Euclidean systems include poly- and monochromatic wide-angle optics, acoustics, and also infinite discrete data sets. We use a recently defined Wigner operator and (quasiprobability) distribution function to set up and study the phase-space evolution of these models, subject to differential and difference equations, respectively. Infinite data sets and two- dimensional monochromatic (Helmholtz) fields are thus shown by their Wigner function on a cylinder of (2 ) direction and location; the…

Position and momentum bases for the monochromatic Maxwell fish-eye and the sphere

In geometric optics the Maxwell fish-eye is a medium where light rays follow circles, while in scalar wave optics this medium can only ‘trap’ fields of certain discrete frequencies. In the

Wigner functions for Helmholtz wave fields

We investigate a general form of the Wigner function for wave fields that satisfy the Helmholtz equation in two-dimensional free space. The momentum moment of this Wigner function is shown to

Finite Hamiltonian systems on phase space

We construct and analyze a Hamiltonian system whose position coordinate takes values on the finite subset of contiguous integers Zj := {−j,−j+1, . . . , j}, with the purpose of applying the resulting

Linear transformations and aberrations in continuous and finite systems

In geometric optics there is a natural distinction between the paraxial and aberration regimes, which contain respectively the linear and nonlinear canonical transformations of position and momentum

Wigner functions for the pair angle and orbital angular momentum

The problem of constructing physically and mathematically well-defined Wigner functions for the canonical pair angle and angular momentum is solved. While a key element for the construction of Wigner

Finite optical Hamiltonian systems

In this essay we finitely quantize the Hamiltonian system of geometric optics to a finite system that is also Hamiltonian, but where signals are described by complex N-vectors, which are subject to

Finite Hamiltonian systems: Linear transformations and aberrations

Finite Hamiltonian systems contain operators of position, momentum, and energy, having a finite number N of equally-spaced eigenvalues. Such systems are under the æis of the algebra su(2), and their

TLDR
The Kravchuk coherent states provided by the finite oscillator model are used to evince the nonlinear transformations that elliptic-profile waveguides produce on phase space by means of the SO(3) Wigner function.

Wigner distributions and quantum mechanics on Lie groups: The case of the regular representation

We consider the problem of setting up the Wigner distribution for states of a quantum system whose configuration space is a Lie group. The basic properties of Wigner distributions in the familiar

Elements of euclidean optics

Euclidean optics are models of the manifold of rays and wavefronts in terms of coset spaces of the Euclidean group. One realization of this construction is the geometric model of Hamilton's optical

The behavior of any system at high enough temperatures approaches that of its classical counterpart. The probability of any configurational position is then proportional to exp—U/kT, with U the

Invariant inner products on spaces of solutions of the Klein–Gordon and Helmholtz equations

We construct sesquilinear forms which are invariant under the similarity groups of the Klein–Gordon and Helmholtz equations. These give rise to positive definite inner products on subspaces of

Representation of Lie groups and special functions

At first only elementary functions were studied in mathematical analysis. Then new functions were introduced to evaluate integrals. They were named special functions: integral sine, logarithms, the
