Non-perturbative series expansion of Green's functions: The Anatomy of Resonant Inelastic X-Ray Scattering in Doped Hubbard Model
Yi Lu, Maurits W. Haverkort
We present a non-perturbative, divergence-free series expansion of Green's functions using effective operators. The method is especially suited for computing correlators of complex…
calculation of the calorimetric electron capture spectrum of Holmium: Intra-atomic decay into bound-states
M. Braß, C. Enss, L. Gastaldo +1
The determination of the electron neutrino mass by electron capture in Ho relies on a precise understanding of the deexcitation of a core hole after an electron capture eve…
The -axis dimer and its electronic break-up: the insulator-to-metal transition in TiO
C. F. Chang, T. C. Koethe, Z. Hu +17
We report on our investigation of the electronic structure of TiO using (hard) x-ray photoelectron and soft x-ray absorption spectroscopy. From the distinct satellite struc…
Lattice and Magnetic Effects on a d-d Excitation in NiO Using a 25 meV Resolution X-ray Spectrometer
Daisuke Ishikawa, Maurits W. Haverkort, Alfred Q. R. Baron
We investigate the behavior of a - transition in NiO using a new x-ray spectrometer with 0.025 eV resolution at 15816 eV, and via ab-initio ligand field theory calculations.…
Maximal Rashba-like spin splitting via kinetic energy-driven inversion symmetry breaking
Veronika Sunko, H. Rosner, P. Kushwaha +13
Engineering and enhancing inversion symmetry breaking in solids is a major goal in condensed matter physics and materials science, as a route to advancing new physics and applicati…
Crossover from Collective to Incoherent Spin Excitations in Superconducting Cuprates Probed by Detuned Resonant Inelastic X-ray Scattering
M. Minola, Y. Lu, Y. Y. Peng +22
Spin excitations in the overdoped high temperature superconductors TlBaCuO and (Bi,Pb)(Sr,La)CuO were investigated by resonant inelastic x-ray sca…
