Examining a covariant and renormalizable quantum field theory in de Sitter space by studying "black hole radiation"
Hamed Pejhan, Surena Rahbardehghan
Respecting that any consistent quantum field theory in curved space-time must include black hole radiation, in this paper, we examine the Krein-Gupta-Bleuler (KGB) formalism as an…

The Krein-Gupta-Bleuler Quantization in de Sitter Space-time; Casimir Energy-Momentum Tensor for a Curved Brane
S. Rahbardehghan, H. Pejhan
In this paper, vacuum expectation value (VEV) of the energy-momentum tensor for a conformally coupled scalar field in de Sitter space-time is investigated through the Krein-Gupta-B…

A Group Theoretical Approach to Graviton Two-Point Function
S. Rahbardehghan, H. Pejhan, M. Elmizadeh
Respecting the group theoretical approach, it is debated that the theory of linear conformal gravity should be formulated through a tensor field of rank-3 and mixed symmetry \cite{…
