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…
Two-strain competition in quasi-neutral stochastic disease dynamics
Oleg Kogan, Michael Khasin, Baruch Meerson +2
We develop a new perturbation method for studying quasi-neutral competition in a broad class of stochastic competition models, and apply it to the analysis of fixation of competing…
Onset of Singularities in the Pattern of Fluctuational Paths of a Nonequilibrium System
Oleg Kogan
Fluctuations in systems away from thermal equilibrium have features that have no analog in equilibrium systems. One of such features concerns large rare excursions far from the sta…
Universality in the one-dimensional chain of phase-coupled oscillators
Tony E. Lee, G. Refael, M. C. Cross +2
We apply a recently developed renormalization group (RG) method to study synchronization in a one-dimensional chain of phase-coupled oscillators in the regime of weak randomness. T…
Scaling crossovers in activated escape of nonequilibrium systems: a resonantly driven oscillator
Oleg Kogan
The rate of metastable decay in nonequilibrium systems is expected to display scaling behavior: i.e., the logarithm of the decay rate should scale as a power of the distance to a b…
