Physics 4307
Introduction to Quantum Mechanics
Homework Assignment 4
Due Date: 2:00 p.m. on Tuesday, October 20, 2015
Important! Make a copy of this homework to study for your midterm
before you turn it in. Work out exercise 7.1 as well as problem 7.5. Also,
- Consider the 1-D delta function well: V(x) = -α δ(x) where
α is a positive constant and V(x) = 0 for x ≠ 0. Find all of the
bound state energies (assuming E < 0 for bound states) as well as any
wave functions for this potential. If any exist, plot the wave functions.
- For the infinite 1-D square well of width L, find the minimum possible
energy when 6 non-interacting fermions that obey the Pauli exclusion
principle are in this well. What is the minimum energy for 6
non-interacting bosons?
Please write these
up in a "complete" fashion by using some well chosen words, diagrams, and
graphics to space out the math. Good Luck!!
