Critical dynamics of the superfluid phase transition: Multiloop calculation of the microscopic model.

Results and method of a three-loop renormalization-group calculation in the model of a Bose gas with a local density-density interaction in the formalism of time-dependent Green functions at finite temperature are presented. The results provide support to the recent conjecture [J. Honkonen, M.

Fixed-dimension renormalization group analysis of conserved surface roughening.

Conserved surface roughening represents a special case of interface dynamics where the total height of the interface is conserved. Recently, it was suggested [Caballero et al., Phys.

Comment on "Turbulent compressible fluid: Renormalization group analysis, scaling regimes, and anomalous scaling of advected scalar fields".

Recently, asymptotic scaling behavior of the compressible randomly forced Navier-Stokes equation has been analyzed with the use of field-theoretic renormalization group near four dimensions [Phys. Rev. E 95, 033120 (2017)PREHBM2470-004510.

Universality in incompressible active fluid: Effect of nonlocal shear stress.

Phase transitions in active fluids attracted significant attention within the last decades. Recent results show [L. Chen et al.

Influence of turbulent mixing on critical behavior of directed percolation process: Effect of compressibility.

Universal behavior is a typical emergent feature of critical systems. A paramount model of the nonequilibrium critical behavior is the directed bond percolation process that exhibits an active-to-absorbing state phase transition in the vicinity of a percolation threshold. Fluctuations of the ambient environment might affect or destroy the universality properties completely.
