Detecting quantum many-body states with imperfect measuring devices
K. Uriostegui, C. Pineda, C. Chryssomalakos +2
We study a coarse-graining map arising from incomplete and imperfect addressing of particles in a multipartite quantum system. In its simplest form, corresponding to a two-qubit st…
Unitary transformation approach to the paraxial wave equation
M. Huerta-Sandoval, K. Uriostegui, I. Ramos-Prieto +2
We present a framework for the paraxial wave equation based on propagation-dependent unitary transformations closely related to the Lewis-Ermakov invariant. This approach establish…
Mathieu-Bragg photonic lattices
I. Ramos-Prieto, K. Uriostegui, J. Récamier +2
We show that Bragg diffraction may be modeled by classical light propagation in photonic lattices having a square power law for the refraction index coefficient. The dynamics is sh…
Discrete Bessel and Mathieu functions
Kenan Uriostegui, Kurt Bernardo Wolf
The two-dimensional Helmholtz equation separates in elliptic coordinates based on two distinct foci, a limit case of which includes polar coordinate systems when the two foci coale…
Discrete Bessel functions and transform
Kenan Uriostegui, Kurt Bernardo Wolf
We present a straightforward discretization of the Bessel functions to discrete counterparts , of integer orders on integer points $x_m \equiv…
