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 (…
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…
