Short-time large deviations of first-passage functionals for high-order stochastic processes

Lulu Tian, Hanshuang Chen, Guofeng Li

We consider high-order stochastic processes $x (t)$ described by the Langevin equation $\frac{d ^{m} x ( t )}{d t ^{m}} = 2 D I^¾ (t)$ , where $I^¾ (t)$ is a delta-correlate…

Short-time large deviation of constrained random acceleration process

Hanshuang Chen, Lulu Tian, Guofeng Li

By optimal fluctuation method, we study short-time distribution $P (A = A)$ of the functionals, $A = \int_{0}^{t_{f}} x^{n} (t) d t$ , along constrained trajectories of ran…
