periodic potential

In the second model, the temperature of periodic potential is periodically oscillating and the time structure of oscillation will affect the directed transport of Brownian particles.

在第二个模型中，布朗马达的不对称周期性势场的温度随时振荡，振荡的时间结构影响粒子定向输运，所得结果表明方形波的振荡结构并不总是最利于粒子的定向输运。

The BEC atoms confined in periodic potential wells induced by optics share not only many properties of electrons in solid but also hydrodynamics properties of nonlinear materials and other nonlinear systems. Therefore, the field of matter wave attracts extensive research interests of investigators.

局限于光诱导的周期性势阱（光势阱）中的BEC原子不仅具有固体中电子的许多性质，还具备非线性物质和其它非线性体系中的波动性质，所以引起了研究者的广泛研究兴趣。
