Quantum Information with Fermionic Gaussian States - Max
... In physics, Gaussian approximation is a frequently used tool for solving many-body problems. Gaussian approximation relies on describing system fully in terms of two-point correlation functions. This means that all the higher order correlations can be expressed as a product of two-point correlation ...
