Effective potentials for de Sitter and anti de Sitter quantum fields

Alfio Bonanno, Sergio Luigi Cacciatori, Ugo Moschella

We derive a systematic treatment of one-loop effective potentials for interacting scalar fields in curved spacetimes, providing a general formula valid in arbitrary geometries and…

Two point functions and quantum fields in the anti-de Sitter universe

Ugo Moschella

We construct a manifestly covariant and coordinate-free plane-wave representation of scalar two-point functions in -dimensional anti-de Sitter spacetime. The construction is bas…

Anti-de Sitter, plane waves and quantum field theory

Ugo Moschella

We present a new plane-wave expansion of the Wightman functions of anti de Sitter scalar fields and showcase its conceptual and technical importance in AdS quantum field theory. We…

Plane waves, harmonic analysis in de Sitter and anti de Sitter Quantum Field Theory and the spectral condition

Ugo Moschella

We review the role of the spectral condition as a characteristic feature unifying Minkowski, de Sitter and anti de Sitter Quantum Field Theory. In this context, we highlight the ro…

Loops in de Sitter space

Sergio L. Cacciatori, Henri Epstein, Ugo Moschella

We discuss general one and two-loops banana diagrams with arbitrary masses on the de Sitter spacetime by using direct methods of dS quantum field theory in the dimensional regulari…

Loops in Anti de Sitter space

Sergio L. Cacciatori, Henri Epstein, Ugo Moschella

We discuss general one and two-loop banana diagrams and one-loop diagrams with external lines with arbitrary masses on the anti de Sitter spacetime by using methods of AdS quantum…
