Two loop results from the derivative expansion of the blocked action
Alfio Bonanno, Dario Zappala'
A derivative expansion of the Wegner-Houghton equation is derived for a scalar theory. The corresponding full non-perturbative renormalization group equations for the potential and…

Fixed point analysis of a scalar theory with an external field
A. Bonanno, D. Zappala'
A momentum dependent projection of the Wegner-Hougton equation is derived for a scalar theory coupled to an external field. This formalism is useful to discuss the phase diagram of…
