We use the coordinate Bethe ansatz to study the Lieb-Liniger model of a
one-dimensional gas of bosons on a finite-sized ring interacting via an
attractive delta-function potential. We calculate zero-temperature correlation
functions for seven particles in the vicinity of the crossover to a localized
solitonic state and study the dynamics of a system of four particles quenched
to attractive interactions from the ideal-gas ground state. We determine the
time evolution of correlation functions, as well as their temporal averages,
and discuss the role of bound states in shaping the postquench correlations and
