Cosmological Correlators from Scattering Amplitudes: A Review
Soner Albayrak, Savan Kharel
The primordial statistics underlying the CMB and large-scale structure are encoded in late-time cosmological correlation functions (constructed from the coefficients of the wavefun…
Soft limits of gluon amplitudes in holography and cosmology
Soner Albayrak, Savan Kharel
In this work, we extend the study of soft limits to (Anti) de Sitter spaces, investigating the analytic structure of holographic gluon correlators as part of a broader effort to re…
Momentum-space formulae for AdS correlators for diverse theories in diverse dimensions
Soner Albayrak, Savan Kharel, Xinkang Wang
In this paper, we explore correlators of a series of theories in anti-de Sitter space: we present comprehensive results for interactions involving scalars, gluons, and gravitons in…
Perturbative Unitarity and the Wavefunction of the Universe
Soner Albayrak, Paolo Benincasa, Carlos Duaso Pueyo
Unitarity of time evolution is one of the basic principles constraining physical processes. Its consequences in the perturbative Bunch-Davies wavefunction in cosmology have been fo…
All plus four point (A)dS graviton function using generalized on-shell recursion relation
Soner Albayrak, Savan Kharel
This paper presents a calculation of the four gravitons amplitude in (Anti)-de Sitter space, focusing specifically on external gravitons with positive helicity. To achieve this, we…

The Inversion Formula and 6j Symbol for 3d Fermions
Soner Albayrak, David Meltzer, David Poland
In this work we study the symbol of the conformal group for fermionic operators. In particular, we study 4-point functions containing two fermions and two scalars and als…
