The excitation energy spectrum for a system with electron pairs tunneling in a two-leg ladder has a doping depended gap
Valentin Voroshilov
A new model with a new Hamiltonian is offered as the means for studying properties of a system of strongly correlated electrons. Consideration of the simplest possible situation, n…
The existence of a quantum phase transition in a Hubbard model on a square lattice
Valentin Voroshilov
A novel canonical transformation is offered as the mean for studying properties of a system of strongly correlated electrons. As an example of the utility of the transformation, it…
The existence of a quantum phase transition in a Hubbard model on a quasi-one-dimentional two-leg ladder
Valentin Voroshilov
A canonical transformation of a new type is offered as the mean for studying properties of a system of strongly correlated electrons. As an example of the utility of the transforma…
On a possibility of effective electron attraction without "a glue"
Valentin Voroshilov
With the means of Schrodinger equation a two electron problem is considered. It is shown that electrons in a periodic potential might experience effective attraction without any me…
On Unconventional Electron Pairing In a Periodic Potential
Valentin Voroshilov
On the assumption that two electrons with the same group velocity effectively attract each other a simple model Hamiltonian is proposed to question the existence of unconventional…
On the existence of Cooper pairs in the Hubbard Model
Valentin Voroshilov
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.
