In quantum mechanics, the expectation value of the energy of a system in the state (x) in one dimension is given by (E)-i (1) where -h2 a V(x) 2m Or2 Find the condition on (r) that makes (E) stationary, subject to the constraint that (a)(r)dz =1
5. Essay on Quantum Mechanics (40 pts) In this problem, you will need to write down your short essay on quantum mechanics. You’re NOT allowed to discuss this problem with your classmates or instructor: therefore, your answer here should be unique, and be NOT even similar to that of others. Just think by yourself and freely state what you learned and how you feel about quantum mechanics now. You may want to include the following specific topics in your essay....
State Bohr's postulates and use them to determine the expression for i) radius of Bohr orbit ii) total energy of the electron in a hydrogen atom in the nth state
A hydrogen atom is in the n = 6 state. Determine, according to quantum mechanics, (a) the total energy (in eV) of the atom, (b) the magnitude of the maximum angular momentum the electron can have in this state, and (c) the maximum value that the z component Lz of the angular momentum can have.
Quantum Mechanics : (Selection rule) Discuss the physical basis for the selection rule that a transition from one state of angular momentum zero to another state of angular momentum zero by emitting a photon, is forbidden.

From A Modern Approach to Quantum Mechanics by Townsend 12.6. Consider the one-dimensional system of a particle of mass m in a uniform gravitational field above an impenetrable plane. Take the potential energy to be infinite at the plane and locate the plane at z = 0.
Quantum Mechanics II Consider the linear potential V = al.]. Use a Gaussian = exp(-Bx?) as the trial wave function, and calculate the ground state energy with the variational principle. De- termine the parameter B which minimizes the energy, and find Emin Express Emin = f x (hop/2m)1/3, and give the numerical value of the factor f. This is the upper bound of the true ground state energy, E Compare Emin with the exact result, E. = 1.019 (1?o?/2m)/3, and...
