Bosonization and correlators of the one-dimensional Hubbard model
A. A. Ovchinnikov
We present simple derivation of the Luttinger liquid relation for the 1D Hubbard model both for finite and in the limit. We describe the simple solution of the Hubba…
Two-dimensional tunnel bifurcations with dissipation
A. K. Aringazin, Yu. Dahnovsky, V. D. Krevchik +4
Two-particle tunneling in synchronous and asynchronous regimes is studied in the framework of dissipative quantum tunneling. We show that the use of the proposed model is justified…
The antiferromagnetic Ising chain in a mixed transverse and longitudinal magnetic field
A. A. Ovchinnikov, D. V. Dmitriev, V. Ya. Krivnov +1
We have studied the antiferromagnetic Ising chain in a transverse magnetic field and uniform longitudinal field . Using the density matrix renormalization group calc…
Influence of spin structures and nesting on Fermi surface and a pseudogap anisotropy in t-t'-U Hubbard model
A A Ovchinnikov, M Ya Ovchinnikova
Influence of two type of spin structures on the form of the Fermi surface (FS) and a photoemission intensity map is studied for t-t'-U Hubbard model. Mean field calculations are do…
Two-dimensional tunnel correlations with dissipation
A. K. Aringazin, Yu. Dahnovsky, V. D. Krevchik +3
Tunneling of two particles in synchronous and asynchronous regimes is studied in the framework of dissipative quantum tunneling. The critical temperature T_c corresponding to a bif…
Coexisting superconducting and spiral spin orders: models of ruthenate
A. A. Ovchinnikov, M. Ya. Ovchinnikova
Influence of a spiral spin structure on the superconducting (SC) pairing in the most probable active band of is studied in the mean field approximation. Such struct…
