... −1, 0, +1) so is there a preference? Also, Hund only predicts ground states… what about higher energy excited states? Also, are the electrons paired or unpaired? Again, Hund says they should have parallel spins, but to have two electrons in different p orbitals with one being spin “up” and the other ...

... There are letters associated with values of orbital angular momentum. The first few are: For example, state with n=1 l=0 is referred to as 1s, n=2 l=0 is referred to as 2s, n=2 l=1 is referred to as 2p, and so on. While the energies are the same for the four n=2 states, the wave functions are not: ...

... The simplest physical realization of SU(4) symmetry group is a two-well potential with one electron inside. Electron is characterized by spin with two projections (up and down) and its position in the wells (left and right). Both quantum numbers are realized by means of Pauli matrices σ and τ (spin ...

Nitrogen-vacancy center
The nitrogen-vacancy center (N-V center) is one of numerous point defects in diamond. Its most explored and useful property is photoluminescence, which can be easily detected from an individual N-V center, especially those in the negative charge state (N-V−). Electron spins at N-V centers, localized at atomic scales, can be manipulated at room temperature by applying a magnetic field, electric field, microwave radiation or light, or a combination, resulting in sharp resonances in the intensity and wavelength of the photoluminescence. These resonances can be explained in terms of electron spin related phenomena such as quantum entanglement, spin-orbit interaction and Rabi oscillations, and analysed using advanced quantum optics theory. An individual N-V center can be viewed as a basic unit of a quantum computer, and it has potential applications in novel, more efficient fields of electronics and computational science including quantum cryptography and spintronics.
