On the existence of Cooper pairs in the Hubbard Model
Valentin Voroshilov
TL;DR
This paper demonstrates the existence of Cooper pairs formed by strongly interacting quasiparticles in the Hubbard model using a novel canonical transformation, advancing understanding of pairing mechanisms in strongly correlated systems.
Contribution
Introduces a new canonical transformation that proves the existence of Cooper pairs in the Hubbard model at half filling.
Findings
Cooper pairs are formed by strongly interacting quasiparticles.
The canonical transformation reveals pairing mechanisms in the Hubbard model.
Supports the relevance of quasiparticle interactions in high-temperature superconductivity.
Abstract
By means of a new canonical transformation for the one-band Hubbard model at half filling we show the existence of Cooper pairs formed by strongly interacting quasiparticles.
