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…
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…
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…
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…
