Flat-band hybridization between and states near the Fermi energy of SmCoIn
David W. Tam, Nicola Colonna, Fatima Alarab +4
We present high-quality angle-resolved photoemission (ARPES) and density functional theory calculations (DFT+U) of SmCoIn. We find broad agreement with previously published stu…
Charge fluctuations in the intermediate-valence ground state of SmCoIn
David W. Tam, Nicola Colonna, Neeraj Kumar +9
The microscopic mechanism of heavy band formation, relevant for unconventional superconductivity in CeCoIn and other Ce-based heavy fermion materials, depends strongly on the e…
Correlation energy within exact-exchange ACFD theory: systematic development and simple approximations
Nicola Colonna, Maria Hellgren, Stefano de Gironcoli
We have calculated the correlation energy of the homogeneous electron gas (HEG) and the dissociation energy curves of molecules with covalent bonds from a novel implementation of t…
