Phys. Rev. E 55, 4005–4011 (1997)Effect of partially reflecting boundary conditions on the decay of metastable rest states in an activator-inhibitor systemReceived 23 May 1996; published in the issue dated April 1997 We study the effect of the boundary conditions on the spontaneous nucleation and evaporation of excited domains in the bistable regime of an activator-inhibitor stochastic system. In such a regime a quasivariational approximation can be used to obtain the stationary distribution. The nucleation and evaporation rates of the resulting nonuniform structures are investigated using a piecewise-linear dynamics to obtain analytical results. © 1997 The American Physical Society URL:
