Distribution of currents in a system of active particles with biased hops and Ising interactions
Evgeniy Khain, Shriram Ramesh, Vladimir Chernyak
We consider an ensemble of particles performing a biased random walk on a two-dimensional lattice. Due to the adhesion between particles (nearest-neighbor Ising interactions), the…
Spatial spread of infection: transitions between pulled and pushed fronts
Evgeniy Khain, Rohan Sukumar
We consider the spatial spread of epidemic into an unstable, healthy state. When the transmission rate depends on the fraction of infected, the propagating pulse of infection can b…
Speed fluctuations of a stochastic Huxley-Zel'dovich front
Evgeniy Khain, Baruch Meerson, Pavel V. Sasorov
The empirical speed of travelling reaction-diffusion fronts fluctuates due to the intrinsic shot noise of the reactions and diffusion. Here we study the long-time front speed fluct…
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…
Velocity fluctuations of stochastic reaction fronts propagating into an unstable state: strongly pushed fronts
Evgeniy Khain, Baruch Meerson, Pavel Sasorov
The empirical velocity of a reaction-diffusion front, propagating into an unstable state, fluctuates because of the shot noises of the reactions and diffusion. Under certain condit…
Two-level modeling of quarantine
Evgeniy Khain
Continuum models of epidemics do not take into account the underlying microscopic network structure of social connections. This drawback becomes extreme during quarantine when most…
