This review aims to offer a pedagogical introduction to the analytic conformal bootstrap
program via a journey through selected topics. We review analytic methods which include …

A bstract We describe in more detail the general relation uncovered in our previous work
between boundary correlators in de Sitter (dS) and in Euclidean anti-de Sitter (EAdS) space …

The double copy is, in essence, a map between scattering amplitudes in a broad variety of
familiar field and string theories. In addition to the mathematically rich intrinsic structure, it …

A bstract A number of diagrammatic “cutting rules” have recently been developed for the
wavefunction of the Universe which determines cosmological correlation functions. These …

A bstract Massive spinning particles acquire helicity-dependent chemical potentials during
the inflation from axion-type couplings. Such spinning fields can mediate sizable inflaton …

A bstract Phenomenological studies of cosmological collider physics in recent years have
identified many 1-loop inflation correlators as leading channels for discovering heavy new …

A bstract Inflation correlators with one-loop massive exchange encode rich information
about the dynamics of the massive loop particles. Their nonanalytic behavior in certain soft …

A bstract The dynamics of quantum fields during cosmic inflation can be probed via their late-
time boundary correlators. The analytic structure of these boundary correlators contains rich …

A bstract The AdS boundary correlators and their dual correlation functions of boundary
operators have been the main dynamic observables of the holographic duality relating a …

A bstract The tree-level wavefunction coefficient for four gravitons in de Sitter space was
recently bootstrapped using the Cosmological Optical Theorem, flat space limit, and …
