What Does NEGF Stand For?

NEGF stands for Nonequilibrium Green Function

NEGF, or Nonequilibrium Green Function, is a theoretical framework used in quantum mechanics and many-body physics to describe the dynamics of quantum systems out of equilibrium. It facilitates the analysis of a variety of physical phenomena, including transport processes in mesoscopic systems and interacting particles. By employing Green's functions, NEGF allows for the calculation of electronic properties, correlation functions, and response functions of systems subjected to external perturbations, making it a vital tool in fields such as condensed matter physics, nanotechnology, and quantum transport.
