Conformal field theories have been long known to describe the fascinating universal physics
of scale invariant critical points. They describe continuous phase transitions in fluids …

A bstract We study the fundamentals of quantum field theory on a rigid de Sitter space. We
show that the perturbative expansion of late-time correlation functions to all orders can be …

A bstract It is a long-standing conjecture that any CFT with a large central charge and a large
gap∆ gap in the spectrum of higher-spin single-trace operators must be dual to a local …

A bstract Primordial perturbations in our universe are believed to have a quantum origin,
and can be described by the wavefunction of the universe (or equivalently, cosmological …

A bstract Carrollian Conformal Field Theories (CFTs) have been proposed as co-dimension
one holographic duals to asymptotically flat spacetimes as opposed to Celestial CFTs which …

A bstract We present a systematic study of holographic correlators in a vast array of SCFTs
with non-maximal superconformal symmetry. These theories include 4d\(\mathcal {N}\)= 2 …

The S-matrix Bootstrap originated on the idea that the S-matrix might be fully constrained by
global symmetries, crossing, unitarity, and analyticity without relying on an underlying …

A bstract We study quantum field theory on a de Sitter spacetime dS d+ 1 background. Our
main tool is the Hilbert space decomposition in irreducible unitary representations of its …

A bstract We revisit from a modern bootstrap perspective the longstanding problem of
solving QCD in the large N limit. We derive universal bounds on the effective field theory of …

Fundamental principles of local quantum field theory or of quantum gravity can enforce
consistency requirements on the space of consistent low-energy effective field theories. We …
