Brownian motion and generalized Lifson-Jackson formula in quasi-periodic systems
Sang Yang, Juyuan Sun, Guangcan Guo +1
Brownian motion in periodic potentials has been widely investigated in statistical physics and related interdisciplinary fields. In the overdamped regime, it has been well-known th…
