The Cosmological -shift
Carolina Figueiredo, Jiajie Mei, Yuyu Mo +1
We consider the extension of the -shift connecting Tr and pion amplitudes to observables in cosmology. We start in flat-space and explain how one can extract the pion wav…
Correlators are simpler than wavefunctions
Nima Arkani-Hamed, Ross Glew, Francisco Vazão
Recent works reveal a simplicity in equal-time correlators absent from wavefunctions. We show that it follows from the fact that correlators are full spacetime integrals, rather th…
Correlator Polytopes
Carolina Figueiredo, Francisco Vazão
Recently, "cosmohedra" have been introduced as polytopes underlying the cosmological wavefunction for conformally coupled Tr() theory in FRW cosmologies, generalizing associah…
Cosmohedra
Nima Arkani-Hamed, Carolina Figueiredo, Francisco Vazão
It has been a long-standing challenge to find a geometric object underlying the cosmological wavefunction for Tr() theory, generalizing associahedra and surfacehedra for scatt…
