Aging in a two-dimensional swarmalator crystal with delayed interactions
Chanin Kumpeerakij, Thiparat Chotibut, Oleg Kogan
Time delay can have a significant impact on the properties of collective organization of active matter. In the previous paper [1], we discussed delay-induced breathing in a system…
Tunable intracellular transport on converging microtubule morphologies
Niranjan Sarpangala, Brooke Randell, Ajay Gopinathan +1
A common type of cytoskeletal morphology involves multiple converging microbutubules with their minus ends collected and stabilized by a microtubule organizing center (MTOC) in the…
Swarmalators with delayed interactions
Nicholas Blum, Andre Li, Kevin O'Keeffe +1
We investigate the effects of delayed interactions in a population of ``swarmalators", generalizations of phase oscillators that both synchronize in time and swarm through space. W…
Path-dependent course of epidemic: are two phases of quarantine better than one?
Varun Nimmagadda, Oleg Kogan, Evgeniy Khain
The importance of a strict quarantine has been widely debated during the COVID-19 epidemic even from the purely epidemiological point of view. One argument against strict lockdown…
FKPP dynamics mediated by a parent field with a delay
Steffanie Stanley, Oleg Kogan
We examine a modification of the Fisher-Kolmogorov-Petrovsky-Piskunov (FKPP) process in which the diffusing substance requires a parent density field for reproduction. A biological…
Fragility of reaction-diffusion models to competing advective processes
Oleg Kogan, Kevin O'Keeffe, Christopher R. Myers
We study the coupling of a Fisher-Kolmogorov-Petrovsky-Piskunov (FKPP) equation to a separate, advection-only transport process. We find that the front dynamics can be described by…
