Unformatted text preview: Jc, x = ; 0 . 6 Show that in the overdamped regime, the saddle point equation S= = 0 can be satis ed by a Lorentz function ansatz A (t) = 0 + t2 + 2 (5) Find A and and evaluate the action. Compare with the result found above for = 0. c) Consider the decay of an overdamped Josephson junction at a nite temperature. Estimate the temperature above which the T = 0 solution found in part b) is substantially modi ed. Describe the crossover from the tunneling to the Arrhenius regime in terms of the dependence ln W vs. . S=...
