Space QUEST mission proposal: experimentally testing decoherence due to gravity
(IOP Science, 2018-06-12)
Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum correlations, such as entanglement, may exhibit different behavior to purely classical ...

A three-dimensional model for the dispersion of radioactive substances in marine ecosystems: application to the Baltic Sea after the Chernobyl disaster
(Elsevier, 2004)
A 3-D dispersion model has been developed to simulate the dispersion of nuclear contaminants in marine ecosystems. This model is characterized by presenting high spatial resolution, by taking into account the possible ...

Introducción a la lógica cuántica
(Consejo Superior de Investigaciones Científicas, CSIC, 2000)
En este trabajo trataremos de responder las siguientes preguntas: 1. ¿Qué entendemos por «lógica» de una teoría física? 2. ¿Cuál es la lógica de la física clásica? 3. ¿Cómo se puede construir una lógica basada en la mecánica ...

Quantum key distribution in the Holevo limit
(American Physical Society, 2000-12-25)
A theorem by Shannon and the Holevo theorem impose that the efficiency of any protocol for quantum key distribution, E , defined as the number of secret (i.e., allowing eavesdropping detection) bits per transmitted bit ...

A method for the determination of counting efficiencies in gamma-spectrometric measurements with HPGe detectors
(Elsevier, 1996)
In this paper a general method for y-ray efficiency calibration is presented. The method takes into account the differences of densities and counting geometry between the real sample and the calibration sample. It is based ...

Low concentration CO2 capture in fluidized beds of Ca(OH)2 as affected by storage humidity
(Elsevier, 2020)
Carbon negative emission technologies (NETs) such as CO2 direct air capture (DAC) are being already considered as necessary for climate change mitigation. This paper investigates CO2 capture at room temperature and ...

Geometric vector potentials from nonadiabatic spin dynamics
(American Physical Society, 2017-07-27)
We propose a theoretical framework that captures the geometric vector potential emerging from the nonadiabatic spin dynamics of itinerant carriers subject to arbitrary magnetic textures. Our approach results in a series ...

Natural radionuclides (NORM) in a Moroccan river affected by former conventional metal mining activities
(Minería Sostenible, 2019-02)
The main aim of this work was to determine the levels of multiple natural radionuclides in an aquatic system(Moulouya river, Morocco) impacted by multiple abandoned Zinc and Lead mines.238U,234U,232Th,230Th and210Po were ...

Basic exclusivity graphs in quantum correlations
(American Physical Society, 2013)
A fundamental problem is to understand why quantum theory only violates some noncontextuality (NC) inequalities and identify the physical principles that prevent higher-than-quantum violations. We prove that quantum ...

Quantum nonlocality via local contextuality with qubit-qubit entanglement
(American Physical Society, 2016-04-28)
Quantum nonlocality can be revealed “via local contextuality” in qudit-qudit entangled systems with d > 2 , that is, through the violation of inequalities containing Alice-Bob correlations that admit a local description, ...
