The observable-state model and non-renormalizable theories
Juan Sebastián Ardenghi, Alfredo Juan, Mario Castagnino
The aim of this work is to apply the observable-state model for the quantum field theory of a ϕ^n self- interaction. We show how to obtain finite values for the 2-point and n-point…
Renormalization: the observable-state model Part II
Juan Sebastián Ardenghi, Mario Castagnino
The purpose of this work is to rewrite the generating functional of phi^4 theory for the n = 0 and n = 4 correlation functions as the inner product of a state with an observable, a…
Renormalization: the observable-state model
Juan Sebastián Ardenghi, Mario Castagnino
The usual mathematical formalism of quantum field theory is non-rigorous because it contains divergences that can only be renormalized by non-rigorous mathematical methods. The pur…
The non-relativistic limit of (central-extended) Poincare group and some consequences for quantum actualization
Juan Sebastián Ardenghi, Mario Castagnino, Rutwig Campoamor-Sturberg
The nonrelativistic limit of the centrally extended Poincaré group is considered and their consequences in the modal Hamiltonian interpretation of quantum mechanics are discussed […
