What Does ADCN Stand For?

ADCN stands for Algebraic Diagrammatic Construction Method In Nth Order Perturbation Theory

ADCN, or Algebraic Diagrammatic Construction Method in Nth Order Perturbation Theory, is a mathematical framework utilized in quantum many-body physics. It systematically constructs Green's functions and other correlation functions by employing diagrammatic techniques in perturbation theory. This method efficiently accounts for interactions within complex systems, allowing for accurate computations in high-order perturbative expansions. ADCN is particularly valuable in applications such as condensed matter physics and quantum chemistry, where it facilitates the exploration of electronic correlations and phase transitions.
