在对称三井势中，驱动热活化粒子的两个噪声过程之间的相关性可能会导致对称破缺，以及两侧井相对于中间井的相对稳定性的差异。这导致了种群的不对称定位和中间井Kramers逃逸率的分裂，确保了平行反应过程中产物的优先分配。
A correlation between two noise processes driving the thermally activated particles in a symmetric triple-well potential may cause a symmetry breaking and a difference in relative stability of the two side wells with respect to the middle one. This leads to an asymmetric localization of population and splitting of Kramers' rate of escape from the middle well, ensuring a preferential distribution of the products in the course of a parallel reaction.
