The need for a nonlocal expansion in general relativity
Marco Galoppo, Giorgio Torrieri
Motivated by known facts about effective field theory and non-Abelian gauge theory, we argue that the post-Newtonian approximation might fail even in the limit of weak fields and s…

Chiral oscillations in finite time quantum field theory
Massimo Blasone, Francesco Giacosa, Luca Smaldone +1
We demonstrate how chiral oscillations of a massive Dirac field can be described within quantum field theory using a finite-time interaction picture approach, where the mass term i…
