Growth-Induced Transitions in Viscoelastic Matter
Valentin Slepukhin, Oskar Hallatschek
Growth is a fundamental process in living systems. Although the stress-deformation response of growing materials is often described as either purely elastic or purely viscous, many…
Barrier-Free Microhabitats: Self-Organized Seclusion in Microbial Communities
Valentin Slepukhin, Víctor Peris Yagüe, Christian Westendorf +2
Bacteria frequently colonize natural microcavities such as gut crypts, plant apoplasts, and soil pores. Recent studies have shown that the physical structure of these spaces plays…
Braiding dynamics in semiflexible filament bundles under oscillatory forcing
Valentin M. Slepukhin, Alex J. Levine
We examine the nonequilibrium production of topological defects -- braids -- in semiflexible filament bundles under cycles of compression and tension. During these cycles, the peri…
Thermal Schwinger Effect: Defect Production in Compressed Filament Bundles
Valentin M Slepukhin, Alex J Levine
We discuss the response of biopolymer filament bundles bound by transient cross linkers to compressive loading. These systems admit a mechanical instability at stresses typically b…
Microcircuit synchronization and heavy tailed synaptic weight distribution in preBötzinger Complex contribute to generation of breathing rhythm
Valentin M. Slepukhin, Sufyan Ashhad, Jack L. Feldman +1
The preBötzinger Complex, the mammalian inspiratory rhythm generator, encodes inspiratory time as motor pattern. Spike synchronization throughout this sparsely connected network ge…
Disordered biopolymer filament bundles: Topological defects and kinks
Valentin M. Slepukhin, Maximilian J. Grill, Qingda Hu +3
Bundles of stiff filaments are ubiquitous in the living world, found both in the cytoskeleton and in the extracellular medium. These bundles are typically held together by smaller…
Directed force propagation in semiflexible networks
Maximilian J. Grill, Jonathan Kernes, Valentin M. Slepukhin +2
We consider the propagation of tension along specific filament of a semiflexible filament network in response to the application of a point force using a combination of numerical s…
Dynamical phase separation on rhythmogenic neuronal networks
Mihai Bibireata, Valentin M. Slepukhin, Alex J. Levine
We explore the dynamics of the preBötzinger complex, the mammalian central pattern generator with neurons, which produces a collective metronomic signal that times th…
The conformation of a semiflexible filament in a quenched random potential
Valentin M. Slepukhin, Maximilian J. Grill, Kei W. Müller +2
Motivated by the observation of the storage of excess elastic free energy - (prestress) -- in cross linked semiflexible networks, we consider the problem of the conformational stat…
Infrared dynamics of the massive theory on de Sitter space
E. T. Akhmedov, F. K. Popov, V. M. Slepukhin
We study massive real scalar theory in the expanding Poincare patch of de Sitter space. We calculate the leading two-loop infrared contribution to the two-point function in t…
