Dynamic correlations in Calogero-Sutherland model
G. Lleopart Motis, D. M. Gangardt, M. Pustilnik +1
The Calogero-Sutherland model represents a paradigmatic example of an integrable quantum system with applications ranging from cold atoms to random matrix theory. Combining sum rul…
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…
Relaxation of a high-energy quasiparticle in a one-dimensional Bose gas
Shina Tan, Michael Pustilnik, Leonid I. Glazman
We evaluate the relaxation rate of high-energy quasiparticles in a weakly interacting one-dimensional Bose gas. Unlike in higher dimensions, the rate is a nonmonotonic function of…
