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…
