Phase-space descriptions of operators and the Wigner distribution in quantum mechanics II. The finite dimensional case
S. Chaturvedi, E. Ercolessi, G. Marmo +3
A complete solution to the problem of setting up Wigner distribution for N-level quantum systems is presented. The scheme makes use of some of the ideas introduced by Dirac in the…
Phase-space descriptions of operators and the Wigner distribution in quantum mechanics I. A Dirac inspired view
S. Chaturvedi, E. Ercolessi, G. Marmo +3
Drawing inspiration from Dirac's work on functions of non commuting observables, we develop a fresh approach to phase space descriptions of operators and the Wigner distribution in…
Necessary and Sufficient Classicality Conditions on Photon Number Distributions
R. Simon, Mary Selvadoray, Arvind +1
We exploit results on the classical Stieltjes moment problem to obtain completely explicit necessary and sufficient conditions for the photon number distribution p(n) of a radiatio…
Nonclassicality and the concept of local constraints on the photon number distribution
R. Simon, Mary Selvadoray, Arvind +1
We exploit results from the classical Stieltjes moment problem to bring out the totality of all the information regarding phase insensitive nonclassicality of a state as captured b…
Moments of the Wigner Distribution and a Generalized Uncertainty Principle
R. Simon, N. Mukunda
The nonnegativity of the density operator of a state is faithfully coded in its Wigner distribution, and this places constraints on the moments of the Wigner distribution. These co…
