View larger. Download instructor resources. Additional order info. This text first teaches students how to do quantum mechanics, and then provides them with a more insightful discussion of what it means. Fundamental principles are covered, quantum theory presented, and special techniques developed for attacking realistic problems.

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. Solve Eq. Now from Eqs. In Eq.

Introduction to Quantum Mechanics 2nd Edition David J. Griffiths

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: Odd solutions: Add 1 and 2: So for every positive n there are two solutions: Any other solution with the same energy is a linear combination of these.

Exponential decay outside, sinusoidal inside the wells, hyperbolic cosine in barrier. First excited state is odd — hyperbolic sine in barrier. Hence the graph next page. This is consistent with the graphs above.

But from Problem 2. Check normalization: The wave packet is dragged along at speed v with the delta-function. The total energy is the energy it would have in a stationary delta-function E , plus kinetic energy due to the motion 1 2 mv2. Note that the delta-well S matrix in a has this property.

Subtract 2 from 1: Evidently K lies between 0. The results see below are 3. QED The set of all normalized functions is certainly not a vector space: Equation A. As for Eq.

Problem 3. Adding the last two equations: QED Problem 3. Integrating by parts twice: As in Example 3. The periodicity condition Eq. So both of them are eigenfunctions, with the same eigenvalue 1. They are clearly orthogonal, since sinh x is odd while cosh x is even.
