Quantifying Entanglement
... effort has been placed on precisely defining just how much entanglement there is in a system. The simple case of pure states of two-part systems is rather well understood, since the von Neumann entropy is the only “reasonable” measure in this context. Things get more complicated, however, in the mix ...

Modelling the electron and hole states in semiconductor
... field and mechanical strain are modelled in the k · p theory. When applied to nanostructures, the multiband k · p theory could give rise to spurious solutions, which are an artifact due to an incomplete description of the electronic structure by the k · p theory. In practice, spurious solutions are ...

If we did that we would necessarily find just one of the states, q i , to which we would then assign an entropy of zero. The density matrix (3.2.5.2) does, however, a ...
