We study possible quantum states of two correlated electrons in a twodimensional periodic potential and find a metastable energy band of electron pairs between the two lowest singleelectron bands. These metastable states ...

Inspite of the direct evidence for Cooper pairing in the cuprates as in conventional superconductors, the pairing symmetry in the cuprate superconductors is still considered to be a controversial and a highly debatable ...

The classical frame potential in a finite dimensional Hilbert space has been introduced by Benedetto and Fickus, who showed that all finite unit-norm tight frames can be characterized as the minimizers of this energy ...

The IPPP-CLOPPA method is applied to investigate the influence of a methyl group on the energy of the hydrogen bonds and the potential energy curve of the bridge protons in model compounds, which mimic the methylated and ...

For the last decade, elliptic curve cryptography has gained increasing interest in industry and in the academic community. This is especially due to the high level of security it provides with relatively small keys and to ...

The objective of this work was to relate dynamic rheological data to the pair interaction potential between casein micelles (CM) in concentrated systems. The elastic moduli at high frequencies (G∞ ′) were obtained by fitting ...
