Quantum phases of a qutrit
A. B. Klimov, L. L. Sanchez-Soto, H. de Guise +1
We consider various approaches to treat the phases of a qutrit. Although it is possible to represent qutrits in a convenient geometrical manner by resorting to a generalization of…
Optimizing omnidirectional reflection by multilayer mirrors
T. Yonte, J. J. Monzon, A. Felipe +1
Periodic layered media can reflect strongly for all incident angles and polarizations in a given frequency range. Quarter-wave stacks at normal incidence are commonplace in the des…
Inequivalent classes of closed three-level systems
Andre B. Klimov, Hubert de Guise, Luis L. Sanchez-Soto
We show here that the and V configurations of three-level atomic systems, while they have recently been shown to be equivalent for many important physical quantities when drive…
A measurable entanglement criterion for two qubits
Hoshang Heydari, Gunnar Björk, Luis Sánchez-Soto
We propose a directly measurable criterion for the entanglement of two qubits. We compare the criterion with other criteria, and we find that for pure states, and some mixed states…
General unit-disk representation for periodic multilayers
Alberto G. Barriuso, Juan J. Monzon, Luis L. Sanchez-Soto
We suggest a geometrical framework to discuss periodic layered structures in the unit disk. The band gaps appear when the point representing the system approaches the unit circle.…
Hyperbolic reflections as fundamental building blocks for multilayer optics
A. G. Barriuso, J. J. Monzon, L. L. Sanchez-Soto +1
We reelaborate on the basic properties of lossless multilayers by using bilinear transformations. We study some interesting properties of the multilayer transfer function in the un…
Characterizing the reflectance of periodic layered media
J. J. Monzon, T. Yonte, L. L. Sanchez-Soto
It has recently been shown that periodic layered media can reflect strongly for all incident angles and polarizations in a given frequency range. The standard treatment gets these…
