Quantum Fisher Information and multipartite entanglement in spin-1 chains
Federico Dell'Anna, Sunny Pradhan, Cristian Degli Esposti Boschi +1
In this paper, we study the ground state Quantum Fisher Information (QFI) in one-dimensional spin-1 models, as witness to Multipartite Entanglement. The models addressed are the Bi…

Hamiltonians and gauge-invariant Hilbert space for lattice Yang-Mills-like theories with finite gauge group
A. Mariani, S. Pradhan, E. Ercolessi
Motivated by quantum simulation, we consider lattice Hamiltonians for Yang-Mills gauge theories with finite gauge group, for example a finite subgroup of a compact Lie group. We sh…
