Distinguishing Majorana Zero Modes from Impurity States through Time-Resolved Transport
2019
We study time-resolved charge transport in a superconducting nanowire using time-dependent Landauer-B{\"u}ttiker theory. We find that the steady-state Majorana zero-bias conductance peak emerges transiently accompanied by characteristic oscillations after a bias-voltage quench. These oscillations are absent for a trivial impurity state that otherwise shows a very similar steady-state signal as the Majorana zero mode. In addition, we find that Andreev bound states or quasi-Majorana states in the topologically trivial bulk phase can give rise to a zero-bias conductance peak, also retaining the transient properties of the Majorana zero mode. Our results imply that (1) time-resolved transport m…
Ultrathin Films of 2D Hofmann-Type Coordination Polymers: Influence of Pillaring Linkers on Structural Flexibility and Vertical Charge Transport
2019
Searching for novel materials and controlling their nanostructuration into electronic devices is a challenging task ahead of chemists and chemical engineers. Even more so when this new application requires an exquisite control over the morphology, crystallinity, roughness and orientation of the films produced. In this context, it is of critical importance to analyze the influence of the chemical composition of perspective materials on their properties at the nanoscale. We report the fabrication of ultrathin films (thickness < 30 nm) of a family of FeII Hofmann-like coordination polymers by using an optimized liquid phase epitaxy (LPE) set-up. The series [Fe(L)2{Pt(CN)4}] (L = pyridine, pyri…
Creencias y actitudes hacia la hipnosis de los psicólogos españoles
2009
El objetivo de este estudio es analizar las creencias y actitudes hacia la hipnosis de los colegiados para informar al Consejo General de Colegios Oficiales de Psicólogos de las necesidades de formación sobre hipnosis, así como analizar las respuestas en función de los Colegios de los participantes. Para ello se aplicó la Escala de Valencia de Actitudes y Creencias hacia la Hipnosis-Terapeuta a una muestra de 2.434 colegiados españoles. Los resultados indican que los colegiados que respondieron a la escala tienen, en general, creencias ajustadas sobre la hipnosis y una actitud positiva hacia la misma. No se encontraron diferencias entre los distintos COP en cuanto a creencias y actitudes ha…
Enseñar mindfulness: contextos de instrucción y pedagogía
2016
La aparición de mindfulness y su rápida diseminación en entornos clínicos obedece a diversas razones, siendo una de las más relevantes la relacionada con la pedagogía. La literatura científica ha propuesto un modelo de enseñanza de mindfulness basado en los mecanismos de eficacia, la configuración de nuevas demandas, y la aparición de diferentes contextos. El objetivo de este artículo es revisar por un lado los diferentes contextos de enseñanza de mindfulness (psicoeducativos, clínicos y espirituales), analizando las semejanzas y diferencias. A continuación se revisarán los mecanismos de eficacia (regulación de la atención, conciencia corporal, regulación emocional y cambios en la perspecti…
Confirmatory factor analysis of the Valencia scale on attitudes and beliefs toward hypnosis, therapist version
2008
Health professionals' beliefs and attitudes toward hypnosis may make them reluctant to use it or even to foster misapplications and iatrogenic uses of hypnosis. The Valencia Scale on Attitudes and Beliefs toward Hypnosis-Therapist version (VSABH-T) is a specific instrument to evaluate therapists' attitudes and beliefs. The aims of this study are to evaluate the 8-factor structure of the VSABH-T proposed from a confirmatory perspective. The sample comprised 1,661 licensed psychologists who are members of the Spanish Psychological Association for the initial test and 787 for the retest. Results confirmed the 8-factor structure obtained in a previous exploratory study, namely: Fear, Memory, He…
Análisis factorial exploratorio y propiedades psicométricas de la Escala de Valencia de Actitudes y Creencias hacia la Hipnosis, versión terapeuta
2006
La escasa competencia parental está relacionada con el desarrollo de un patrón de conducta desadaptativo en los/as hijos/as, con las consecuencias que este hecho conlleva. Sin embargo, prácticamente no existen pruebas que midan este constructo. La Escala de Competencia Parental Percibida (versión para padres/madres)(ECPP-p) está constituida por 22 items, que se estructuran en cinco factores. La ECPP presenta unas propiedades psicométricas altamente aceptables
Organotin(IV) azido and mixed azidothiocyanato complex anions; A Mössbauer and vibrational spectroscopic study
1975
Abstract Tetraphenylarsonium and tetramethylammonium salts of the complex anions Ph 3 Sn(N 3 ) − 2 , Ph 3 Sn(N 3 )(NCS) − , Me 2 Sn(N 3 ) 2− 4 and Ph 2 Sn(N 3 ) 2 (NCS) 2− 2 have been synthesized, and the solid state configuration of the complex anions has been studied by Mossbauer and vibrational spectroscopies. Trigonal bipyramidal structures are advanced for the Ph 3 Sn IV derivatives, with equatorial SnC 3 and apical pseudohalide ligands, while the R 2 Sn IV compounds are assumed to be trans -octahedral species. The NCS − ligands are observed to be N-bonded to Sn IV . Conductance and PMR (for the Me 2 Sn IV compound) data suggest the presence of the complex anions also in solution phase…

Dependence of thermal conductivity on structural parameters in porous samples
2012
The in-plane thermal conductivity of porous sintered bronze plates was studied both experimentally and numerically. We developed and validated an experimental setup, where the sample was placed in vacuum and heated while its time-dependent temperature field was measured with an infrared camera. The porosity and detailed three-dimensional structure of the samples were determined by X-ray microtomography. Lattice-Boltzmann simulations of thermal conductivity in the tomographic reconstructions of the samples were used to correct the contact area between bronze particles as determined by image analysis from the tomographic reconstructions. Small openings in the apparent contacts could not be de…
Radial phononic thermal conductance in thin membranes in the Casimir limit: Design guidelines for devices
2014
In a previous publication, we discussed the formalism and some computational results for phononic thermal conduction in the suspended membrane geometry for radial heat flow from a central source, which is a common geometry for some low-temperature detectors, for example. We studied the case where only diffusive surface scattering is present, the so called Casimir limit, which can be experimentally relevant at temperatures below $\sim$ 10 K in typical materials, and even higher for ultrathin samples. Here, we extend our studies to much thinner membranes, obtaining numerical results for geometries which are more typical in experiments. In addition, we interpret the results in terms of a small…
