Monotones from multi-invariants: the Coxeter classification
Abhijit Gadde, Shraiyance Jain
Multi-invariants are multiplicative polynomial invariants of multipartite pure states under local unitaries. They yield entanglement monotones when their contraction graphs satisfy…

Probing Non-Graviton Spectra in SYM via BMN truncation and S-Duality
Abhijit Gadde, Eunwoo Lee, Rajat Raj +1
The one-loop cohomology of N=4 SYM is conjectured to be isomorphic to the exact cohomology. As a result, its truncations are expected to be subrings of the exact cohomology. We stu…

Analysis of s-t symmetric classical S-matrices
Abhijit Gadde, Shraiyance Jain
We analyze the complex analytic properties of Classical (tree-level) S-matrices for four scalar particles with s-t crossing symmetry, involving an infinite number of exchanges. Und…
