The relativistic 5f electronic structure of delocalized -U and localized -Pu from the self consistent vertex corrected GW approach and X-ray Emission Spectroscopy
A. L. Kutepov, J. G. Tobin, S. -W. Yu +8
The recently developed self-consistent vertex corrected GW method is used to calculate the 5f electronic structure in delocalized -U and localized -Pu, each of which is confi…
Generation of Intense Phase-Stable Femtosecond Hard X-ray Pulse Pairs
Yu Zhang, Thomas Kroll, Clemens Weninger +24
Coherent nonlinear spectroscopies and imaging in the X-ray domain provide direct insight into the coupled motions of electrons and nuclei with resolution on the electronic length a…
Hammerhead, an ultrahigh resolution ePix camera for wavelength-dispersive spectrometers
G. Blaj, D. Bhogadi, C. -E. Chang +7
Wavelength-dispersive spectrometers (WDS) are often used in synchrotron and FEL applications where high energy resolution (in the order of eV) is important. Increasing WDS energy r…
Effective Hamiltonian for transition-metal compounds. Application to Na_xCoO_2
A. A. Aligia, T. Kroll
We describe a simple scheme to construct a low-energy effective Hamiltonian H_eff for highly correlated systems containing non-metals like O, P or As (O in what follows) and a tran…
On the electronic structure of electron doped LaOFeAs as seen by X-ray absorption spectroscopy
T. Kroll, S. Bonhommeau, T. Kachel +14
We investigated the recently found superconductor LaO_{1-x}F_xFeAs by X-ray absorption spectroscopy (XAS). From a comparison of the O K-edge with LDA calculations we find good agre…
Electronic structure and Fermi surface tolopogy of NaCoO
A. Bourgeois, A. A. Aligia, T. Kroll +1
We construct an effective Hamiltonian for the motion of T2g highly correlated states in NaxCoO2. We solve exactly a multiband model in a CoO6 cluster with electronic occupation cor…
