A Two Band Model for Superconductivity: Probing Interband Pair Formation
We propose a two band model for superconductivity. It turns out that the simplest nontrivial case considers solely interband scattering, and both bands can be modeled as symmetric (around the Fermi level) and flat, thus each band is completely characterized by its half-band width Wn (n=1,2). A useful dimensionless parameter is δ, proportional to W2−W1. The case δ = 0 retrieves the conventional ...
متن کاملTesting V3Si for two-band superconductivity
Is V3Si a two-band or a single-band superconductor? Everyone who searches the literature for this question will find conflicting answers, for V3Si was claimed to be a perfect example of two-band and claimed to be a perfect example of single-band superconductivity. In this paper we intend to clarify the situation by presenting new experimental facts acquired from the magnetic properties of a V3S...
متن کاملDefinitive experimental evidence for two-band superconductivity in MgB2.
The superconducting-gap of MgB2 has been studied by high-resolution angle-resolved photoemission spectroscopy. The results show that superconducting gaps with values of 5.5 and 2.2 meV open on the sigma band and the pi band, respectively, but both the gaps close at the bulk transition temperature, providing a definitive experimental evidence for the two-band superconductivity with strong interb...
متن کاملQuantum Monte Carlo evidence for superconductivity in the three-band hubbard Model in Two Dimensions.
A possibility of the electronic origin of the high-temperature superconductivity in cuprates is probed with the quantum Monte Carlo method by revisiting the three-band Hubbard model comprising Cu3dx2−y2 and O2pσ orbitals. The dx2−y2 pairing correlation is found to turn into an increasing function of the repulsion Ud within the d orbitals or the d-p level off-set ∆ε, where the correlation grows ...
متن کاملA two stage model for Cell Formation Problem (CFP) considering the inter-cellular movements by AGVs
This paper addresses to the Cell Formation Problem (CFP) in which Automated Guided Vehicles (AGVs) have been employed to transfer the jobs which may need to visit one or more cells. Because of added constraints to problem such as AGVs’ conflict and excessive cessation on one place, it is possible that AGVs select the different paths from one cell to another over the time. This means that the ti...
