Dynamical mean-field theory (DMFT) is a successful method to investigate interacting lattice fermions. In these lecture notes we present an introduction into the DMFT for lattice fermions with interaction, disorder and external inhomogeneous potentials. This formulation is applicable to electrons in ...

Nonequilibrium statistical mechanics exhibit a variety of complex phenomena far from equilibrium. It inherits challenges of equilibrium, including accurately describing the joint distribution of a large number of configurations, and also poses new challe
Here, the statistical quantities, i.e meanE[·] and varianceVar[·], are determined for the objective functionM(x(tf)), path constraintshp(x(t)), and terminal constraintsht(x(tf)). The weight factorc0translates the resulting multi-objective problem into a single-objectiveexpression. Theineq...
Third, focusing on the detection of conformation changes in molecules, mean field theory is used to approximate the marginal dynamics on low-dimensional subsystems. Also, conditions are given under which the Galerkin projection of a transfer operator can be related to the small random perturbation ...
