摘要
We consider the local field dynamic temperature correlation function of the quantum nonlinear Schrodinger equation with a finite coupling constant. This correlation function admits a Fredholm determinant representation. The related operator-valued Riemann-Hilbert problem is used to analyze the leading term of the large time and distance asymptotic expansion of the correlation function.
