Nonlinear susceptibilities of a weakly-disordered uniaxial ferromagnet in the critical region
D. V. Pakhnin, A. I. Sokolov, B. N. Shalaev
For the three-dimensional random Ising model, the effective sextic coupling constant v_6 and the nonlinear susceptibilities of the fourth (chi_4) and sixth (chi_6) orders are calcu…
Kramers-Wannier symmetry and strong-weak-coupling duality in the two-dimensional field model
Boris N. Shalaev
It is found that the exact beta-function of the continuous 2D model possesses two types of dual symmetries, these being the Kramers-Wannier (KW) duality symmetry an…
Schrodinger equation approach to non-linear -models in the large N-limit
Boris N. Shalaev
Non-linear d-dimensional vector -models are studied in the large N-limit. It is found that a two-point correlation function obeys a standard Schrodinger equation for a free quan…
Duality symmetry, strong coupling expansion and universal critical amplitudes in two-dimensional Φ^{4} field models
Giancarlo Jug, Boris N. Shalaev
We show that the exact beta-function β(g) in the continuous 2D gΦ^{4} model possesses the Kramers-Wannier duality symmetry. The duality symmetry transformation \tilde{g}=d(g) such…
Low-temperature renormalization group study of uniformly frustrated models for type-II superconductors
Giancarlo Jug, Boris N. Shalaev
We study phase transitions in uniformly frustrated SU(N)-symmetric -dimensional lattice models describing type-II superconductors near the upper critical magnetic field $H_{…
Five-loop \sqrtε-expansions for random Ising model and marginal spin dimensionality for cubic systems
B. N. Shalaev, S. A. Antonenko, A. I. Sokolov
The \sqrtε-expansions for critical exponents of the weakly-disordered Ising model are calculated up to the five-loop order and found to possess coefficients with irregular signs an…
