Broken site symmetry of Fe adatoms on BiTe
Duy Nguyen, Hari Paudyal, Joseph R. Sink +2
We report a combined scanning tunneling microscopy and atomistic theoretical study of Fe adatoms on the BiTe(111) surface. Topographic imaging at ~K shows that Fe adat…
Imaging the Acceptor Wave Function Anisotropy in Silicon
Manuel Siegl, Julian Zanon, Joseph Sink +5
We present the first scanning tunneling microscopy (STM) images of hydrogenic acceptor wave functions in silicon. These acceptor states appear as square ring-like features in STM i…
Crystal fields, exchange, and dipolar interactions and noncollinear magnons of erbium oxide
Kian Maleki, Michael E. Flatté
We simulate the properties of magnons in erbium oxide, a noncollinear antiferromagnet, from an effective single-ion Hamiltonian, including exchange and long-range dipolar interacti…
Robust Edge States from Band Topology in a Damped One-dimensional Magnonic Crystal
Kwangyul Hu, Denis R. Candido, Michael E. Flatté
The presence or absence of topologically-produced edge states of a crystal are robust to disorder; their stability in the presence of decay is less clear. For topologically nontriv…
