Bulk Criticality and Boundary Spectra in AdS from Matrix Product States
Faizan Bhat
We study interacting scalar quantum field theories in anti-de Sitter (AdS) space using a tensor-network approach based on matrix product states. We develop methods for extracting l…
A stringy dispersion relation for field theory
Faizan Bhat, Arnab Priya Saha, Aninda Sinha
We derive a local, crossing symmetric dispersion relation (CSDR) for 2-2 scattering amplitudes with a parametric ambiguity motivated by string theory. Various limits of the paramet…
Ramanujan's series and conformal field theories
Faizan Bhat, Aninda Sinha
In 1914, Ramanujan unveiled 17 extraordinary infinite series for . In this work, we uncover their physics origin by relating them to 2D logarithmic conformal field theories (L…
Bootstrapping string models with entanglement minimization and Machine-Learning
Faizan Bhat, Debapriyo Chowdhury, Arnab Priya Saha +1
We present a new approach to bootstrapping string-like theories by exploiting a local crossing symmetric dispersion relation and field redefinition ambiguities. This approach enabl…
Perturbative Mellin amplitudes of SYM
Faizan Bhat, Pronobesh Maity
We compute the Mellin amplitude of the planar four-point correlator of weight-two half-BPS operators in SYM at one and two-loop orders in the small 't Hooft couplin…
Bootstrapping High-Energy Observables
Faizan Bhat, Debapriyo Chowdhury, Aninda Sinha +2
In this paper, we set up the numerical S-matrix bootstrap by using the crossing symmetric dispersion relation (CSDR) to write down Roy equations for the partial waves. As a motivat…
A Celestial Route to AdS Bulk Locality
Faizan Bhat, Ahmadullah Zahed
We prove a precise form of AdS bulk locality by deriving analytical two-sided bounds on bulk Wilson coefficients. Our bounds are on the Wilson coefficients themselves, rather than…
Twistor Coverings and Feynman Diagrams
Faizan Bhat, Rajesh Gopakumar, Pronobesh Maity +1
Recently, a worldsheet dual to free Super Yang-Mills has been proposed in terms of twistor variables for , in parallel to that for the dual…
