Orbital order in classical models of transition
... which defines the 120 -model on the level of a quantum spin system. In the t2g compounds (e.g., LaTiO3 ) the general form of Eqs. (1-2) is preserved but the appropriate choice of the π̂rα ’s is now π̂rα = 12 σrα for α = x, y, z, see [13]. This is called the orbital compass model. It is worth noting ...

Quantum information processing by nuclear magnetic resonance
... Demonstrations of QIP by liquid-state NMR utilize an ensemble of identical molecules, each containing one or more atomic nuclei with an intrinsic angular momentum of ប/2 共spin 1/2兲. Such a nucleus, itself called a ‘‘spin,’’constitutes an ideal qubit, because the component of its angular momenta meas ...

... Electron Spin Electrons have an intrinsic spin which is also spatially quantized. Spinning charges behave like dipole magnets. The Stern-Gerlach experiment uses a magnetic field to show that only two projections of the electron spin are allowed. By analogy with the l and ml quantum numbers, we see t ...

Optical and Magnetic Properties of Copper(II) compounds.
... restrictions defining the pairs of energy levels between which such transitions can occur are called electron dipole selection rules.29 These rules, which can be explained in terms of symmetry of the wave-functions, are true only in the first approximation. The forbidden transitions are often observed ...
