How Do You Want That Insulator?
Gregory A. Fiete
A normal insulator is turned into an exotic topological insulator by tuning its elemental composition.
Disorder, spin-orbit, and interaction effects in dilute
Gregory A. Fiete, Gergely Zarand, Kedar Damle +1
We derive an effective Hamiltonian for in the dilute limit, where can be described in terms of spin …
Disorder induced local density of states oscillations on narrow Ag(111) terraces
Karina Morgenstern, Karl-Heinz Rieder, Gregory A. Fiete
The local density of states of Ag(111) has been probed in detail on disordered terraces of varying width by dI/dV-mapping with a scanning tunneling microscope at low temperatures.…
Positional Disorder, Spin-Orbit Coupling and Frustration in GaMnAs
Gregory A. Fiete, Gergely Zarand, Boldizsar Janko +2
We study the magnetic properties of metallic GaMnAs. We calculate the effective RKKY interaction between Mn spins using several realistic models for the valence band structure of G…
Effective Hamiltonian for Ga_{1-x}Mn_xAs in the Dilute Limit
Gregory A. Fiete, Gergely Zarand, Kedar Damle
We derive an effective Hamiltonian for in the dilute limit, where can be described in terms of spin …
