Green's function of quasiparticles in Calogero model and quantum hydrodynamics
Using hydrodynamic description we study properties of one-dimensional Calogero-Sutherland model. Correlation function of quasi-particle excitations (anions) is calculated by instanton technique. The instanton trajectory is given by solitary wave propagating through quantum fluid. Smooth part of quasi-particles correlation function far from light cone oscillates as function of coordinate. © 2008 The American Physical Society.
