Evidence for an Obstruction to Perturbative Renormalization Group in Stochastic Turbulence
L. Ts. Adzhemyan, D. A. Davletbaeva, D. A. Evdokimov +1
We examine whether the perturbative renormalization group (RG) regime of stochastic turbulence can be continued from small to the physical value $\varepsilon_{\mathrm…

Dynamic critical exponent of the Yang--Lee edge singularity at three loops
Loran Ts. Adzhemyan, Diana A. Davletbaeva, Daniil A. Evdokimov +1
We compute the dynamic critical exponent of the Yang--Lee edge singularity in relaxational dynamics using perturbative renormalization-group methods to the three-loop order. Th…

Multiloop calculations with parametric integration in critical dynamics: the four-loop analytic study of model A of theory
Loran Ts. Adzhemyan, Diana A. Davletbaeva, Daniil A. Evdokimov +1
We perform an analytical four loop calculation of exponent in model A of critical dynamics in dimensions. This is the first time such a large order of pertur…
