... 4. Neutrino oscillations In the standard QM treatment [15], the Pontecorvo states (35)–(36) are usually assumed to be produced in a charged current weak interaction process, together with the respective charged (anti-) leptons. However, as we have shown above, such states are not eigenstates of the ...

Each qubit is controlled by applying a voltage to an A gate electrode that displaces slightly the wavefunction of the bound electron, and thus modifies the hyperfine interaction. The two qubit operations are performed ...

A new approach for the two-electron cumulant in natural orbital
... conditions that have to be imposed on variations of ⌫ are well known [12]. Finally, the natural orbital functional (NOF) incorporates fractional occupation numbers in a natural way, which provides a correct description of both dynamical and nondynamical correlation. An NOF requires an expression of ...

It is, though, a particular way of handling available information and uncertainty, and certainly not the only possible approach. There is an alternative solution to this problem that, involving different assum ...

The first general treatment for many-electron atoms was proposed by Hartree22, who suggested that electrons in atoms would move independently of each other, the motion of each one of the electrons being influenced by the electrostatic potential of the nucleus and an average field due to all the othe ...

Both the 0.7 anomaly and the Kondo signatures show a periodic modulation as a function of QPC length, which can be explained by a varying number of spontaneously localized states. We show using spin-density-functional theory calculations that the number of ...
