Localization Bounds for an Electron Gas
Mathematical analysis of the Anderson localization has been facilitated by the use of suitable fractional moments of the Green function. Related methods permit now a readily accessible derivation of a number of physical manifestations of localization, in regimes of strong disorder, extreme energies, or weak disorder away from the unperturbed spectrum. The present work establishes on this basis ...
متن کاملLocalization of two-dimensional electron gas in LaAlO3/SrTiO3 heterostructures
We report strong localization of two-dimensional electron gas in LaAlO3/SrTiO3 epitaxial thin-film heterostructures grown on (LaAlO3)0.3-(Sr2AlTaO3)0.7 substrates by using pulsed laser deposition with in situ reflection high-energy electron diffraction. Using longitudinal and transverse magnetotransport measurements, we have determined that disorder at the interface influences the conduction be...
متن کاملLocalization Bounds for Multiparticle Systems
We consider the spectral and dynamical properties of quantum systems of n particles on the lattice Z, of arbitrary dimension, with a Hamiltonian which in addition to the kinetic term includes a random potential with iid values at the lattice sites and a finite-range interaction. Two basic parameters of the model are the strength of the disorder and the strength of the interparticle interaction....
متن کاملElectron localization and a confined electron gas in nanoporous inorganic electrides.
The nanoporous main group oxide 12CaO.7Al(2)O3 (C12A7) can be transformed from a wide-gap insulator to an electride where electrons substitute anions in cages constituting a positive frame. Our ab initio calculations of the electronic structure of this novel material give a consistent explanation of its high conductivity and optical properties. They show that the electrons confined in the inert...
متن کاملHydrodynamic equations for an electron gas in graphene
*Correspondence: [email protected] Dipartimento di Matematica e Informatica, Università di Firenze, Viale Morgagni 67/A, Firenze, 50134, Italy Abstract In this paper we review, and extend to the non-isothermal case, some results concerning the application of the maximum entropy closure technique to the derivation of hydrodynamic equations for particles with spin-orbit interaction and Ferm...
