Monotones from multi-invariants: a classification
Abhijit Gadde, Shraiyance Jain
In this paper we study local unitary invariants of a multi-partite quantum state that are monotonic, on average, under local operations and classical communication (locc). In parti…

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…
