Dynamical mean-field theory of active, self-interacting heteropolymers
Andriy Goychuk
Analytical theories of polymer dynamics typically focus on the linear response around some steady state obtained via perturbative calculations. The present study derives a dynamica…
Active fluctuations induce buckling of living surfaces
Matteo Ciarchi, Andriy Goychuk, Erwin Frey
Active tissues exhibit tension fluctuations that are correlated in space and time. We study a minimal overdamped surface model in which such fluctuations enter as a zero-mean, mult…
Externally driven condensates show translation-induced polarization, directed coalescence, and anomalous diffusion in viscoelastic media
Andriy Goychuk
Phase separation into compositionally and physically distinct domains is ubiquitous in (non)living matter ranging from alloys and emulsions to biomolecular condensates in cells. Th…
Delayed excitations induce polymer looping and coherent motion
Andriy Goychuk, Deepti Kannan, Mehran Kardar
We consider inhomogeneous polymers driven by energy-consuming active processes which encode temporal patterns of athermal kicks. We find that such temporal excitation programs, pro…
Self-consistent sharp interface theory of active condensate dynamics
Andriy Goychuk, Leonardo Demarchi, Ivan Maryshev +1
Biomolecular condensates help organize the cell cytoplasm and nucleoplasm into spatial compartments with different chemical compositions. A key feature of such compositional patter…
Hidden nonreciprocity as a stabilizing effective potential in active matter
Matthew Du, Andriy Goychuk, Suriyanarayanan Vaikuntanathan
Nonreciprocal interactions are known to produce distinctive dynamics in active matter. To shed light on how the stationary state of such systems is affected by breaking reciprocity…
Enzyme-enriched condensates show self-propulsion, positioning, and coexistence
Leonardo Demarchi, Andriy Goychuk, Ivan Maryshev +1
Enzyme-enriched condensates can organize the spatial distribution of their substrates by catalyzing non-equilibrium reactions. Conversely, an inhomogeneous substrate distribution i…
Geometry-induced patterns through mechanochemical coupling
Laeschkir Würthner, Andriy Goychuk, Erwin Frey
Intracellular protein patterns regulate a variety of vital cellular processes such as cell division and motility, which often involve dynamic changes of cell shape. These changes i…
Protein recruitment through indirect mechanochemical interactions
Andriy Goychuk, Erwin Frey
Some of the key proteins essential for important cellular processes are capable of recruiting other proteins from the cytosol to phospholipid membranes. The physical basis for this…
Morphology and Motility of Cells on Soft Substrates
Andriy Goychuk, David B. Brückner, Andrew W. Holle +3
Recent experiments suggest that the interplay between cells and the mechanics of their substrate gives rise to a diversity of morphological and migrational behaviors. Here, we deve…
Stochastic Wilson-Cowan models of neuronal network dynamics with memory and delay
Igor Goychuk, Andriy Goychuk
We consider a simple Markovian class of the stochastic Wilson-Cowan type models of neuronal network dynamics, which incorporates stochastic delay caused by the existence of a refra…
