Optical theorem and effective action: new proofs of old results in QFT
Sergio L. Cacciatori, Andrea Zanzi
A new proof of the optical theorem at all orders is presented. Although the theorem is a well-known result in Quantum Field Theory, our proof is interesting because it is particula…
Chronons in M-theory and F-theory
Andrea Zanzi
We consider a model originally proposed in the framework of supergravity in singular spaces. This model is considered as a good summary of the expected features of M-theory and F-t…
Quantum mechanics before the big bang in heterotic-M-theory
Andrea Zanzi
In this letter we investigate the role played by quantum mechanics before the big-bang in heterotic-M-theory assuming an orbifold compactification of time. As we will see particles…
The cosmological constant problem in heterotic-M-theory and the orbifold of time
Andrea Zanzi
Chameleon fields are quantum fields with an increasing mass as a function of the matter density of the environment. Recently chameleon fields have been exploited to solve the cosmo…
Chameleonic Theories: A Short Review
Andrea Zanzi
In the chameleon mechanism, a field (typically scalar) has a mass that depends on the matter density of the environment: the larger is the matter density, the larger is the mass of…
Chameleon fields and solar physics
Andrea Zanzi, Barbara Ricci
In this article we discuss some aspects of solar physics from the standpoint of the so-called chameleon fields (i.e. quantum fields, typically scalar, where the mass is an increasi…
