Diagonalisation method in the asymptotical theory for solutions of systems of ODE
A. A. Vladimirov
The question about asymptotical behaviour of solutions for the system for big values of the parameter is considered. An approach to the reduction of a…
Magnetic order and spin excitations in the Kitaev--Heisenberg model on the honeycomb lattice
A. A. Vladimirov, D. Ihle, N. M. Plakida
We consider the quasi-two-dimensional pseudo-spin-1/2 Kitaev - Heisenberg model proposed for A2IrO3 (A=Li, Na) compounds. The spin-wave excitation spectrum, the sublattice magnetiz…
Magnetic order and spin excitations in layered Heisenberg antiferromagnets with compass-model anisotropies
A. A. Vladimirov, D. Ihle, N. M. Plakida
The spin-wave excitation spectrum, the magnetization, and the Néel temperature for the quasi-two-dimensional spin-1/2 antiferromagnetic Heisenberg model with compass-model interact…
Three-loop calculations in non-Abelian gauge theories
O. V. Tarasov, A. A. Vladimirov
A detailed description of the method for analytical evaluation of the three-loop contributions to renormalization group functions is presented. This method is employed to calculate…
Optical and dc conductivities of cuprates: Spin-fluctuation scattering in the t-J model
A. A. Vladimirov, D. Ihle, N. M. Plakida
A microscopic theory of the electrical conductivity within the t-J model is developed. An exact representation for is obtained using the memory-function technique for…
Leading infrared logarithms for sigma-model with fields on arbitrary Riemann manifold
M. V. Polyakov, A. A. Vladimirov
We derive non-linear recursion equation for the leading infrared logarithms (LL) in four dimensional sigma-model with fields on an arbitrary Riemann manifold. The derived equation…
