Abstract
Using a hydrodynamic description, we study the properties of the one-dimensional Calogero-Sutherland model. The correlation function of quasiparticle excitations (anions) is calculated by the instanton technique. The instanton trajectory is given by a solitary wave propagating through a quantum fluid. The smooth part of the quasiparticle correlation function far from the light cone oscillates as a function of coordinate.
