摘要：

The probability that a randomly accelerated particle in two dimensions has not yet left a simply connected domain A after a time t decays as e(-E0t) for long times. The same quantity E-0 also determines the confinement free energy per unit length Deltaf = k(B)T E-0 of a semiflexible polymer in a narrow cylindrical pore with cross section A. From simulations of a randomly accelerated particle we estimate the universal amplitude of Deltaf for both circular and rectangular cross sections.
