Collective motion in a sheet of microswimmers
Dóra Bárdfalvy, Viktor Škultéty, Cesare Nardini +2
Self-propelled micron-size particles suspended in a fluid, like bacteria or synthetic microswimmers, are strongly non-equilibrium systems where particle motility breaks the microsc…
Universal properties of active membranes
Francesco Cagnetta, Viktor Skultety, Martin R. Evans +1
We put forward a general field theory for membranes with embedded activators and analyse their critical properties using renormalization group techniques. Depending on the membrane…
A renormalization group study of the dynamics of active membranes: universality classes and scaling laws
Francesco Cagnetta, Viktor Skultety, Martin R. Evans +1
Motivated by experimental observations of patterning at the leading edge of motile eukaryotic cells, we introduce a general model for the dynamics of nearly-flat fluid membranes dr…
Fixed Renormalization Group Analysis of Conserved Surface Roughening
V. Skultety, J. Honkonen
Conserved surface roughening represents a special case of interface dynamics where the total height of the interface is conserved. Recently, it was suggested [F. Caballero et al.,…
Universality in Incompressible Active Fluid: Effect of Non-local Shear Stress
Viktor Skultety, Sarlota Birnsteinova, Tomas Lucivjansky +1
Phase transitions in active fluids attracted significant attention within the last decades. Recent results show [L. Chen et al., New J. Phys. 17, 042002 (2015)] that an order-disor…
Swimming suppresses correlations in dilute suspensions of pusher microorganisms
Viktor Škultéty, Cesare Nardini, Joakim Stenhammar +2
Active matter exhibits various forms of non-equilibrium states in the absence of external forcing, including macroscopic steady-state currents. Such states are often too complex to…
A note on forces exerted by a Stokeslet on confining boundaries
Viktor Škultéty, Alexander Morozov
We consider a Stokeslet applied to a viscous fluid next to an infinite, flat wall, or in-between two parallel walls. We calculate the forces exerted by the resulting flow on the co…
Passive advection of percolation process: Two-loop approximation
Š. Birnšteinová, M. Hnatič, T. Lučivjanský +2
The paradigmatic model of the directed percolation process is studied near its second order phase transition between an absorbing and an active state. The model is first expressed…
Stochastic Navier-Stokes equation for a compressible fluid: two-loop approximation
M. Hnatič, N. M. Gulitskiy, T. Lučivjanský +2
A model of fully developed turbulence of a compressible fluid is briefly reviewed. It is assumed that fluid dynamics is governed by a stochastic version of Navier-Stokes equation.…
Influence of turbulent mixing on critical behavior of directed percolation process : effect of compressibility
J. Honkonen, T. Lučivjanský, V. Škultéty
Universal behavior is a typical emergent feature of critical systems. A paramount model of the non-equilibrium critical behavior is the directed bond percolation process that exhib…
