Instantons for Dynamic Models from B to H
Juha Honkonen, M. V. Komarova, M. Yu. Nalimov
Instanton analysis is applied to models B--H of critical dynamics. It is shown that the static instanton of the massless model determines the large-order asymptotes of the…
Two-loop calculation of the turbulent Prandtl number
L. Ts. Adzhemyan, J. Honkonen, T. L. Kim +1
The turbulent Prandtl number has been calculated in the two-loop approximation of the $\eps$ expansion of the stochastic theory of turbulence. The strikingly small value obtained f…
Nonrelativistic QED approach to the bound-electron g factor
K. Pachucki, U. D. Jentschura, V. A. Yerokhin
Within a systematic approach based on nonrelativistic quantum electrodynamics (NRQED), we derive the one-loop self-energy correction of order alpha (Zalpha)^4 to the bound-electron…
Generalized Darboux Transform in the Ishimori magnet model on the background of spiral structures
E. Sh. Gutshabash
The integration procedure based on the the generalized Darboux transform is suggested for the Ishimori magnet model. Exact solutions are constructed for the model of background of…
Interelectronic-interaction effect on the transition probability in high-Z He-like ions
Paul Indelicato, V. M. Shabaev, A. V. Volotka
The interelectronic-interaction effect on the transition probabilities in high-Z He-like ions is investigated within a systematic quantum electrodynamic approach. The calculation f…
An improved $\eps$ expansion for three-dimensional turbulence: two-loop renormalization near two dimensions
L. Ts. Adzhemyan, J. Honkonen, M. V. Kompaniets +1
An improved $\eps$ expansion in the -dimensional () stochastic theory of turbulence is constructed at two-loop order which incorporates the effect of pole singularities a…
