An Accidental Relationship Between a Relative Quantum

Therefore, the search of observables related to entanglement, including entanglement witnesses, is an important goal. In this paper we show a result in that direction. For ...

Solution to Exercise 2.1-2: Density of States for Lower Dimensions
... The consequences can be pretty dramatic. Consider, e.g. the concentration of electrons you can get in the three case for E ≈ 0 eV, i.e close to the band edge. The question, of course, is: Are there 1-dim. and 2-dim. semiconductors? The answer is: yes - as soon as the other dimensions are small enoug ...
