One-loop effective action: nonlocal form factors and renormalization group
Poliane de Morais Teixeira, Ilya L. Shapiro, Tiago G. Ribeiro
We review and present full detail of the Feynman diagram - based and heat-kernel method - based calculations of the simplest nonlocal form factors in the one-loop contributions of…
Scalar model of effective field theory in curved space
Tiago G. Ribeiro, Ilya L. Shapiro
We consider, in more details than it was done previously, the effective low-energy behavior in the quantum theory of a light scalar field coupled to another scalar with much larger…
Gravitational form factors and decoupling in 2D
Tiago G. Ribeiro, Ilya L. Shapiro, Omar Zanusso
We calculate and analyse non-local gravitational form factors induced by quantum matter fields in curved two-dimensional space. The calculations are performed for scalars, spinors…
Stefan-Boltzmann law for massive photons
E. S. Moreira, T. G. Ribeiro
This paper generalizes the Stefan-Boltzmann law to include massive photons. A crucial ingredient to obtain the correct formula for the radiance is to realize that a massive photon…
