Correlation Functions of the One-Dimensional Attractive Bose Gas
Pasquale Calabrese, Jean-Sébastien Caux
Abstract
The zero-temperature correlation functions of the one-dimensional attractive Bose gas with a delta-function interaction are calculated analytically for any value of the interaction parameter and number of particles, directly from the integrability of the model. We point out a number of interesting features, including zero recoil energy for a large number of particles, analogous to the Mössbauer effect.
