Local sampling of the SU(1,1) Wigner function
N. Fabre, A. B. Klimov, G. Leuchs +1
Despite the indisputable merits of the Wigner phase-space formulation, it has not been widely explored for systems with SU(1,1) symmetry, as a simple operational definition of the…
From polarization multipoles to higher-order coherences
Aaron Z. Goldberg, Andrei B. Klimov, Hubert de Guise +3
We demonstrate that the multipoles associated with the density matrix are truly observable quantities that can be unambiguously determined from intensity moments. Given their corre…
Semi-Classical Discretization and Long-Time Evolution of Variable Spin Systems
Giovani E. Morales-Hernández, Juan C. Castellanos, José L. Romero +1
We apply the semi-classical limit of the generalized map for representation of variable-spin systems in a four-dimensional symplectic manifold and approximate their evoluti…
Effective and efficient resonant transitions in periodically modulated quantum systems
Isabel Sainz, Andrés García, Andrei B. Klimov
We analyse periodically modulated quantum systems with and symmetries. Transforming the Hamiltonian into the Floquet representation we apply the Lie transformatio…
MUB-like structures and tomographic reconstruction for N-ququart systems
Juan Díaz-Guevara, Isabel Sainz, Andrei B. Klimov
We construct an informationally complete set of mutually unbiased - like bases for N ququarts. These bases are used in an explicit tomographic protocol which performance is analyze…
Truncated Wigner approximation as a non-positive Kraus map
A. B. Klimov, I. Sainz, J. L. Romero
We show that the Truncated Wigner Approximation developed in the flat phase-space is mapped into a Lindblad-type evolution with an indefinite metric in the space of linear operator…
