Query: Entanglement Renormalization for Interacting Field Theories   A general method to build the entanglement renormalization (cMERA) for
interacting quantum field theories is presented. We improve upon the well-known
Gaussian formalism used in free theories through a class of variational
non-Gaussian wavefunctionals for which expectation values of local operators
can be efficiently calculated analytically and in a closed form. The method
consists of a series of scale-dependent nonlinear canonical transformations on
the fields of the theory under consideration. Here, the $\lambda\, \phi^4$ and
the sine-Gordon scalar theories are used to illustrate how non-perturbative
effects far beyond the Gaussian approximation are obtained by considering the
energy functional and the correlation functions of the theory.
