Magnetic Order-Disorder Transitions on a 1/3 - Depleted Square Lattice
H. -M. Guo, T. Mendes-Santos, W. E. Pickett +1
Quantum Monte Carlo simulations are used to study the magnetic and transport properties of the Hubbard Model, and its strong coupling Heisenberg limit, on a one-third depleted squa…
Tuning ferromagnetic BaFe(PO) through a high Chern number topological phase
Young-Joon Song, Kyo-Hoon Ahn, W. E. Pickett +1
There is strong interest in discovering or designing wide gap Chern insulators. Here we follow a Chern insulator to trivial Mott insulator transition versus interaction strength U…
Cubic HS around 200 GPa: an atomic hydrogen superconductor stabilized by sulfur
D. A. Papaconstantopoulos, B. M. Klein, M. J. Mehl +1
The multiple scattering-based theory of Gaspari and Gyorffy for the electron-ion matrix element in close packed metals is applied to Im-3m H3S, which has been predicted by Duan {\i…
Strong interactions, narrow bands, and dominant spin-orbit coupling in Mott insulating quadruple perovskite CaCo3V4O12
H. B. Rhee, W. E. Pickett
We investigate the electronic and magnetic structures and the character and direction of spin and orbital moments of the recently synthesized quadruple perovskite cobaltovanadate C…
Unquenched orbital moment in the Mott insulating antiferromagnet KOsO4
Young-Joon Song, Kyo-Hoon Ahn, K. -W. Lee +1
Applying the correlated electronic structure method based on density functional theory plus the Hubbard interaction, we have investigated the tetragonal scheelite structure Mot…
Contrast of LiFeAs with isostructural, isoelectronic, and non-superconducting MgFeGe
H. B. Rhee, W. E. Pickett
Stoichiometric LiFeAs at ambient pressure is an 18 K superconductor while isoelectronic MgFeGe is not, despite their extremely similar electronic structures. To investigate possibl…
