The Gross–Neveu model

The Gross–Neveu model is a theoretical framework in particle physics that describes interacting fermions (particles like electrons) using simpler mathematical techniques. It was developed to study the dynamics of these particles in lower dimensions, which can provide insights into more complex systems. The model is important for understanding behavior like phase transitions and symmetry breaking in quantum field theory. Essentially, it helps physicists explore how fundamental particles interact and how these interactions may lead to various physical phenomena, aiding in the understanding of the forces that govern the universe at a fundamental level.
