La découverte de Qumrân : quelle importance pour l'étude du Nouveau Testament ?

Morgan, James

In: Les manuscrits de la mer Morte au lendemain de leur 70e anniversaire, 2019, p. 165-211

Depuis les découvertes des manuscrits de Qumrân (1947-1956), les chercheurs ne cessent d’explorer les nombreux parallèles entre les écrits de Qumrân et le Nouveau Testament (NT) et ce qu’ils laissent entrevoir des communautés qui les ont rédigés. Nous pouvons parler sans exagération d’une « fascination des chrétiens pour Qumrân ». Ainsi, comme dans toutes les sciences, les...

Luc-Actes : un tour de force littéraire et théologique

Morgan, James

In: Hokhma : revue de réflexion théologique, 2013, vol. 103, p. 9-29

L’étude de la Bible pour l’édification de l’Église reste la voie royale. L’Évangile selon Luc et les Actes des Apôtres représentent une partie importante du Nouveau Testament qu’il vaut la peine d’exploiter. Ces deux livres, qui devaient avoir, à l’origine, la forme de deux grands rouleaux adressés à Théophile, occupent cinquante-deux chapitres dans nos Bibles actuelles....

How network topologies impact project alliance performance: evidence from the movie industry

Zhang, Xin-Jie ; Tang, Yong ; Xiong, Jason ; Wang, Wei-Jia ; Zhang, Yi-Cheng

In: Entropy, 2019, vol. 21, no. 9, p. 859

In many industries, partners are interconnected in project alliances that have limited lifespans and clearly-defined boundaries. The transparency of the movie industry provides a unique opportunity to study how alliance network topologies impact the performance of project alliances from the perspectives of social networks and organization theories. In this work, we compiled a massive movie...

Computational socioeconomics

Gao, Jian ; Zhang, Yi-Cheng ; Zhou, Tao

In: Physics Reports, 2019, vol. 817, p. 1–104

Uncovering the structure of socioeconomic systems and timely estimation of socioeconomic status are significant for economic development. The understanding of socioeconomic processes provides foundations to quantify global economic development, to map regional industrial structure, and to infer individual socioeconomic status. In this review, we will make a brief manifesto about a new ...

Hund excitations and the efficiency of Mott solar cells

Petocchi, Francesco ; Beck, Sophie ; Ederer, Claude ; Werner, Philipp

In: Physical Review B, 2019, vol. 100, no. 7, p. 075147

We study the dynamics of photoinduced charge carriers in semirealistic models of LaVO3 and YTiO3 polar heterostructures. It is shown that two types of impact ionization processes contribute to the carrier multiplication in these strongly correlated multiorbital systems: The first mechanism involves local spin state transitions, while the second mechanism involves the scattering of...

Entropy-cooled nonequilibrium states of the Hubbard model

Werner, Philipp ; Li, Jianju ; Golež, Denis ; Eckstein, Martin

In: Physical Review B, 2019, vol. 100, no. 15, p. 155130

We show that the recently proposed cooling-by-doping mechanism allows one to efficiently prepare interesting nonequilibrium states of the Hubbard model. Using nonequilibrium dynamical mean field theory and a particle-hole symmetric setup with dipolar excitations to full and empty bands we produce cold photodoped Mott insulating states with a sharp Drude peak in the optical conductivity, a ...

Accounting for effective interactions among charged microgels

Aguirre-Manzo, L. A. ; Ledesma-Motolinía, Mónica ; Rojas-Ochoa, Luis Fernando ; Trappe, Véronique ; Callejas-Fernández, J. ; Haro-Pérez, Catalina ; González-Mozuelos, P.

In: Physical Review E, 2019, vol. 100, no. 3, p. 032602

We introduce a theoretical approach to describe structural correlations among charged permeable spheres at finite particle concentrations. This theory explicitly accounts for correlations among microions and between microions and macroions and allows for the proposal of an effective interaction among macroions that successfully captures structural correlations observed in poly- N -isopropyl...

Light induced inverse-square law interactions between nanoparticles: “mock gravity” at the nanoscale

Luis-Hita, J. ; Marqués, M. I. ; Delgado-Buscalioni, R. ; Sousa, N. de ; Froufe-Pérez, L. S. ; Scheffold, Frank ; Sáenz, J. J.

In: Physical Review Letters, 2019, vol. 123, no. 14, p. 143201

The interaction forces between identical resonant molecules or nanoparticles, optically induced by a quasimonochromatic isotropic random light field, are theoretically analyzed. In general, the interaction force exhibits a far-field oscillatory behavior at separation distances larger than the light wavelength. However, we show that the oscillations disappear when the frequency of the random...

From chaos to many-body localization: some introductory notes

Chotorlishvili, L. ; Stagraczyński, S. ; Schüler, Michael ; Berakdar, J.

In: Acta Physica Polonica A, 2019, vol. 135, no. 6, p. 1155–1162

Staring from the kicked rotator as a paradigm for a system exhibiting classical chaos, we discuss the role of quantum coherence resulting in dynamical localization in the kicked quantum rotator. In this context, the disorder-induced Anderson localization is also discussed. Localization in interacting, quantum many-body systems (many-body localization) may also occur in the absence of...
