A systematic 1/c-expansion of form factor sums for dynamical correlations in the Lieb-Liniger model
We introduce a framework for calculating dynamical correlations in the Lieb-Liniger model in arbitrary energy eigenstates and for all space and time, that combines a Lehmann representation with a 1/c expansion. The nth term of the expansion is of order 1/cn and takes into account all [n/2] + 1 parti...
