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…

Low-energy excitations of a one-dimensional Bose gas with weak contact repulsion
M. Pustilnik, K. A. Matveev
We study elementary excitations of a system of one-dimensional bosons with weak contact repulsion. We show that the Gross-Pitaevskii regime, in which the excitations are the well-k…

Decay of Bogoliubov quasiparticles in a nonideal one-dimensional Bose gas
Zoran Ristivojevic, K. A. Matveev
We study the relaxation of excitations in a system of one-dimensional weakly interacting bosons. Due to residual weak interactions, Bogoliubov quasiparticles in this system have fi…
