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…

Decay of Bogoliubov excitations in one-dimensional Bose gases
Zoran Ristivojevic, K. A. Matveev
We study the decay of Bogoliubov quasiparticles in one-dimensional Bose gases. Starting from the hydrodynamic Hamiltonian, we develop a microscopic theory that enables one to syste…

Thermalization of acoustic excitations in a strongly interacting one-dimensional quantum liquid
Jie Lin, K. A. Matveev, M. Pustilnik
We study inelastic decay of bosonic excitations in a Luttinger liquid. In a model with linear excitation spectrum the decay rate diverges. We show that this difficulty is resolved…
