Abstract: A novel H atom model is devised using electron orbits located in planes not passing through the proton and are transversal or perpendicular to an axis originating at the proton center, and hence they are orthogonal to the longitudinal planes used in Bohr H atom model. The physical foundations for the proposed model are desc [...] Read more.

Abstract: According to Aristole’s Categories, there are three kinds of concept, i.e. substance, quality and quantity in physics. With the question “What is heat?”we mean : is heat a substance, a quality or a quantity? Historically, heat was referred to a substance caloric. Now, it is prevailed that heat is a quantity Q, also called “ [...] Read more.

Abstract: The effect of electron irradiation with the energy of 10 MeV on the electrical properties of n-Ge single crystals is investigated. Based on measurements of the Hall effect, the temperature dependences of the resistivity, concentration and mobility of current carriers for the range of 180–280 K have been obtained. It was sho [...] Read more.

Abstract: A quantum harmonic oscillator with a frequency modulation is an extensively studied model, and has relevance to important physical processes. In this paper we consider response of the frequency modulation in terms of the time dependence of quasi energies and the deviation from the quantum virial theorem. Four modulation typ [...] Read more.

Abstract: Light displays particle and wave properties within the bounds of the inequality, K^2+V^2≤1, where K represents particle information and V represents corresponding wave information. Using two laser beams that cross and then diverge from each other we explore the inequality. Results, based on semiclassical analysis, are in co [...] Read more.

Abstract: When linearly polarized light impinging on a lens, it will reflect and refract along the lines curves resulting from the interception of a plane (plane of polarization) with a sphere (lens surface) maintaining the orientation of refraction and reflection within the plane of polarization. This effect is significant [...] Read more.

Abstract: In this paper, it is shown that the Magnus effect cannot be a primary mechanism for the dispersion of shotgun pellets. The one-dimensional motion of objects through air, applied to shotgun pellets traveling a short distance, reveals that throughout the flight, the Reynold’s number is approximately constant. The distribution [...] Read more.

Abstract: The research of plastic deformation of metals attaches great importance to stacking fault energy (SFE). In this paper, we derive the expressions of four types (I1, I2, E and T2) of basal plane SFEs of hcp-Ti within the framework of the Ising model. Based on this model, alloying effects on the stacking fault energy (SFE) of [...] Read more.
