In quantum mechanics, the energy of a confined system can take on only certain quantized values. An atom (the nucleus and the electrons) is a quantum system that follows this rule; its energy levels are discrete due to the nature of quantum mechanics. For any given atom, there are only s...
With a self-consistent field average atoms scheme, it is shown that the energy-level broadening has a significant effect on the isothermal equation of state (EOS) of Al and Au in the hot dense matter regime. The jumps in the equation of state (EOS) induced by pressure ionization of the ...
Changes in the mean ionization energy of atoms in compressed matter are estimated through cage models of atomic confinement whereby pressure is obtained in... SA Cruz,C. Diaz-Garcia,AP Pathak,... - 《Nuclear Instruments & Methods in Physics Research》 被引量: 12发表: 2005年 Development of ...
(General Physics) an equation that equates the product of the pressure and the volume of one mole of a gas to the product of its thermodynamic temperature and thegas constant.The equation is exact for an ideal gas and is a good approximation for real gases at low pressures. Also called:...
In the present study, considering the relationship with charge of the electronic energy for atoms, Sanderson's electronegativity equalization principle and Density Functional Theory (DFT), we have obtained a new equation by which group electronegativity can be calculated from ionization energies (I) ...
We revisit the theoretical priors used for inferring Dark Energy (DE) parameters. Any DE model must have some form of a tracker mechanism such that it behaved as matter or radiation in the past. Otherwise, the model is fine-tuned. We construct a model-independent parametrization that takes th...
By means of the two-particle Green's function, a study is made of the level shifts of one-electron atoms in a plasma and of the equation of state of a Debye plasma. It is shown that low-energy states experience a shift proportional to the root of the density and to the ratio kT/ ...

The liquid-vapor phase change, ionization process, and chemical equilibrium among dissociation products of water are all considered. Theoretical results and experimental data are compared and several interesting aspects of the thermodynamics of water are discussed. 关键词: inorganic, organic, physical and...
systems of linear algebraic equations. MATLAB has many functions that assist in this process. Once the system of equations has been written in matrix form, what we want is to solve the equation Ax = b for the unknowns x. To do this, we need to isolate x on one side of the equation...
