The transport of a chain of charged particles with a transverse degree of freedom is investigated in a 2D asymmetric potential. Here, the energy of the periodic driving force is converted into motion in the vertical direction. The analysis exhibits a transition from stick–slip motion to periodic oscillation. The chain velocity can be controlled to an optimized value by adjusting system parameters, such as the amplitude and frequency of the periodic force. The existence of a resonance platform indicates resonance between the motion of the chain and the periodic force as coupling strength increases adiabatically. The atomic configuration and the transverse degree of freedom also play key roles in the control.

2D衬底电势中带电粒子链的动态过渡

在二维不对称电势中研究了具有横向自由度的带电粒子链的传输。在此，周期性驱动力的能量被转换为在垂直方向上的运动。分析显示了从粘滑运动到周期性振动的过渡。通过调整系统参数（例如周期性力的振幅和频率），可以将链速控制到最佳值。共振平台的存在表明链的运动与周期性力之间的共振，因为耦合强度呈绝热增加。原子构型和横向自由度在控制中也起着关键作用。
