Field Theory of the Gutzwiller Projection
Abhijat Sarma, Cenke Xu, Chong Wang
The Gutzwiller projection produces a well-known ansatz for spin-liquid and quantum Hall ground-state wavefunctions that is amenable to numerical simulation, with the Laughlin wavef…
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…
From Multipartite Entanglement to TQFT
Michele Del Zotto, Abhijit Gadde, Pavel Putrov
At long distances, a gapped phase of matter is described by a topological quantum field theory (TQFT). We conjecture a tight and concrete relationship between the genuine -p…
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…
