Description
In this presentation, I will show how the difference of interacting and non-interacting integrated two-particle correlation functions in finite volume is related to infinite volume scattering phase shift through an integral weighted by a factor exp(-Et). The difference of integrated finite volume correlation functions converge rapidly to its infinite volume limit as the size of periodic box is increased, which offers a suitable framework to overcome the challenges that the Luscher formula faces at large volume limit.
