... energy eigenfunction. This approach is a feature of many quantum mechanical methods. If the perturbation is small, the results are quantitatively very accurate. This is the case in NMR when the scalar spin-spin coupling constants are small compared with the difference in chemical shifts. First order ...

... Consider a string of length L and mass-per-length µ which is, as usual, clamped at both ends. Assume the tension is T. Express the Hamiltonian density in terms of the Fourier coefficients, thereby converting the problem to one of particle dynamics. (Hint: Expand the displacement in terms of the spat ...

... Problem 3.1 Use WKB to estimate the g.s. (n = 0) energy for the gravitational (linear) potential, V(y) = mgy. Don’t forget there is a “rigid wall” at y = 0. Also compute the energy for excited states (n > 0). Problem 3.2. Shankar 16.2.5; this is actually an application of results from problem 3.2. P ...
