Kontorovich-Lebedev-Fourier Space for de Sitter Correlators
Nathan Belrhali, Arthur Poisson, Sébastien Renaux-Petel +1
In this work, we build a novel frequency-momentum space for -dimensional de Sitter (dS) correlators from first principles. This construction follows directly from the decomp…

De Sitter Momentum Space
Nathan Belrhali, Arthur Poisson, Sébastien Renaux-Petel +1
We construct a natural and nonperturbative momentum space for quantum field theory on -dimensional de Sitter (dS) spacetime in the Poincaré slicing, adapted to early Univers…
