我们已经进行了空间分辨测量的电荷密度波（CDW）响应双极电流脉冲。这些测量直接产生CDW弹性力剖面的时间演化和CDW相滑移的分布。稳态弹性力分布与相位滑移分布强烈耦合。这种耦合增加了电流接触附近的CDW应变梯度，并减小了发生显著相位滑移的区域的尺寸。我们描述了一个模型的CDW动力学中存在的相位滑移，提供了一个很好的帐户的复杂的时空响应。
We have performed spatially resolved measurements of the charge-density-wave (CDW) response to bipolar current pulses. These measurements directly yield the temporal evolution of the CDW elastic force profile and the distribution of CDW phase slip. The steady-state elastic force profile is strongly coupled to the phase-slip distribution. This coupling increases the CDW strain gradient near the current contacts, and reduces the size of the region in which significant phase slip occurs. We describe a model for CDW dynamics in the presence of phase slip that provides an excellent account of the complex spatiotemporal response.
