After the discovery of magnetism in monolayer CrI3, magnetic properties different 2D materials from chromium-trihalide family are intuitively assumed to be similar, yielding anisotropy spin-orbit coupling on halide ligands. Here we reveal significant differences between CrI3 and CrBr3 monolayers their anisotropy, resulting Curie temperature, hysteresis external field, evolution with strain, all...

Spatial variations in the rigidity of continental plates (expressed in terms of an effective elastic thickness, Te) can have a profound influence on the style of deformation of ocean–continent convergent margins. Depending on the spatial distribution of Te, strains related to plate boundary forces can become concentrated where Te is small. We calculate Te and Te anisotropy in western Canada by ...

The Tolman-Bondi solution of the Einstein equations is used in order to model the time evolution of the void observed in Boötes. The present density contrast of the central region (∼ −0.75) and its radius (∼ 30h−1 Mpc) are fixed, while the density parameter of the Universe, the amplitude of the density contrast inside the void wall, the width of this wall and the distance from the void centre t...

These lecture notes discuss several topics in the physics of cosmic structure formation starting from the evolution of small-amplitude fluctuations in the radiation-dominated era. The topics include relativistic cosmological perturbation theory with the scalar-vector-tensor decomposition, the evolution of adiabatic and isocurvature initial fluctuations, microwave background anisotropy, spatial ...

Context. In nearby clusters early-type galaxies follow isotropic orbits. The orbits of late-type galaxies are instead characterized by slightly radial anisotropy. Little is known about the orbits of the different populations of cluster galaxies at redshift z > 0.3. Aims. We investigate the redshift evolution of the orbits of cluster galaxies. Methods. We use two samples of galaxy clusters spann...

The analytic expression of the time evolution of the Reynolds stress anisotropy tensor in all planar homogeneous ows is obtained by exact integration of the modeled di erential Reynolds stress equations. The procedure is based on results of tensor representation theory, is applicable for general pressure-strain correlation tensors, and can account for any additional turbulence anisotropy e ects...
