| dc.description.abstract | vVe considered a Brownian particle trying to escape from a single-well potential with a run away on one side aided by the thermal energy of the medium in which it is moving, The analytical expression of escape rate of a Brownian particle is calculated for a model original potential (inverted N) and for a modified model potential having an intermediate metastable state using supersymmetric and mean first passage time methods. The modified model potential is parameterized by location and slope of the intermediate metastable state. We compared the escape rate for the modified model potential with that for the original a model potential and found that their ratio takes optimum value at a particular position of the intermediate state. In addition, this ratio takes optimum value at a particular slope value of the intermediate state | en_US |
