Many-body entanglement in fermion systems
N. Gigena, M. Di Tullio, R. Rossignoli
We introduce a general bipartite-like representation and Schmidt decomposition of an arbitrary pure state of indistinguishable fermions, based on states of and fe…
Spacetime Quantum Actions
N. L. Diaz, J. M. Matera, R. Rossignoli
We propose a formulation of quantum mechanics in an extended Fock space in which a tensor product structure is applied to time. Subspaces of histories consistent with the dynamics…
Nonlinear effects on the dynamics of quantum harmonic modes coupled through angular momentum
N. Canosa, R. Rossignoli, Javier Garcia +2
We investigate nonlinear effects on the dynamics of entanglement and other quantum observables in a system of two harmonic modes coupled through angular momentum. The nonlinearity…
One-body entanglement as a quantum resource in fermionic systems
N. Gigena, M. Di Tullio, R. Rossignoli
We show that one-body entanglement, which is a measure of the deviation of a pure fermionic state from a Slater determinant (SD) and is determined by the mixedness of the single-pa…
