the squared modulus of the wave function is the probability density
... Imagine that the nucleus (proton) is surrounded by a thin spherical “shell” of radius r and thickness dr . We want to determine the probability of finding the electron within the volume of this shell. ...

... It is clear from Eq. (1.23) that if the position of the particle is known exactly, then the knowledge of its momentum is completely lost. In general the product of the two uncertainties has to be greater than ~/2. It is important to appreciate that Heisenberg’s inequalities reflect a physical limita ...

1 The density operator
... J = 0, with λ0 = 1. Then ρ = 0 0 , so ρ is a projection onto the state 0 and thus represents a pure state. Could we then be sure that there is not another representation of the form (4) in which ρ is a mixed state? Also yes, but we have to think a little more carefully. Suppose that there is an ...

6.2 Growth and structure of semiconductor quantum wells
... functions with differing quantum numbers are not necessarily orthogonal to each other because of the differing decay constant in the barrier regions. This means that there are small departures from the selection rule of a infinite quantum well. However these non-zero transitions are usually weak, an ...
