according to the Pauli exclusion principle, two or more electrons cannot occupy the same orbital. Therefore, as the state of matter changes from a single atom to a molecule to a crystal, their electron orbitals come to form a continuous band structure of energy levels ...
electrons. Valence electrons are involved in bonding. Atoms will gain or lose electrons to make their outer shell full, the atom becomes charged and is called an ion. Cation = atom that loses an electron and becomes positively charged Anion = atom that gains an electron and becomes negatively...
strongly correlated electron systemDyson equationGreen’s functiondegenerate Hubbard modelWe investigate the minimal model that takes orbital degrees of freedom into account: the degenerate two-orbital Hubbard model. Our consideration includes the intraatomic Coulomb interaction of two electrons with opposite...
Electron configurations The electron configuration of an element refers to the arrangement of electrons in its shells and subshells. Elements in the same column have the same electron configuration in their outer shell. For example, all the elements in column 18 (the noble gases) have a full ou...

The role of the harmonic oscillator frequency in the implementation of the Gaussian model potential is discussed, and the effect of an external magnetic field is identified to be similar to choosing a more localized electron wave function in microscopic calculations. The full matrix form of the ...
Electron Configuration Electron configuration can be defined as the distribution of electrons across the orbitals of an atom. Each neutral atom has a fixed number of electrons which equals the number of protons present and is called the atomic number. Along with the protons and electrons, the atom...
Each atom has a particular number and organization of the electrons in its electron cloud. Often scientists need or would like to know how the different electron shells and sub-shells (orbitals) are filled, especially with respect to the principle quantum numbers describing the electrons. One tool...
