The major characteristic of the single-band Hubbard model (HM) is to redistribute electrons at a uniform lattice separation distance within the molecular lattice. Hence, it is only linearly dependent on lattice separations distance. Thus the single-band Hubbard model does not con...

In this paper, we investigate the effects of electron inertia on the gravitational instability of gaseous plasma under the influence of FLR (Finite Larmor Radius) corrections and suspended particles. A general dispersion relation has been derived through relevant linearized pertu...

F-theory, as Theory of everything is compactified on Calabi-Yau threefolds or fourfolds. Using Batyrev’s toric approximation and mirror symmetry of Calabi-Yau manifolds it is possible to present Calabi-Yau in the form of dual integer polyhedra. With the help of Gelfand, Zelevinsk...

The thermal conductivity of carbon nanotubes (CNTs) depends on their length and the diameter. At room temperature, the thermal conductivity of CNTs increases as its length increases as well as its diameter decreases. Aligned long single-walled carbon nanotubes (AL-SWCNTs) are exp...

We note the similarity between BEC (Bose-Einstein Condensates) formed of atoms between which we have long-range attraction (and shorter-range repulsions) and the field theoretic ”Q balls”. This allows us in particular to address the stability of various putative particle physics...

The author has developed a dynamic model (DM) to simulate the surface temperature change (ΔT) caused by the eruption of Mount Pinatubo. The main objectives have been 1) to test the climate sensitivity parameter (λ) values of 0.27 K/(Wm-2) and 0.5 K/(Wm-2), 2) to test the time con...

We present a two-dimensional analysis of the two-electron problem which comes from the classical conservation theorems and from which we obtain a version of the Dirac equation for the helium atom. Approximate solutions for this equation are discussed in two different methods, alt...

In this work the quantum gravitational equations are derived by using the quantum hydrodynamic approach that allows to define the energy-impulse tensor density of the gravitational equation. The outputs of the work show that the quantum uncertainty principle opposes itself to the...

In this paper we describe the peculiarities of the thermodynamics of the absorption heat transformers (AHTs) pointing to the possibility of examining the AHT models from the standpoint not only of the equilibrium thermodynamics, as it usually is, but also of the non-equilibrium o...
