Abstract:
The correlation function of the currents in a one-dimensional Bose gas is investigated by means of the series constructed in earlier work [1–3]. The higher corrections are calculated. The large-distance asymptotic behavior is investigated at both zero temperature and finite temperature. Particular attention is devoted to calculation of the pre-exponential factor.
