Dynamics of excitations in a one-dimensional Bose liquid
arXiv:0705.2015 · doi:10.1103/PhysRevLett.99.110405
Abstract
We show that the dynamic structure factor of a one-dimensional Bose liquid has a power-law singularity defining the main mode of collective excitations. Using the Lieb-Liniger model, we evaluate the corresponding exponent as a function of the wave vector and the interaction strength.
