... We can then summarize as follows: (i) For macroscopic particles, ∆x and ∆px will be negligible compared to h x i and h px i. At the same time, the variation of F over the extension of the wave packet will be insignificant, so that h F (x) i = F (h x i), to a very good approximation. In this case, th ...

A Critique of “A Critique of Two Metals”
... Finally, we object to the statement that Zhang articulates “an alternate view in a particularly simple and elegant way . . . . . that everyone can understand”. We, for one, find that the presentation, while extremely smooth, is not in any way understandable, since it is expressed in terms which we c ...

V. Time Dependence A. Energy Eigenstates Are Stationary States
... In order to apply these equations in practice, one can follow a simple ansatz. First, pick a basis χ n , preferably one in which the matrix elements of Hˆ can be easily computed. As shown above, the extreme example of this is the energy eigenbasis, where H is just a diagonal matrix. However, in prac ...
