Analytic bootstrap of mixed correlators in the O(n) CFT
Journal of High Energy Physics, 2022 We use large spin perturbation theory and the Lorentzian inversion formula to compute order-ϵ corrections to mixed correlators in the O(n) Wilson-Fisher CFT in 4 − ϵ dimensions.

Narain CFTs and quantum codes at higher genus
Journal of High Energy Physics, 2023 Code CFTs are 2d conformal field theories defined by error-correcting codes. Recently, Dymarsky and Shapere generalized the construction of code CFTs to include quantum error-correcting codes. In this paper, we explore this connection at higher genus. We

The star matter composed of nucleons deep inside the compact star like a neutron star is believed to be very dense and various new types of concepts and physical phenomena due to the nontrivial strong correlations are naturally expected. Peudo-conformality in dense star matter has been discussed recently assuming the hidden underlying scale symmetry ...

Quantum many-body conformal dynamics: Symmetries, geometry, conformal tower states, and entropy production [PDF]
Physical Review A, 2019 In this article we study the quench dynamics of Galilean and scale invariant many-body systems which can be prepared using interacting atomic gases. The far-away from equilibrium dynamics are investigated by employing $m$-body density matrices, which are

Planck scale from broken local conformal invariance in Weyl geometry [PDF]
Proceedings of Corfu Summer Institute 2019 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2019), 2019 We show that in a quadratic gravity based on Weyl's conformal geometry, the Planck mass scale can be generated from quantum effects of the gravitational field and the Weyl gauge field via the Coleman-Weinberg mechanism where a local scale symmetry is ...

Tensors and spinors in de Sitter space
Journal of High Energy Physics, 2022 We construct the Wightman function for symmetric traceless tensors and Dirac fermions in dS d+1 in a coordinate and index free formalism using a d + 2 dimensional ambient space. We expand the embedding space formalism to cover spinor and tensor fields in

On the symmetries of cosmological perturbations [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 The space of inflationary models is vast, containing wide varieties of mechanisms, symmetries, and spectra of particles. Consequently, the space of observational signatures is similarly complex. Hence, it is natural to look for boundaries of the space of

A CFT interpretation of cosmological correlation functions in α−vacua in de-Sitter space
Journal of High Energy Physics, 2023 De-Sitter(dS) space allows for a generalized class of vacua, known as α–vacua, described by some parameters. The Bunch-Davies (BD) vacuum is a point in this parameter space. The cosmological correlation function in BD vacuum in four dimensions and can be

The conformal bootstrap: Theory, numerical techniques, and applications [PDF]
Reviews of Modern Physics, 2018 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, magnets, and numerous other materials, while at the same time sit at the

Machine learning etudes in conformal field theories [PDF]
Int. J. Data Sci. Math. Sci., 2020 We demonstrate that various aspects of Conformal Field Theory are amenable to machine learning. Relatively modest feed-forward neural networks are able to distinguish between scale and conformal invariance of a three-point function and identify a ...
