Applying the Kolmogorov–Zurbenko filter followed by random forest models to 7Be observations in Spain (2006–2021)
(Elsevier, 2024-05)n this study, we analysed 7Be weekly surface measurements from six Spanish laboratories from 2006 to 2021. The Kolmogorov–Zurbenko filter was applied to the six 7Be time series, and following an iterative process, the ... -
Approach to scaling in axion string networks
(APS, 2021-05-26)We study the approach to scaling in axion string networks in the radiation era, through measuring the root-mean-square velocity v as well as the scaled mean string separation x. We find good evidence for a fixed point in ... -

(2021-07-12)En la tesis se estudia la radiación gravitatoria y la estructura del infinito desde un punto de vista geométrico, dentro del contexto de la Relatividad General de Einstein. En particular, se emplean compactificaciones ... -
Atomistic simulation on the nucleation of C-S-H.
(2023-05-12)En este trabajo, hemos utilizado métodos computacionales para estudiar las primeras etapas de la nucleación del C-S-H a escala atómica. El cemento es el material de construcción más utilizado en el mundo, y el gel C-S-H ... -
Beyond the infrared: a centenary of Heinrich Rubens's death
(Springer, 2022)Heinrich Rubens (Wiesbaden, 1865, Berlin, 1922) was the first scientist to study the large gap between the conventional infrared range and the electrical wave regime, better known today as the terahertz gap. To this end, ... -
Biochemical and Metabolomic Changes after Electromagnetic Hyperthermia Exposure to Treat Colorectal Cancer Liver Implants in Rats
(MDPI, 2021-05-17)Background: Hyperthermia (HT) therapy still remains relatively unknown, in terms of both its biological and therapeutic effects. This work aims to analyze the effects of exposure to HT, such as that required in anti-tumor ... -
Brane nucleation in supersymmetric models
(Springer Nature, 2023-10-11)This paper explores the process of vacuum decay in supersymmetric models related to flux compactifications. In particular, we describe these instabilities within supersymmetric Lagrangians for a single three-form multiplet. ... -
Canonical quantization of superconducting circuits
(2021-03-30)Los circuitos superconductores han surgido como una de las implementaciones físicas más prometedorasen tecnologías cuánticas, fusionando la física, la ingeniería y las matemáticas. Esta tesis expone modeloshamiltonianos ... -
Cellular patterns and dry convection in textured dust storms at the edge of Mars North Polar Cap
(Elsevier, 2022-11)We present a study of textured local dust storms that develop at the northern polar cap boundary on Mars springtime. We have used images obtained with VMC and HRSC cameras onboard Mars Express and MARCI on MRO to analyze ... -
Changes in the simulation of atmospheric instability over the Iberian Peninsula due to the use of 3DVAR data assimilation
(Copernicus Publications, 2021-06-18)[EN] Abstract. The ability of two downscaling experiments to correctly simulate thermodynamic conditions over the Iberian Peninsula (IP) is compared in this paper. To do so, three parameters used to evaluate the unstable ... -
Chiral torsional effects in anomalous fluids in thermal equilibrium
(Scuola Internazionale Superiore di Studi Avanzati (SISSA) ; Springer Verlag, 2021-05-24)[EN] Using the similarity between spacetime torsion and axial gauge couplings, we study torsional contributions to the equilibrium partition function in a stationary background. In the case of a charged fluid minimally ... -
CMIP6 projections for global offshore wind and wave energy production (2015–2100)
(Nature, 2023-10)Three-hourly CMIP6 projections have been used in conjuction with the CSIRO WaveWatchIII wave model to calculate the global trends in offshore wind and wave energy for the SSP585 and SSP126 scenarios until 2100. The results ... -
Coexistence of Superconductivity and Spin-Splitting Fields in Superconductor/Ferromagnetic Insulator Bilayers of Arbitrary Thickness
(American Physical Society, 2021-05-19)Ferromagnetic insulators (FI) can induce a strong exchange field in an adjacent superconductor (S) via the magnetic proximity effect. This manifests as spin splitting of the BCS density of states of the superconductor, an ... -
Collective and non-collective molecular dynamics in a ferroelectric nematic liquid crystal studied by broadband dielectric spectroscopy
(AIP, 2023-10-23)A great deal of effort has been recently devoted to the study of dielectric relaxation processes in ferroelectric nematic liquid crystals, yet their interpretation remains unclear. In this work, we present the results of ... -
