Truncated Polyakov bootstrap
Kaushik Kangshabanik, Apratim Kaviraj, Shailesh Lal
We set up a truncated numerical approach in the Polyakov bootstrap (PB) framework. We employ a gradient descent optimization to solve PB sum rules numerically, and hence solve cros…

Shailesh Lal, Suvajit Majumder, Evgeny Sobko
We provide a novel Neural Network architecture that can: i) output R-matrix for a given quantum integrable spin chain, ii) search for an integrable Hamiltonian and the correspondin…

We review recent work in machine learning aspects of conformal field theory and Lie algebra representation theory using neural networks.
The World in a Grain of Sand: Condensing the String Vacuum Degeneracy
Yang-Hui He, Shailesh Lal, M. Zaid Zaz
We propose a novel approach toward the vacuum degeneracy problem of the string landscape, by finding an efficient measure of similarity amongst compactification scenarios. Using a…
Machine Learning Lie Structures & Applications to Physics
Heng-Yu Chen, Yang-Hui He, Shailesh Lal +1
Classical and exceptional Lie algebras and their representations are among the most important tools in the analysis of symmetry in physical systems. In this letter we show how the…
