Spectral Functions of Local Operators In The Tomonaga-Luttinger Model
S. P. Strong
Abstract
I give a simple general prescription for computing the spectral functions of local operators in the Tomonaga-Luttinger model from the space-time correlation functions. The method is significantly simpler than directly transforming the space-time Greens function and allows a physical interpretation of the singularities encountered in the spectral function.
