Query: Reaction-Diffusion dynamics in presence of active barrier: Pinhole sink   In this article, we give a semi-analytic expression for survival probability
when particles are diffusing in an active potential well. There is no analytic
solution available in the literature, due to the requirement of inverse Laplace
transform of the propagator, when a sink is placed at the uphill of the
parabolic potential even in case of the localized sink. We also explain some of
the physical aspects by using our solution.
