However, as we will see, utilizing Feynman's path-integral formulation of quantum mechanics, Gaussian integrals are also central for computation in quantum statistical mechanics and more generally in quantum field theory. A. one degree of freedom Let us start out slowly with standard, scalar, one-dimension Gaussian integrals Z 0(a) = Z ∞.
