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…

Unitarity of the Box Diagram
Roji Pius, Ashoke Sen
The complete proof of cutting rules needed for proving perturbative unitarity of quantum field theories usually employs the largest time equation or old fashioned perturbation theo…
