Sphere path integrals for fermionic gauge fields
Chiara Baracco, Vasileios A. Letsios
We consider spin- complex, strictly massless fermionic gauge fields on the four-sphere, , which is the Euclidean continuation of de Sitter spacetime, dS$_4…
A discrete series gauge field at the late-time boundary of
Manizheh Botshekananfard, Elif Büşra Güraksın, Vasileios A. Letsios +1
We study the free Maxwell field on the planar patch of four-dimensional de Sitter spacetime (). We review its bulk canonical quantization in the Bunch-Davies vacuum, and we g…
Axions on de Sitter space
Vasileios A. Letsios, Stathis Vitouladitis
We study a massless minimally coupled compact scalar, or axion, on global -dimensional de Sitter space (dS). We quantise the theory canonically, determine the quantum dS cha…
dS Metamorphosis
Dionysios Anninos, Chiara Baracco, Vasileios A. Letsios +1
We study the Euclidean path integral of higher spin gravity on . Based on a one-loop analysis, we are led to a gluing formula expressing the path integral in terms of an…
The complete action for de Sitter pure supergravity
Nicolas Boulanger, Vasileios A. Letsios, Sylvain Thomée
Supergravity theories in de Sitter spacetime are known to be very constrained, and rather unnatural within String/M Theory. We revisit the seminal paper by Pilch, van Nieuwenhuizen…
