Superconducting Fluctuations in a Multi-Band 1D Hubbard Model
نویسنده
چکیده
A renormalization-group and bosonization approach for a multi-band Hubbard Hamiltonian in one dimension is described. Based on the limit of many bands, it is argued that this Hamiltonian with bare repulsive electron-electron interactions is scaled under specific conditions to a model in which superconducting fluctuations dominate.

Charge and Phase Fluctuations in Attractive Hubbard Model
Using the negative U Hubbard model we analyze normal state properties of a superconductor. In this model there exists a characteristic pairing temperature TP above a superconducting critical temperature. Below TP electrons start to form incoherent pairs. The fluctuations in charge and phase are precursors of charge density wave and superconductivity phases depending on band filling. They lead n...
متن کاملA Common Thread *
The structures, the phase diagrams, and the appearance of a neutron resonance in the superconducting state provide phenomenological evidence which relate the heavy fermion, cuprate and Fe superconductors. Singleand multi-band Hubbard models have been found to describe a number of the observed properties of these materials so that it is reasonable to examine the origin of the pairing interaction...

A microscopic theory of superconducting pairing within the Hubbard model is discussed. A Dyson equation for the matrix thermodynamic Green function in the Nambu representation for Hubbard operators is derived by applying the Mori-type projection technique for the equation of motion method. The self-energy is calculated in the noncrossing approximation for electron scattering on spin and charge ...

The mean field Green function solution of the two-band singlet-hole Hubbard model for high-Tc superconductivity in cuprates (Plakida, N.M. et al., Phys. Rev. B51, 16599 (1995), JETP 97, 331 (2003)) involves expressions of higher order correlation functions describing respectively the singlet hopping and the superconducting pairing. Rigorous derivation of their values is reported based on the fi...
متن کاملFluxoid fluctuations in mesoscopic superconducting rings
Superconducting rings represent an ideal system for studying phase coherence in one dimension. We study the temperature dependence of the magnetic susceptibility of superconducting rings with a scanning superconducting quantum interference device. The physical parameters of the rings were designed to reduce the superconducting phase stiffness. We observe a suppression of the susceptibility sign...
