Abstract

We review experimental and theoretical progress in the physical description of the dynamics of the quantum fluids 4He and 3He. Historically, the elementary excitations in these systems have been identified as phonons and rotons and, in3He, collective zerosound 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.
