Novel =3/2 Metallic Phase and Unconventional Superconductivity in GaTaSe
Min Yong Jeong, Seo Hyoung Chang, Hyeong Jun Lee +10
By means of density functional theory plus dynamical mean-field theory (DFT+DMFT) calculations and resonant inelastic x-ray scattering (RIXS) experiments, we investigate the high-p…
Orbital isotropy of magnetic fluctuations in correlated electron materials induced by Hund's exchange coupling
Evgeny A. Stepanov, Yusuke Nomura, Alexander I. Lichtenstein +1
Characterizing non-local magnetic fluctuations in materials with strong electronic Coulomb interactions remains one of the major outstanding challenges of modern condensed matter t…
Tracking the Footprints of Spin Fluctuations: A MultiMethod, MultiMessenger Study of the Two-Dimensional Hubbard Model
Thomas Schäfer, Nils Wentzell, Fedor Šimkovic +23
The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling…
Intrinsically weak magnetic anisotropy of cerium in potential hard-magnetic intermetallics
Anna Galler, Semih Ener, Fernando Maccari +5
Cerium-based intermetallics are currently attracting much interest as a possible alternative to existing high-performance magnets containing scarce heavy rare-earth elements. Howev…
Anisotropy of electronic correlations: On the applicability of local theories to layered materials
Benjamin Klebel, Thomas Schäfer, Alessandro Toschi +1
Besides the chemical constituents, it is the lattice geometry that controls the most important material properties. In many interesting compounds, the arrangement of elements leads…
Resonant inelastic x-ray scattering study of doping and temperature dependence of low-energy excitations in LaSrVO
Kari Ruotsalainen, Matteo Gatti, James M. Ablett +5
We present a temperature and doping dependent resonant inelastic X-ray scattering experiment at the V L and O K edges in LaSrVO for and . This…
