论文摘要
我们回顾了量子流体\ HE4和\ HE3动力学的物理描述中的实验和理论进步。从历史上看，这些系统中的基本激发已被识别为声子和旋转子，在\ he3中，集体零声音和自旋 - 透射。最近的高精度测量和理论方法都表明，这些系统的动力学实际上非常丰富，这将在该贡献的正文中详细讨论。
We review experimental and theoretical progress in the physical description of the dynamics of the quantum fluids \he4 and \he3. Historically, the elementary excitations in these systems have been identified as phonons and rotons and, in \he3, collective zero sound and spin-fluctuations. Both recent high-precision measurements and theoretical methods have shown that the dynamics of these systems is actually very rich as will be discussed in detail in the body of this contribution.
