Symmetric estimator for discrete self-energy of discrete many-body systems
Aleksandrs Zacinskis, Frank T. Ebel, Mathias Pelz +5
We derive a discrete spectral representation of the single-particle self-energy using a discrete evaluation of Kugler's symmetric improved estimator. Our construction can be used o…
Kondo scaling of -electron states and the Kondo singlet breakdown in heavy fermions
B. Tegomo Chiogo, M. Tagliavini, D. Wong +10
The low-energy spin- and charge-sensitive thermodynamic properties of a broad range of strongly correlated 4f-electron systems follow Kondo scaling, with a characteristic Kondo tem…
Direct Evidence of a Near-Ideal Jeff = 1/2 Ground State in Triangular-Lattice Na2BaCo(PO4)2
M. M. Ferreira-Carvalho, S. H. Chen, Y. C. Ku +7
We investigated the local Co 3d electronic structure of Na2BaCo(PO4)2 using polarization-dependent X-ray absorption spectroscopy (XAS) in combination with full multiplet cluster ca…
Critical behavior and evidence of dimensional crossover in quasi-two-dimensional LiFeSiO
Waldemar Hergett, Kevin Ackermann, Erik Walendy +5
We report thermal expansion and heat capacity studies on LiFeSiO single crystals which enable us to investigate the critical behavior in the magnetically quasi-two-dimensio…
High-resolution valence band RIXS at the actinide M-edges
Martin Sundermann, Henrik Hahn, Denise S. Christovam +6
Understanding the electronic structure of actinide materials is crucial for both fundamental research and nuclear applications. The partially filled 5f shells exhibit complex behav…
Polarization dependency in Resonant Inelastic X-Ray Scattering
Michelangelo Tagliavini, Fabian Wenzel, Maurits W. Haverkort
Resonant Inelastic X-Ray Scattering (RIXS) is a well-established tool for probing excitations in a wide range of materials. The measured spectra strongly depend on the scattering g…
