We investigate the behavior of polarized dipolar fermions in a two-dimensional harmonic trap in the framework of the density functional theory (DFT) formalism using the local density approximation. We treat only a few particles interacting moderately. Important results were deduced concerning key characteristics of the system such as total energy and particle density. Our results indicate that, at variance with Coulombic systems, the exchangecorrelation component was found to provide a large contribution to the total energy for a large range of interaction strengths and particle numbers. In addition, the density profiles of the dipoles are shown to display important features around the origin that is not possible to capture by earlier, simpler treatments of such systems.

Density functional theory (DFT) study of BaScO3H0.5 compound and its hydrogen storage properties Gencer, Ayşenur; Surucu, Gokhan (Canadian Science Publishing, 2019-11-01) BaScO3 and its hydride BaScO3H0.5 have been investigated using density functional theory (DFT) with the generalized gradient approximation (GGA). BaScO3 perovskite can crystallize in five possible crystal structures: orthorhombic (Pnma), tetragonal (P4mm), rhombohedral (R-3c), hexagonal (P63/mmc), and cubic (Pm-3m). These five possible phases have been optimized to obtain the most stable phase of BaScO3. The orthorhombic phase, being the most stable and having the lowest volume among the studied phases, has...
Conserved charges in extended theories of gravity Adami, Hamed; Setare, Mohammad Reza; Sisman, Tahsin Cagri; Tekin, Bayram (Elsevier BV, 2019-11-20) We give a detailed review of construction of conserved quantities in extended theories of gravity for asymptotically maximally symmetric spacetimes and carry out explicit computations for various solutions. Our construction is based on the Killing charge method, and a proper discussion of the conserved charges of extended gravity theories with this method requires studying the corresponding charges in Einstein's theory with or without a cosmological constant. Hence we study the ADM charges (in the asymptoti...
Dirichlet extremum problem associated with the asymmetric grain-boundary thermal grooving under the Dirac delta-type anisotropic surface stiffness in bicrystal thin solid films Ogurtani, Tarik Omer (AIP Publishing, 2007-09-15) A generalized Rayleigh-Ritz (RR) method combined with the Galerkin (RRG) functional space approximation is elaborated by using the extended and modified Laguerre functions manifold for the weak solution of the asymmetric grain-boundary thermal grooving problem with the Dirichlet boundary. This new hybrid RRG approach, which resembles the front-tracking method, reveals the fine features of the grain boundary groove-root topography (rough or faceted regions) more accurately than the previous approach under th...
Discrete symmetries and nonlocal reductions GÜRSES, METİN; Pekcan, Asli; Zheltukhın, Kostyantyn (Elsevier BV, 2020-01-31) We show that nonlocal reductions of systems of integrable nonlinear partial differential equations are the special discrete symmetry transformations.
Approximate solution to the time-dependent Kratzer plus screened Coulomb potential in the Feinberg-Horodecki equation Farout, Mahmoud; Sever, Ramazan; Ikhdair, Sameer M. (IOP Publishing, 2020-06-01) We obtain the quantized momentum eigenvalues P-n together with space-like coherent eigenstates for the space-like counterpart of the Schrodinger equation, the Feinberg-Horodecki equation, with a combined Kratzer potential plus screened coulomb potential which is constructed by temporal counterpart of the spatial form of these potentials. The present work is illustrated with two special cases of the general form: the time-dependent modified Kratzer potential and the time-dependent screened Coulomb potential.
