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…
Fate of classical solitons in one-dimensional quantum systems
M. Pustilnik, K. A. Matveev
We study one-dimensional quantum systems near the classical limit described by the Korteweg-de Vries (KdV) equation. The excitations near this limit are the well-known solitons and…
Electrical and Thermal Transport in Inhomogeneous Luttinger Liquids
Wade DeGottardi, K. A. Matveev
We study the transport properties of long quantum wires by generalizing the Luttinger liquid approach to allow for the finite lifetime of the bosonic excitations. Our theory accoun…
Solitons in a one-dimensional Wigner crystal
M. Pustilnik, K. A. Matveev
In one-dimensional quantum systems with strong long-range repulsion particles arrange in a quasi-periodic chain, the Wigner crystal. We demonstrate that besides the familiar phonon…
Scattering of charge and spin excitations and equilibration of a one-dimensional Wigner crystal
K. A. Matveev, A. V. Andreev, A. D. Klironomos
We study scattering of charge and spin excitations in a system of interacting electrons in one dimension. At low densities electrons form a one-dimensional Wigner crystal. To first…
