论文摘要
我们已经研究了带有周期性踢球和正弦交流偏置电压的几何纳米机电班车中的校正电流。在几何对称性下，整流电流完全为零，该对称是由通过可移动班车从源到排水电极传递的电子产生的。我们通过对称班车进行了非零的整流电流，并定期运动，其时间翻译对称性被损坏。此外，航天飞机的运动与踢旋翼的相同机理变得混乱，并随着踢球强度的增加而产生散射的电流。我们指出，瞬时电流的时间翻译对称破坏是操纵整流电流的重要作用。
We have studied the rectified current in a geometrically symmetric nano-electromechanical shuttle with periodic kicks and sinusoidal ac bias voltages. The rectified current is exactly zero under the geometrical symmetry which is generated by the electrons transferred from source to drain electrodes through the movable shuttle. We investigate the nonzero rectified currents through the symmetric shuttle with regular motion of which the time-translational symmetry is broken. The motion of the shuttle, moreover, becomes chaotic with the same mechanism of the kicked rotor and generates the scattered current as increasing kick strength. We point out that the time-translational-symmetry breaking of the instantaneous current is an important role of manipulation of the rectified current.
