Cumulant-based calculations of the correlation energy in a molecule
A. K. Zhuravlev
The problem of constructing a guaranteed convergent sequence of corrections to the Hartree--Fock ground state energy of a molecule without storing the many-electron wave function i…
One- and two-channel Kondo model with logarithmic Van Hove singularity: a numerical renormalization group solution
A. K. Zhuravlev, A. O. Anokhin, V. Yu. Irkhin
Simple scaling consideration and NRG solution of the one- and two-channel Kondo model in the presence of a logarithmic Van Hove singularity at the Fermi level is given. The tempera…
Cumulant -expansion for strongly correlated fermions
A. K. Zhuravlev
A systematic nonperturbative scheme is implemented to calculate the ground state energy for a wide class of strongly correlated fermion models. The scheme includes: (a) method of a…
Ising model on a square lattice with second-neighbor and third-neighbor interactions
F. A. Kassan-Ogly, A. K. Murtazaev, A. K. Zhuravlev +2
We studied the phase transitions and magnetic properties of the Ising model on a square lattice by the replica Monte Carlo method and by the method of transfer-matrix, the maximum…
The Kondo effect in the presence of Van Hove singularities: A numerical renormalization group study
A. K. Zhuravlev, V. Yu. Irkhin
A numerical renormalization group (NRG) investigation of the one-centre Kondo problem is performed for the square lattice with account of logarithmic Van Hove singularities…
Negative Impurity Magnetic Susceptibility and Heat Capacity in a Kondo Model with Narrow Peaks in the Local Density of Electron States
A. K. Zhuravlev
Temperature dependencies of the impurity magnetic susceptibility, entropy, and heat capacity have been obtained by the method of numerical renormalization group and exact diagonali…
