We elucidate the dependence of purity and entanglement of two-photon states generated by spontaneous parametric down-conversion on the parameters of the source, such as crystal length, pump beam divergence, frequency ...

The two-body Coulomb problem with sources is studied. Close d form solutions are provided for particular non-homogeneities used within the J-matrix method. The results are employed to build analytical solutions having ...

This article is devoted to the study of two arithmetical sources associated with classical partitions, that are both defined through the mediant of two fractions. The Stern-Brocot source is associated with the sequence of ...

The current work is a climatological study and characterization of the global sources of moisture for continental precipitation based on a Lagrangian analysis technique. It consists of a synopsis of a series of articles ...

In this paper, we explore the three-node multi-terminal lossy source coding problem, which seems to offer a formidable mathematical complexity. We derive an inner bound to the general rate-distortion region of this problem, ...

The two-body Coulomb Schrödinger equation with different types of nonhomogeneities are studied. The particular solution of these nonhomogeneous equations is expressed in closed form in terms of a two-variable hypergeometric ...
