On genuine multipartite entanglement signals
Abhijit Gadde
We give a general construction of genuinely multipartite entanglement signals from families of lower-partite symmetric local-unitary invariants satisfying a natural compatibility c…

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: 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…
