Controlling Atom-Photon Bound States in an Array of Josephson-Junction Resonators

2022

Engineering the electromagnetic environment of a quantum emitter gives rise to a plethora of exotic light -matter interactions. In particular, photonic lattices can seed long-lived atom-photon bound states inside photonic band gaps. Here, we report on the concept and implementation of a novel microwave architecture consisting of an array of compact superconducting resonators in which we have embedded two frequency -tunable artificial atoms. We study the atom-field interaction and access previously unexplored coupling regimes, in both the single-and double-excitation subspace. In addition, we demonstrate coherent interactions between two atom-photon bound states, in both resonant and dispers…

Experimental Engineering of Arbitrary Qudit States with Discrete-Time Quantum Walks

2019

The capability to generate and manipulate quantum states in high-dimensional Hilbert spaces is a crucial step for the development of quantum technologies, from quantum communication to quantum computation. One-dimensional quantum walk dynamics represents a valid tool in the task of engineering arbitrary quantum states. Here we affirm such potential in a linear-optics platform that realizes discrete-time quantum walks in the orbital angular momentum degree of freedom of photons. Different classes of relevant qudit states in a six-dimensional space are prepared and measured, confirming the feasibility of the protocol. Our results represent a further investigation of quantum walk dynamics in p…

Processing and effectiveness of formative feedback to increase comprehension and learning of conceptual knowledge in digital environments

2019

Los estudiantes de educación secundaria participan diariamente en tareas académicas diseñadas para desarrollar habilidades de lectura y facilitar la adquisición de conocimientos. Habitualmente, los docentes suelen pedir a sus estudiantes que lean textos expositivos y respondan preguntas sobre sus contenidos (e.g., Ness, 2011; Sánchez y García, 2015; Sánchez, García y Rosales, 2010), ya que estas tareas respaldan la comprensión y el aprendizaje de conceptos e ideas (e.g., Anmarkrud, McCrudden, Bråten y Strømsø, 2013; Cerdán, Gilabert y Vidal-Abarca, 2011; Lewis y Mensink, 2012; Roelle y Berthold, 2017). En estas situaciones, los estudiantes han de aplicar tanto procesos cognitivos de compres…

Molecular Mechanisms of the Blockage of Glioblastoma Motility

2021

Glioblastoma (GBM) is the most common and lethal brain tumor. GBM has a remarkable degree of motility and is able to infiltrate the healthy brain. In order to perform a rationale-based drug-repositioning study, we have used known inhibitors of two small Rho GTPases, Rac1 and Cdc42, which are upregulated in GBM and are involved in the signaling processes underlying the orchestration of the cytoskeleton and cellular motility. The selected inhibitors (R-ketorolac and ML141 for Cdc42 and R-ketorolac and EHT 1864 for Rac1) have been successfully employed to reduce the infiltration propensity of GBM in live cell imaging studies. Complementarily, all-atom simulations have elucidated the molecular …

Generalized wave propagation problems and discrete exterior calculus

2018

We introduce a general class of second-order boundary value problems unifying application areas such as acoustics, electromagnetism, elastodynamics, quantum mechanics, and so on, into a single framework. This also enables us to solve wave propagation problems very efficiently with a single software system. The solution method precisely follows the conservation laws in finite-dimensional systems, whereas the constitutive relations are imposed approximately. We employ discrete exterior calculus for the spatial discretization, use natural crystal structures for three-dimensional meshing, and derive a “discrete Hodge” adapted to harmonic wave. The numerical experiments indicate that the cumulat…

Current Social and Rangeland Access Trends among Pastoralists in the Western Algerian Steppe

2021

International audience; In the western Algerian steppe, the public authorities have carried out actions aimed at rural development (agricultural development programs) and combating desertification (grazing reserves) to counter the significant and rapid loss of vegetation cover of pastures by overgrazing, and the consequent impacts on local livelihoods. In the Rogassa area, these actions have impacted land tenure and the ancestral and collective way of land use and access. These changes have caused transformations in lifestyle and pasture management. This research aims to characterize how such changes are affecting local pastoralists and what their perceptions are about them. A selective sam…

Reputation and financial reporting in Finnish public organizations

2021

PurposeThis article analyzes the links between financial reports and reputation in the context of Finnish public sector organizations. In general, the paper discusses the accounting treatment of intangible and tangible assets and the quality and relevance of public sector financial reporting.Design/methodology/approachFor data, we combine three data sets: financial statement information of eight anonymous Finnish public organizations, the results of a reputation survey among their key stakeholders (N = 914) and a sample of the social media sentiment around the organizations.FindingsOur findings suggest that a decrease in spending and, surprisingly in the nonprofit sector, an increase in the…

Rédiger pour être publié ! 2e édition 2012

2012

Publish or perish. This saying clearly exemplifies that science communication is vital for scientists, research bodies and nation competitiveness. Nowadays both computers and internet have deeply changed the way scientific articles are written and published. In an editorial world moving at accelerated pace, scientists are eager to get their papers published in the best journals because impact factors are ruling careers and funding. Since fundings are provided by various public and private bodies, scientific papers should be partly understandable by a wide audience from journalists to entrepreneurs, political leaders and the general public. However, as an editor of scientific journals, I obs…
