Induced sensitivity of Bacillus subtilis colony morphology to mechanical media compression
Published 2014-09-01“…Bacteria from several taxa, including Kurthia zopfii, Myxococcus xanthus, and Bacillus mycoides, have been reported to align growth of their colonies to small features on the surface of solid media, including anisotropies created by compression. While the function of this phenomenon is unclear, it may help organisms navigate on solid phases, such as soil. …”

Reconstructing the EFT of inflation from cosmological data
Published 2019-10-01“…Reconstructions of the primordial power spectrum (PPS) of curvature perturbations from cosmic microwave background anisotropies and large-scale structure data suggest that the usually assumed power-law PPS has localised features (up to $\sim 10\%$ in amplitude), although of only marginal significance in the framework of $\Lambda$CDM cosmology. …”

Persisting quantum effects in the anisotropic Rabi model at thermal equilibrium
Published 2024-01-01“…Recently, a continuous transition between the Jaynes-Cummings model and the Rabi model has been proposed by exploiting anisotropies in their light-matter interactions, known as the anisotropic quantum Rabi model. …”

Caractérisation d’échantillons représentatifs de soudures austénitiques en 316L par Spectroscopie de Résonance Ultrasonore (RUS)
Published 2023-09-01“…De nombreuses techniques reposant sur l’utilisation d’ondes élastiques ultrasonores ont déjà été mises en oeuvre afin d’obtenir avec précision les constantes élastiques et ainsi d’évaluer l’anisotropie apparente de ces milieux complexes. Dans le cadre de cette étude, la Spectroscopie de Résonance Ultrasonore (RUS) a été mise en oeuvre pour caractériser des échantillons prélevés dans un « mur » fabriqué par soudage dans l’hypothèse d’un comportement élastique orthotrope, homogène à l’échelle de l’échantillon. …”

The H0 tension in light of vacuum dynamics in the universe
Published 2017-11-01“…Recently the dispute came to the spotlight with renewed strength owing to the significant tension (at >3σ c.l.) between the latest Planck determination obtained from the CMB anisotropies and the local (distance ladder) measurement from the Hubble Space Telescope (HST), based on Cepheids. …”

Exploring the relationships between shear zones and granites: field and microstructural data for contrasting case studies of the Borborema Province (NE Brazil)
Published 2021-07-01“…Such characteristics are compatible with granites that were injected in the continental crust along planar anisotropies (i.e., shear zones) in the late-stage partial melting events that originated the migmatites of the area. …”

Horizon, homogeneity and flatness problems: do their resolutions really depend upon inflation?
Published 2024-04-01“…Without casting any aspersions on the inflationary theory, which after all is the most promising paradigm to explain the pattern of anisotropies observed in the cosmic microwave background, we argue that one cannot use homogeneity and flatness in support of inflation.…”

Killing the straw man: Does BICEP prove inflation at the GUT scale?
Published 2014-09-01“…We find that even without detailed considerations of the predicted BICEP signature of such a transition, simple existing limits on the isocurvature contribution to CMB anisotropies would definitively rule out a contribution of more than 5% to r≈0.2. …”

Constraints on large scale inhomogeneities from WMAP-5 and SDSS: confrontation with recent observations
Published 2008“…With the smaller global Hubble parameter, the WMAP-5 data on cosmic microwave background anisotropies can be fitted without requiring dark energy if there is some excess power in the spectrum of primordial perturbations on 100 Mpc scales. …”

Is the evidence for dark energy secure?
Published 2007“…The dimming of distant Type Ia supernovae suggests that the expansion rate is accelerating, as if driven by vacuum energy, and this has been indirectly substantiated through studies of angular anisotropies in the cosmic microwave background (CMB) and of spatial correlations in the large-scale structure (LSS) of galaxies. …”

Evidence for polarons and itinerant carriers in superconductivity from time-resolved optical measurements on YBa2Cu3O7-Delta
Published 1997“…Spectrally, the superconducting condensate is also found to be coupled to two distinct components in frequency (for both carriers): one below 0.1 eV and one in the range 1.5-2 eV, but with different anisotropies. A natural explanation of these datas is that the two types of carriers correspond to the two phases suggested by the structural data and as such present the first direct evidence of two-component superconductivity. …”

Giant Dzyaloshinskii-Moriya interaction, strong XXZ-type biquadratic coupling, and bimeronic excitations in the two-dimensional CrMnI6 magnet
Published 2023-07-01“…Abstract Two-dimensional magnets have been discovered recently as a new class of quantum matter exhibiting a broad wealth of exotic phenomena, including notably various topological excitations rooted in emergent exchange couplings between the localized magnetic moments. By analyzing the anisotropies in the single-ion magnetization and two-body exchange couplings obtained from first-principles calculations, we reveal coexistence of both giant Dzyaloshinskii–Moriya interaction and strong anisotropic XXZ-type biquadratic coupling in a recently predicted monolayer CrMnI6 magnet. …”

Furthermore, 91% of the studied QDs exhibit a polarization axis along the crystal [1–100] axis, with the other 9% polarized orthogonal to this direction. …”

Frustration-driven magnetic fluctuations as the origin of the low-temperature skyrmion phase in Co7Zn7Mn6
Published 2021-04-01“…The influences of other leading skyrmion stability mechanisms, such as those derived from thermal fluctuations and low T cubic anisotropies, are shown to be weak in this system. We therefore advance the existence of a fundamental mechanism for stabilizing topological skyrmions in Co7Zn7Mn6 chiral magnet that draws upon magnetic frustration as the key ingredient.…”
