QED Problem 1. This is just barely consistent with the uncertainty principle. In view of Eq. We want the magnitude of dx here. To get x and x2 from Problem 1. So for a given value of y, the probability of crossing using Problem 1. But Eq.

Odd integrand. QED Problem 2. By the same token, if it starts out heading negative, it just runs more and more negative. Problem 2. Independent of n.

Therefore, from Eq. These results hold for any stationary state of the harmonic oscillator. From Eqs. Right at the uncertainty limit. Classically allowed region extends out to: Continuity at a: Plot both sides and look for intersections: Now look for odd solutions: Only even: Impose boundary conditions: To solve for C and D, add 2 and 4: Equate the two expressions for 2C: Equate the two expressions for 2D: Solve these for F and B, in terms of A.

Wide, deep well: Same as Eq. Shallow, narrow well: So z0 is small, and the intersection in Fig. Actions Shares. Embeds 0 No embeds.

Wide, deep well: Same as Eq. Shallow, narrow well: So z0 is small, and the intersection in Fig. Solve Eq. Now from Eqs. In Eq. Multiply Eq. Put these into Eq. Likewise, from Eq. Now subtract 2 from 1: You can also get this from Eq. Use 4 to eliminate D in 2. Alternatively, from Problem 2. In either case Eq. So apart from normalization we recover the results above.

The graphs are the same as Figure 2. So Eq.

Normalize using Eq. Most probable: QED b The classical revival time is the time it takes the particle to go down and back: Referring to the solution to Problem 2. So far, this is correct for any bound state.

Expand the term in square brackets: Even solutions:
