Research reports from Massey University provide new insights into physics

  2008 SEP 15 - (VerticalNews.com) -- "We have analyzed theoretically the Zeeman splitting of hole-quantum-wire subband edges," scientists writing in the journal Physical Review B report.

  "As is typical for any bound state, their g factor depends on both an intrinsic g factor of the material and an additional contribution arising from a finite bound-state orbital angular momentum. We discuss the quantum-confinement-induced interplay between bulk-material and orbital effects, which is nontrivial due to the presence of strong spin-orbit coupling," wrote D. Csontos and colleagues, Massey University.

  The researchers concluded: "A compact analytical formula is provided that elucidates this interplay and can be useful for predicting Zeeman splitting in generic hole-wire geometries."

  Csontos and colleagues published their study in Physical Review B (Lande-like formula for the g factors of hole-nanowire subband edges. Physical Review B, 2008;78(3):3307).
