Description
Full counting statistics (FCS) of operators is a central object of study in statistical physics. Using the quantum inverse scattering method and the modified algebraic Bethe ansatz, we derive an explicit expression for the FCS in the form of a form factor expansion. This expansion provides the basis for establishing the asymptotic behavior of the FCS. We further consider quantum quenches from integrable initial states and obtain the corresponding long-distance asymptotics.
