... If we turn on the interband mixing of the opposite chirality, localized loops may become less localized. In order to see this, let us consider an extreme case with no tunneling at saddle points, but with such a strong interband mixing that an electron will move from a loop, say, around a peak, to a ...

The p orbital paradox
... The formulation of the paradox begins by assuming that a single electron finds in some point of a lobe at instant t and in another point of the other lobe at some posterior instant t'. Then the paradox arises when trying to unite both points with a trajectory without passing by the nodal plane. It ...
