We study the emergent role of many-body effects on a two-dimensional electron gas (2DEG) within the Thomas-Fermi-Dirac-Poisson approximation, including both the exchange and correlation interactions in the presence of a strong perpendicular magnetic field. It is shown that the indirect interactions widen the odd-integer incompressible strips spatially, whereas the even-integer filling factors almost remain unaffected.

The Wigner molecule in a 2D quantum dot Akman, N; Tomak, Mehmet (1999-10-01) The charge density and pair correlation function of three interacting electrons confined within a two-dimensional disc-like hard-wall quantum dot are calculated by full numerical diagonalization of the Hamiltonian. The formation of a Wigner molecule in the form of equilateral triangular configuration for electrons is observed as the size of the dot is increased.
The effect of peripheral circuits on the total pi-electron energies of cyclacenes Türker, Burhan Lemi (2000-01-01) Within the framework of the Huckel molecular orbital theory, certain linear models are developed to express the contribution of peripheral circuits of cyclacenes into their total pi -electron energies, which explain why cyclacenes exhibit the cryptoannulenic behavior as their peripheral circuits which are annulenic in character.
The spin effects on electronic, optical and mechanical properties of new ferromagnetic chalcopyrite: YMnS2 Yıldız, Buğra; Erkisi, Aytac; Sürücü, Gökhan (2022-05-15) In this study, magnetic and electronic nature, optical behavior, and elasticity properties of YMnS2 compound have been investigated by using density functional theory (DFT). The compound belongs to the chalcopyrite family having tetragonal crystal structure with 122 (I-42d) space group. Firstly, the optimization process has been done for ferromagnetic, antiferromagnetic, and paramagnetic orders to find most stable magnetic order and the formation energies have been determined. Negative formation energies pr...
The use of curl-conforming basis functions for the magnetic-field integral equation Ergül, Özgür Salih (2006-07-01) Divergence-conforming Rao-Wilton-Glisson (RWG) functions are commonly used in integral-equation formulations to model the surface current distributions on planar triangulations. In this paper, a novel implementation of the magnetic-field integral equation (MFIE) employing the curl-conforming (n) over tilde x RWG basis and testing functions is introduced for improved current modelling. Implementation details are outlined in the contexts of the method of moments, the fast multipole method, and the multilevel ...
The effect of substitutional impurities on the evolution of FeAl diffusion layer Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (Elsevier BV, 1998-2-13) The formation and growth characteristics of Fe based aluminide diffusion layers at the Fe-Al interface have been analysed in terms of interfacial interaction potentials based on the statistico-thermodynamical theory of multicomponent alloys combined with electronic theory in the pseudopotential approximation. The pairwise interatomic interaction potentials and partial ordering energies have been calculated to predict the effect of various alloying additions on the activity coefficient of Al atoms in α-Fe0.9...
