Thirring–Wess model

The Thirring-Wess model is a theoretical framework used in quantum field theory that describes the dynamics of fermionic fields. It is primarily a two-dimensional model that provides insights into the behavior of quantum fields with interactions. The model is notable because it exhibits non-trivial interactions between fermions and can lead to rich phenomena such as spontaneous symmetry breaking and the emergence of various phases. The model is characterized by its Lagrangian density, which typically includes terms for free fermions and interaction terms.
