摘要：Strong correlation in one-dimensional (1D) quantum systems drastically changes their dynamic and transport properties in the presence of the interaction. In this letter, combining quantum integrable theory with numerics, we exactly compute the spectral function of 1D Lieb-Liniger gas at a many-body level of large scales. It turns out that a full capture of the power-law singularities in the vicinities of thresholds requires system size as large as thousands of particles. Our research essentially confirms the validity of the nonlinear Tomonaga-Luttinger liquid and provides a reliable technique for studying critical behaviour emerged only in thermodynamic limit.
