Charge and Spin Density Waves

实验将考察电荷密度波(CDW)和自旋密度波(SDW)基态的动力学。这是上一笔拨款支持的研究的继续。将进行三个强相关的实验：(1)CDW和SDW凝聚体在射电、微米、毫米和红外光谱范围内的集体模交流响应；(2)在CDW态下的热电、弹性和磁性的检查；(3)寻找CDW基态的非线性激发。这些实验将在各种形成电荷或自旋密度波基态的无机有机线性链状化合物上进行。

Experiments will be carried out to examine the dynamics of charge density wave (CDW) and spin density wave (SDW) ground states. This is a continuation of research supported under a previous grant. Three strongly related experiments will be pursued: (1) the collective mode ac response of CDW and SDW condensates in the radio, micro-, millimeter, and infrared spectral range; (2) the examination of thermoelectric, elastic and magnetic properties in the CDW state, and (3) the search for non-linear excitations of the CDW ground state. The experiments will be conducted on various inorganic organic linear chain compounds which develop charge or spin density wave ground states.
