Multi-invariants in stabilizer states
Sriram Akella, Abhijit Gadde, Jay Pandey
Multipartite entanglement is a natural generalization of bipartite entanglement, but is relatively poorly understood. In this paper, we develop tools to calculate a class of multip…
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…
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…
Multi-invariants and Bulk Replica Symmetry
Abhijit Gadde, Jonathan Harper, Vineeth Krishna
In this paper, we analyze the question of replica symmetry in the bulk for multi-partite entanglement measures in the vacuum state of two dimensional holographic CFTs. We first def…
