The Sine-Gordon QFT in de Sitter spacetime
Daniela Cadamuro, Markus B. Fröb, Carolina Moreira Ferrera
We consider the massless Sine-Gordon model in de Sitter spacetime, in the regime and using the framework of perturbative algebraic quantum field theory. We show that a…
Heat kernel coefficients for massive gravity
Renata Ferrero, Markus B. Fröb, William C. C. Lima
We compute the heat kernel coefficients that are needed for the regularization and renormalization of massive gravity. Starting from the Stueckelberg action for massive gravity, we…
Universal definition of the non-conformal trace anomaly
Renata Ferrero, Sebastián A. Franchino-Viñas, Markus B. Fröb +1
We show that there exists a generalized, universal notion of the trace anomaly for theories which are not conformally invariant at the classical level. The definition is suitable f…
Modular Hamiltonian for fermions of small mass
Daniela Cadamuro, Markus B. Fröb, Christoph Minz
We consider the algebra of massive fermions restricted to a diamond in two-dimensional Minkowski spacetime, and in the Minkowski vacuum state. While the massless modular Hamiltonia…
Relative Entropy in de Sitter is a Noether Charge
Markus Fröb, Albert Much, Kyriakos Papadopoulos
We compute the relative entropy between the vacuum and a coherent state for a massive scalar field in de Sitter spacetime, using Tomita-Takesaki modular theory and the Araki-Uhlman…
