Small water droplets dispersed in a nematic liquid crystal exhibit a novel class of colloidal interactions, arising from the orientational elastic energy of the anisotropic host fluid. These interactions include a short-range repulsion and a long-range dipolar attraction, and they lead to the formation of anisotropic chainlike structures by the colloidal particles. The repulsive interaction can...

Abstract In this work, we construct a new stellar model in the regime of anisotropic fluid pressure using concept vanishing complexity for spherically symmetric distributions (Herrera Phys Rev D 97:044010, 2018) and convenient ansatz order to close Einstein’s field equations. The resulting fulfills fundamental physical acceptability conditions specific set compactness factor. stability its resp...

We construct conformastat spherically symmetric spacetimes representing anisotropic fluid matter distributions from given solutions of the Poisson's equation Newtonian gravity and its corresponding circular speed profile. As simple examples, we present three families which apply in constructing new models relativistic thick spherical shells, galaxy composite by a central bulge, disk dark halo, ...

This paper is devoted to the numerical approximation of a degenerate anisotropic elliptic problem. The numerical method is designed for arbitrary space-dependent anisotropy directions and does not require any specially adapted coordinate system. It is also designed to be equally accurate in the strongly and the mildly anisotropic cases. The method is applied to the Euler-Lorentz system, in the ...

Abstract Anisotropic pressure dark energy stars are recently proposed as an alternative model to gravastar. However, the nature’s classification of the fluid was based on the interval of the parameter ω, defined by the state equation that comes directly from the isotropic pressure Friedmann cosmological models. This procedure is not correct. In this work we propose a generalization of the limit...

A complete theoretical presentation of the Continuum-mechanical, Anisotropic Flow model, based on an anisotropic Flow Enhancement factor (CAFFE model) is given. The CAFFE model is an application of the theory of mixtures with continuous diversity for the case of large polar ice masses in which induced anisotropy occurs. The anisotropic response of the polycrystalline ice is described by a gener...

We have examined the spatial distribution of substructure in clusters of galaxies using Einstein X-ray observations. Subclusters are found to have a markedly anisotropic distribution which reeects the surrounding matter distribution on supercluster scales. Our results suggest a picture in which cluster formation proceeds by mergers of sub-clusters along large-scale laments. The implications of ...
