Single-electron states of phosphorus-atom arrays in silicon

May 8, 2024

Author(s)

Maicol Ochoa, Keyi Liu, Michal Zielinski, Garnett W. Bryant

We characterize the single-electron energies and the wavefunction structure of arrays with two, three, and four phosphorus atoms in silicon by implementing atomistic tight-binding calculations and analyzing wavefunction overlaps to identify the single

Nagaoka Ferromagnetism in 3 * 3 Arrays and Beyond

April 5, 2024

Author(s)

Yan Li, Keyi Liu, Garnett W. Bryant

Nagaoka ferromagnetism (NF) is a long-predicted example of itinerant ferromagnetism (IF) in the Hubbard model that has been studied theoretically for many years. The condition for NF, an infinite onsite Coulomb repulsion and a single hole in a half-filled
