Formation of Hubbard-like bands as a fingerprint of strong electron-electron interactions in FeSe
Matthew D. Watson, Steffen Backes, Amir A. Haghighirad +4
We use angle-resolved photo-emission spectroscopy (ARPES) to explore the electronic structure of single crystals of FeSe over a wide range of binding energies and study the effects…
Origin of the superconducting state in the collapsed tetragonal phase of KFe2As2
Daniel Guterding, Steffen Backes, Harald O. Jeschke +1
Recently, KFeAs was shown to exhibit a structural phase transition from a tetragonal to a collapsed tetragonal phase under applied pressure of about . Surp…
Correlation effects in the tetragonal and collapsed tetragonal phase of CaFe2As2
Jean Diehl, Steffen Backes, Daniel Guterding +2
We investigate the role of correlations in the tetragonal and collapsed tetragonal phases of CaFe2As2 by performing charge self-consistent DFT+DMFT (density functional theory combi…
Electronic structure and de Haas-van Alphen frequencies in KFe2As2 within LDA+DMFT
Steffen Backes, Daniel Guterding, Harald O. Jeschke +1
Recent density functional theory (DFT) calculations for KFe2As2 have shown to be insufficient to satisfactorily describe angle-resolved photoemission (ARPES) measurements as well a…
