通过求解粒子在沿着周期势场中运动的与时间无关的本征值问题，计算了熵产生的大偏差函数。在一个中间的力制度，大偏差函数显示出明显的偏差，从高斯行为的特征“扭结”在零熵产生。这样的特征也可以从非对称随机行走的解析解中提取，在一定的参数范围内可以将被驱动的粒子映射到该解析解。
The large deviation function for entropy production is calculated by solving a time-independent eigenvalue problem for a particle driven along a periodic potential. In an intermediate force regime, the large deviation function shows pronounced deviations from a Gaussian behavior with a characteristic "kink" at zero entropy production. Such a feature can also be extracted from the analytical solution of the asymmetric random walk to which the driven particle can be mapped in a certain parameter range.
