Recently introduced exact solution of the Einstein gravity coupled minimally to an anisotropic fluid representing dark matter can well represent supermassive black holes in galactic nuclei with realistic distribution around hole, given by Hernquist-like density distribution. For these fluid-hairy hole spacetimes, properties gravitational radiation, quasinormal ringing, and optical phenomena wer...

Fluid flows through anisotropic media are found in a wide variety of geophysical and biological systems. The macroscale behavior of these systems depends on the microstructure, which in turn may depend on local and global physical processes. Classically, geometric restrictions are needed to model these systems on the largest length scale, and we are interested in developing effective models whi...

A one-dimensional model of a small plasma ion source 10 cm long is studied. A hybrid simulation where ions are treated as particles and electrons as a fluid obeying the Boltzmann relation is used to investigate ion heating in the plasma presheath. At low pressure below a few mTorr , the ion velocity distribution is Maxwellian in the bulk and becomes a drifting Maxwellian distribution while tran...

Defects in the band gap of CuIn12xGaxSe2 have been characterized using transient photocapacitance spectroscopy. The measured spectra clearly show response from a band of defects centered around 0.8 eV from the valence band edge as well as an exponential distribution of band tail states. Despite Ga contents ranging from Ga/(In1Ga)50.0 to 0.8, the defect bandwidth and its position relative to the...

Understanding the complexity of anisotropic turbulent processes in engineering and environmental fluid flows is a formidable challenge with practical significance because energy often flows intermittently from the smaller scales to impact the largest scales in these flows. Conceptual dynamical models for anisotropic turbulence are introduced and developed here which, despite their simplicity, c...

Abstract This work is devoted to the construction of a new static and spherical solution for an anisotropic fluid distribution. The based in framework gravitational decoupling through particular case extended minimal geometric deformation called 2-steps GD. In this sense, differential equations arising from are closed using vanishing complexity factor. Heintzmann IIa used as seed solution. fulf...

We have studied a simple model colloidal fluid to assess the role of anisotropic interactions in crystallization process when the interaction potential is short ranged compared with the size of the molecule, which is the case for the effective interaction between protein molecules in aqueous solutions. Using Monte Carlo simulations we have calculated the phase diagrams of soft dumbbell systems ...
