The Nonlinear Dirac Equation is a modification of the standard Dirac equation, which describes fermionic particles, such as electrons, in the framework of quantum mechanics and quantum field theory. The standard Dirac equation is linear and represents the relativistic wavefunction of spin-½ particles, preserving properties such as probability conservation and Lorentz invariance.
