Webas determined with density functional theory, which also provides a suitable basis). Then the interaction must be treated reliably, and for this dynamical mean-field theory (DMFT) and re-lated theories provide a controlled approach. The spirit and some technical aspects of DMFT were already mentionedin the Lecture of D. Vollhardt. WebNov 5, 2024 · Dynamical mean field theory (DMFT) is a tool that allows one to analyze the stochastic dynamics of N interacting degrees of freedom in terms of a self-consistent 1-body problem. In this work, focusing on models of ecosystems, we present the derivation of DMFT through the dynamical cavity method, and we develop a method for solving it numerically.
