Bethe Ansatz and exact form factors of the O(N) Gross Neveu-model
(2016) [Artigo de periódico]We apply previous results on the O(N) Bethe Ansatz [1{3] to construct a general form factor formula for the O(N) Gross-Neveu model. We examine this formula for several operators, such as the energy momentum, the spin- eld ... -
Exact form factors of the O(N) σ-model
(2013) [Artigo de periódico]A general form factor formula for the O(N) σ-model is constructed and applied to several operators. The large N limits of these form factors are computed and compared with the 1/N expansion of the O(N) σ-model in terms of ...
