Perturbation study of the conductance through a finite Hubbard chain
نویسنده
چکیده
The dc conductance through a Hubbard chain of size N (=1,2, 3, . . . ) connected to noninteracting leads is studied at T = 0 in an electron-hole symmetric case using a perturbation theory in U . The result shows a typical even-odd property corresponding to a Kondo or Mott-Hubbard physics.

متن کاملQuasi-particle description for the transport through a small interacting system
We study effects of electron correlation on the transport through a small interacting system connected to reservoirs using an effective Hamiltonian which describes the free quasi-particles of a Fermi liquid. The effective Hamiltonian is defined microscopically with the value of the self-energy at ω = 0. Specifically, we apply the method to a Hubbard chain of finite size N (= 1, 2, 3, . . .), an...
متن کاملTransport through a finite Hubbard chain connected to reservoirs
The dc conductance, gN , through a finite Hubbard chain of size N (= 1, 2, 3, . . .) connected to reservoirs is studied at T = 0 in an electron-hole symmetric case. We calculate a spatial dependence of the self energy analytically at ω = 0 within the second order in U , and obtain an inter-site Green’s function GN1, from which gN can be determined, via the Dyson equation. The results depend str...

The transport of charge and spin at finite energies is studied for the Hubbard chain in a magnetic field by means of the pseudoparticle perturbation theory. In the general case, this involves the solution of an infinite set of Bethe-ansatz equations with a flux. Our results refer to all densities and magnetizations. We express the charge and the spin-diffusion currents in terms of elementary cu...
متن کاملEffects of disorder onconductance through small interacting systems
We study the effects of disorders on the transport through small interacting systems based on a two-dimensional Hubbard cluster of finite size connected to two noninteracting leads. This system can be regarded as a model for the superlattice of quantum dots or atomic network of the nanometer size. We calculate the conductance at T = 0 using the order U self-energy in an electron-hole symmetric ...
