Propagation and attenuation of sound in one-dimensional quantum liquids
K. A. Matveev, A. V. Andreev
At low temperatures, elementary excitations of a one-dimensional quantum liquid form a gas that can move as a whole with respect to the center of mass of the system. This internal…

Hybrid sound modes in one-dimensional quantum liquids
K. A. Matveev, A. V. Andreev
We study sound in a single-channel one-dimensional quantum liquid. In contrast to classical fluids, instead of a single sound mode we find two modes of density oscillations. The sp…
