Abstract In this work, corrections for the Weyl law and conjecture in d dimensions are obtained effects related to polarization area term analyzed. The derived formalism is applied on quasithermodynamics of electromagnetic field a finite -dimensional box within semi-classical treatment. context, Stefan–Boltzmann obtained. Special attention given two-dimensional scenario, since it can be used ch...
in this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. we have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. the spin-polarization parameter corresponding to the equilibrium state of ...
The most effective way to express the mathematical and physical research results is by using formulas. Our article contains formulas that were biggest contributors development of technical, physical, sciences. can be applied in different areas. In this article, we will show how calculate an orbit a miniature satellite based on Law Gravity. For calculations online recording results, are MATLAB s...
the density and polarization profiles of the dipolar hard ellipsoids confined between hard walls are studied using the density functional theory (dft). the hyper-netted chain (hnc) approximation is used to write excess grand potential of the system with respect to the bulk value. the number density is expanded up to zero and first order in polarization to find the results. for the zero order in...
The measurement of the polarization of cosmic microwave background (CMB) provides considerable useful information about different physical phenomena at the last scattering surface. The polarization of CMB is due to Compton scattering. In this work, we consider the parity violation of Compton scattering. Then we insert the new amplitude into the quantum Boltzmann equation and show that the forwa...
In this paper we, obtain the weight of radial basis finite difference formula for some differential operators. These weights are used to obtain the local truncation error in powers of the inter-node distance and the shape parameter of radial basis functions. We show that for each difference formula, there is a value of the shape parameter for which RBF-FD formulas are more accurate than the cor...
We address the question of different representations Bloch states for lattices with a basis, focus on topological systems. The differ in relative phase Wannier functions corresponding to diffferent basis members. show that can be chosen such way sites both become eigenstates position operator particular band. A key step showing this is extension Brillouin zone. When distance between within unit...

in this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled inas/gaas quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. the microcavity wafer sample is grown by molecular beam epitaxy (mbe) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...
