摘要：

The influence of tether dynamics on forced Kramers escape from a kinetic trap was studied. The full Kramers escape problem for the coupled system was solved using a technique attributed to Langer which considers a mass and spring polymer coupled to a trapping potential. It was found that the forced-Kramers escape rate can be significantly altered by the properties of the polymeric spring. Increase in the polymeric mass and overall drag was found to decrease the escape rate, however a shift of drag from the trapped particle to the polymer increased the escape rate.
