From the double-exchange Hamiltonian to the model: Classical spins
Eugene Kogan, Mark Auslender
From the double-exchange Hamiltonian with classical localized spins in the limit of large but finit Hund exchange coupling we obtain the model (with classical localized spins…
Distribution function of mesoscopic hopping conductance
Liqun He, Eugene Kogan, Moshe Kaveh +2
We study by computer simulation distribution functions (DF) of mesoscopic hopping conductance. The DFs obtained for one-dimensional systems were found to be quite close to the pred…
Anderson localization due to spin disorder: a driving force of temperature-dependent metal-semiconductor transition in colossal-magnetoresistance materials
Eugene Kogan, Mark Auslender
We study temperature induced metal-insulator transition in doped ferromagnetic semiconductors, described by s-d exchange model. The transition is a result of the mobility edge move…
Statistics of radiation in a disordered medium: from ballistic to diffusive regime
Eugene Kogan, Moshe Kaveh
The distribution function for the intensity of radiation propagating in a random medium is analyzed for arbitrary multiplicity of scattering (for arbitrary relation between the dis…
