Analyser les sports de nature : de l'ordre local au réseau.

Ce chapitre présente deux conceptions de l'analyse organisationnelle, au sens large (Friedberg, 1933 ; Latour, 2006) appliquées aux sports de nature. Il discute de leur pertinence théorique et empirique à partir d'exemples de travaux réalisés grâce à ces deux cadres théoriques. Il conclut en mettant en évidence les liens entre le contexte étudié, la " focale recherchée " et le choix de l'une de ces deux théories

Connecting the one-band and three-band Hubbard models of cuprates via spectroscopy and scattering experiments

The one-band and three-band Hubbard models which describe the electronic structure of cuprates indicate very different values of effective electronic parameters (EPs), such as the Cu on-site Coulomb energy and the Cu-O hybridization strength. In contrast, a comparison of EPs of several cuprates with corresponding values from spectroscopy and scattering experiments indicates similar values in the three-band model and cluster model calculations used to simulate experimental results. To explore this relation in detail, a Cu$_2$O cluster model calculation was carried out to obtain an expression for the Heisenberg exchange coupling $J$ between Cu sites using a downfolding method, taking into account Cu and O on-site correlations ($U_d$ and $U_p$), the charge-transfer energy $\Delta$ and the hopping $t$ between Cu and O sites. A quantitative analysis provides a consistent description of $J$ from neutron scattering experiments, using the three-band model and spectroscopic EPs. In addition, $J$ can be expressed in the one-band Hubbard model form with $\tilde{U}$ and $\tilde{t}$, which denote renormalized $U$ and $t$ using $\Delta$ and $U_p$, and their values indicate a large $\tilde{U}/\tilde{t}$, in agreement with reported values. The large $\tilde{U}/\tilde{t}$ arising from a combination of $U_d$, $U_p$ and $\Delta$ is thus hidden in the effective one-band Hubbard model. The ground-state singlet weights obtained from an exact diagonalization show the importance of the Cu-O Zhang-Rice singlet in the effective one-band Hubbard model. The results provide a consistent method to connect EPs obtained from spectroscopy and the three-band model with values of $J$ obtained from scattering experiments, band dispersion measurements and the effective one-band Hubbard model.Comment: 9 pages, 2 figures (submitted to Physical Review B

Atomic and Electronic Structure of a Rashba pp-nn Junction at the BiTeI Surface

The non-centrosymmetric semiconductor BiTeI exhibits two distinct surface terminations that support spin-split Rashba surface states. Their ambipolarity can be exploited for creating spin-polarized $p$-$n$ junctions at the boundaries between domains with different surface terminations. We use scanning tunneling microscopy/spectroscopy (STM/STS) to locate such junctions and investigate their atomic and electronic properties. The Te- and I-terminated surfaces are identified owing to their distinct chemical reactivity, and an apparent height mismatch of electronic origin. The Rashba surface states are revealed in the STS spectra by the onset of a van Hove singularity at the band edge. Eventually, an electronic depletion is found on interfacial Te atoms, consistent with the formation of a space charge area in typical $p$-$n$ junctions.Comment: 5 pages, 4 figure
