Gauge Theory Amplitudes from Cubic Scalar Feynman diagrams
Roji Pius
Feynman diagrams are the foremost tool in the perturbative study of quantum field theory. In gauge theories, the full potential of this tool is revealed when it is combined with th…
Island Paradigm and Information Recovery from Radiation
Krishna Jalan, Roji Pius, Manish Ramchander
The island paradigm for an AdS eternal black hole in the Hartle-Hawking state coupled to a finite temperature non-gravitating bath asserts that after the Page time the operator…
Reduced Half-sided Translations and Islands
Krishna Jalan, Roji Pius
An AdS black hole in equilibrium with a finite temperature non-gravitating bath comes with a Hawking-like information paradox. The resolution of this paradox requires introduci…
Theory dependence of black hole interior reconstruction and the extended strong subadditivity
Sitender Pratap Kashyap, Roji Pius, Manish Ramchander
An AdS eternal black hole in equilibrium with a finite temperature bath presents a Hawking-like information paradox due to a continuous exchange of radiation with the bath. The non…
Topological string entanglement
Veronika E. Hubeny, Roji Pius, Mukund Rangamani
We investigate how topological entanglement of Chern-Simons theory is captured in a string theoretic realization. Our explorations are motivated by a desire to understand how quant…
Quantum Closed Superstring Field Theory and Hyperbolic Geometry I: Construction of String Vertices
Roji Pius
The complete quantum theory of closed superstrings is constructed using string diagrams endowed with metric having constant curvature . The elementary string diagrams are equip…
