Ab initio calculations in a uniform magnetic field using periodic supercells.
We present a formulation of ab initio electronic structure calculations in a finite magnetic field, which retains the simplicity and efficiency of techniques widely used in first principles molecular dynamics simulations, based on plane-wave basis sets and Fourier transforms. In addition we discuss results obtained with this method for the energy spectrum of interacting electrons in quantum wel...
متن کاملElectronic structure calculations in a uniform magnetic field using periodic supercells
We have recently presented a method that allows one to use periodic supercells in ab initio electronic structure calculations in the presence of a finite magnetic field [Phys. Rev. Lett. 92 (2004) 186402]. This method retains the simplicity and efficiency of plane-wave basis sets and Fourier transforms. The original formulation was developed for cubic cell and for the k = (0,0,0) point of the s...
متن کاملNanofluid Flow in a Semi-porous Channel in the Presence of Uniform Magnetic Field
In this paper, the problem of laminar nanofluid flow in a semi-porous channel is investigated analytically using Homotopy Perturbation Method (HPM). This problem is in the presence of transverse magnetic field. Here, it has been attempted to show the capabilities and wide-range applications of the Homotopy Perturbation Method in comparison with the numerical method in solving such problems. The...
متن کاملRapid mixing of Newtonian and non-Newtonian fluids in a three-dimensional micro-mixer using non-uniform magnetic field
The mixing of Newtonian and non-Newtonian fluids in a magnetic micro-mixer was studied numerically using ferrofluid. The mixing process was performed in a three-dimensional steady-state micro-mixer. A magnetic source was mounted at the entrance of the micro-channel to oscillate the magnetic particles. The effects of electric current, inlet velocity, size of magnetic particles, and non-Newtonia...
متن کاملEffect of non-uniform Magnetic Field on Non-Newtonian Fluid Separation in a Diffuser
The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...
