Title: Non Relativistic Limit of Integrable QFT with fermionic excitations,
Abstract: The aim of this paper is to investigate the non-relativistic limit of
integrable quantum field theories with fermionic fields, such as the O(N)
Gross-Neveu model, the supersymmetric Sinh-Gordon and non-linear sigma models.
The non-relativistic limit of these theories is implemented by a double scaling
limit which consists of sending the speed of light c to infinity and rescaling
at the same time the relevant coupling constant of the model in such a way to
have finite energy excitations. For the general purpose of mapping the space of
continuous non-relativistic integrable models, this paper completes and
integrates the analysis done in Ref.[1] on the non-relativistic limit of purely
bosonic theories.
