisotropic Square Lattice
Y. J. Kim, R. J. Birgeneau
We present a quantum Monte Carlo study of a Heisenberg antiferromagnet on a spatially anisotropic square lattice, where the coupling strength in the x-direction () is differen…
Monte Carlo Study of Correlations in Quantum Spin Chains at Non-Zero Temperature
Y. J. Kim, M. Greven, U. -J. Wiese +1
Antiferromagnetic Heisenberg spin chains with various spin values () are studied numerically with the quantum Monte Carlo method. Effective spin chains are r…
