Space-weather disturbances can disrupt radio communications, navigation, defense, spacecraft operations and modern critical technological systems, making reliable characterization of the near-Earth response to solar activity important. Distributed magnetometer networks continuously monitor this environment, but heterogeneous data quality, local observing conditions, and station-by-station...
We present an analytical method for determining the quarter-half-quarter (QHQ) wave-plate settings required to implement a prescribed $\mathrm{U}(2)$ polarization transformation, up to a physically irrelevant global phase. The method addresses the inverse problem in which the desired operation is specified as a unitary matrix rather than by Euler angles or optical-element orientations. By...
Parallel plates immersed into a system have helped to understand fundamental concepts in Physics, such as the Casimir effect and the Fabry-Perot interferometer. Motivated by these phenomena, we consider films with a SISIS structure, where S and I represent superconducting and insulating layers, respectively. We find a novel kind of resonance promoted by the normal layers that play the role of...
Usando la tabla de masas AME 2020, se calcula la energía disponible de las reacciones de la fisión inducida por neutrones térmicos de los núcleos físiles 233U, 235U y 239Pu, respectivamente. Con valores experimentales obtenidos por otros autores, calculamos los máximos de energía cinética total de las parejas de fragmentos complementarios. Con esos valores se calcula la energía de excitación...
