Separability and parity transitions in spin systems under nonuniform fields
N. Canosa, R. Mothe, R. Rossignoli
We examine the existence of completely separable ground states (GS) in finite spin- arrays with anisotropic couplings, immersed in a non-uniform magnetic field along one o…
History state formalism for scalar particles
N. L. Diaz, J. M. Matera, R. Rossignoli
We present a covariant quantum formalism for scalar particles based on an enlarged Hilbert space. The particular physical theory can be introduced through a timeless Wheeler DeWitt…
Fermionic entanglement in the Lipkin model
M. Di Tullio, R. Rossignoli, M. Cerezo +1
We examine the fermionic entanglement in the ground state of the fermionic Lipkin model and its relation with bipartite entanglement. It is first shown that the one-body entangleme…
Parallel-in-time optical simulation of history states
Dudbil Pabón, Lorena Rebón, Sebastián Bordakevich +5
We present an experimental optical implementation of a parallel-in-time discrete model of quantum evolution, based on the entanglement between the quantum system and a finite dimen…
