Quantum Simulation Of The Quantum Rabi Model In A Trapped Ion
(American Physical Society, 2018-04-30)The quantum Rabi model, involving a two-level system and a bosonic field mode, is arguably the simplest and most fundamental model describing quantum light-matter interactions. Historically, due to the restricted parameter ... -
Quantum simulations of relativistic quantum physics in circuit QED
(IOP Publishing, 2013-06)We present a scheme for simulating relativistic quantum physics in circuit quantum electrodynamics. By using three classical microwave drives, we show that a superconducting qubit strongly coupled to a resonator field mode ... -
Quantum Simulator for Transport Phenomena in Fluid Flows
(Nature Publishing Group, 2015-08-17)Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we develop a quantum simulator based on ... -
Quantum size effects of Pb overlayers at high coverages.
(Elsevier, 2007-07-18)We have studied Pb thin films as a function of the thickness up to 60 monolayers (MLs) using ab initio first principles and model calculations. Magic heights corresponding to a modulated oscillatory pattern of the energy ... -
Quantum structural fluxion in superconducting lanthanum polyhydride
(Nature Communications, 2023-03-25)The discovery of 250-kelvin superconducting lanthanum polyhydride under high pressure marked a significant advance toward the realization of a room‐temperature superconductor. X-ray diffraction (XRD) studies reveal a ... -
Quantum work statistics, Loschmidt echo and information scrambling
(Nature Publishing, 2018-08-22)A universal relation is established between the quantum work probability distribution of an isolated driven quantum system and the Loschmidt echo dynamics of a two-mode squeezed state. When the initial density matrix is ... -
Quantum-enhanced Doppler lidar
(Nature, 2022-12)We propose a quantum-enhanced lidar system to estimate a target’s radial velocity, which employs squeezed and frequency-entangled signal and idler beams. We compare its performance against a classical protocol using a ... -
Quantum-Gravitational Effects on Primordial Power Spectra in Slow-Roll Inflationary Models
(MDPI, 2018-01-08)We review the computation of the power spectra of inflationary gauge-invariant perturbations in the context of canonical quantum gravity for generic slow-roll models. A semiclassical approximation, based on an expansion ... -
Quantum-Size Effects in Ultra-Thin Gold Films on Pt(111) Surface
(MDPI, 2023-12-22)We calculate, within the density-functional theory, the atomic and electronic structure of the clean Pt(111) and Au(111) surfaces and the nML-Au/Pt(111) systems with n varying from one to three. The effect of the spin–orbital ... -
Quartz chemistry of granitic pegmatites: Implications for classification, genesis and exploration
(Elsevier, 2021-12-05)[EN]Quartz from 254 pegmatites representing eight pegmatite fields and provinces worldwide was investigated by laser-ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) to determine concentrations of trace ... -
Quartzite Procurement in Conglomerates and Deposits: Geoarchaeological Characterization of Potential Catchment Areas in the Central Part of the Cantabrian Region, Spain
(Wiley, 2021-05)Raw material characterization in Paleolithic archaeology has widened our knowledge of Middle Paleolithic societies. Procurement of raw material, specifically flint, has allowed the tracing of the mobility of both stones ... -

El que se sirve de un animal
(IDIBE, 2023-11-02)El artículo 1905 del Código Civil dispone que el poseedor de un animal, o el que se sirve de él, es responsable de los perjuicios que causare. El trabajo aborda el análisis de esta responsabilidad alternativa para centrarse ... -
"Las que tienen que servir" y las servidas. La evolución del servicio doméstico en el franquismo y la construcción de la subjetividad femenina
(Universidad Autónoma de Madrid, 2013)Uno de los personajes femeninos más comunes del cine español desde la década de los cincuenta hasta mediados de los setenta fue la “chacha”. La explicación a este fenómeno la hayamos en que el servicio doméstico, que ... -

Query-by-Example Spoken Term Detection ALBAYZIN 2012 evaluation: overview, systems, results, and discussion
(Springer, 2013-09)Query-by-Example Spoken Term Detection (QbE STD) aims at retrieving data from a speech data repository given an acoustic query containing the term of interest as input. Nowadays, it has been receiving much interest due to ... -
Quest for the Most Aromatic Pathway in Charged Expanded Porphyrins
(Wiley, 2023-01)Despite the central role of aromaticity in the chemistry of expanded porphyrins, the evaluation of aromaticity remains difficult for these extended macrocycles. The presence of multiple conjugation pathways and different ... -
Question particles in Basque
(Universitat Autònoma de Barcelona, 2019)This article proposes separate analyses for the question particles -a and al in Basque, which occur only in polarity questions, within the framework of Generative Grammar. I will propose that the former one, used in the ... -
¿Qué hipótesis formulan y en qué las basan los estudiantes de Grado de Educación Primaria al analizar la formación de un diapiro?
(Asociación Española Para la Enseñanza de las Ciencias de la Tierra, 2020)Existe un amplio consenso en el campo de la didáctica de la ciencia respecto a la necesidad de integrar en el aula las grandes ideas científicas con las prácticas propias de esta. Una de tales prácticas es el uso de ... -
