Theory of Weak Localization in Ferromagnetic (Ga,Mn)As
Ion Garate, Jairo Sinova, T. Jungwirth +1
We study quantum interference corrections to the conductivity in (Ga,Mn)As ferromagnetic semiconductors using a model with disordered valence band holes coupled to localized Mn mom…
Finite-temperature Screening and the Specific Heat of Doped Graphene Sheets
M. R. Ramezanali, M. M. Vazifeh, Reza Asgari +2
At low energies, electrons in doped graphene sheets are described by a massless Dirac fermion Hamiltonian. In this work we present a semi-analytical expression for the dynamical de…
Electronic structure of multilayer graphene
Hongki Min, A. H. MacDonald
We study the electronic structure of multilayer graphene using a -orbital continuum model with nearest-neighbor intralayer and interlayer tunneling. Using degenerate state pertu…
Chern-number spin Hamiltonians for magnetic nano-clusters by DFT methods
T. O. Strandberg, C. M. Canali, A. H. MacDonald
Combining field-theoretical methods and ab-initio calculations, we construct an effective Hamiltonian with a single giant-spin degree of freedom, capable of the describing the low-…
