Abstract
The probability that a randomly accelerated particle in two dimensions has not yet left a simply connected domain after a time t decays as e-E0t for long times. The same quantity E0 also determines the confinement free energy per unit length Δf = kBT E0 of a semiflexible polymer in a narrow cylindrical pore with cross section . From simulations of a randomly accelerated particle we estimate the universal amplitude of Δf for both circular and rectangular cross sections.Keywords
