PHYSICS 335 : Quantum Mechanics
2023 Semester Two (1235) (15 POINTS)
This course provides a comprehensive development of nonrelativistic quantum mechanics at the level of wavefunctions and the Schrödinger equation, with an elementary introduction to Dirac notation; it covers the mathematical formalism, its physical interpretation, and applications to simple examples such as 1-D square-well potentials, the 1-D harmonic oscillator, and the central potential. The full mathematical framework is set out, including eigenvalue problems, compatible and incompatible observables, measurement and Heisenberg uncertainty, and the related Bell inequalities. The course aims to provide a thorough understanding of how abstract formalism connects to the results of laboratory experiments. It provides a firm grounding in general principles for students planning postgraduate study in physics, in particular for those with an interest in advanced quantum mechanics, relativistic quantum mechanics and field theory, or quantum optics and quantum information.
Capabilities Developed in this Course
|Capability 1:||Disciplinary Knowledge and Practice|
|Capability 2:||Critical Thinking|
|Capability 3:||Solution Seeking|
|Capability 4:||Communication and Engagement|
|Capability 5:||Independence and Integrity|
- Explain how particles are represented in quantum mechanics by waves; describe the relationship between the energy and momentum of a particle and the properties of the wave representing it. (Capability 1)
- Discuss the physical meaning of the Schrödinger wavefunction and how it relates to the statistical interpretation of quantum mechanics and the fundamental difference between it and classical mechanics. (Capability 1 and 2)
- Write down the Schrödinger wave equation in its time-dependent and time-independent forms; explain how the energy representation is used to solve the time-dependent equation; apply the method to elementary examples. (Capability 1 and 3)
- Illustrate with examples how physical observables are represented by operators acting on wavefunctions; explain how the operator eigenvalues and eigenfunctions connect the mathematical formalism of quantum mechanics to measurements in the lab. (Capability 1)
- Derive the eigenvalue spectra of physical observables for exactly solvable examples like the square well potential, the harmonic oscillator, and a general angular momentum. (Capability 1 and 3)
- Outline the quantum theory of angular momentum (orbital and spin) and apply it to fundamental examples like the Stern-Gerlach effect, the central potential, and Bell inequalities. (Capability 1 and 3)
- Use Dirac notation. (Capability 1)
- Apply approximate methods, in particular time-independent and -dependent perturbation theory, to the solution of practical problems, e.g., in atomic physics, the interaction of atoms with light, and scattering from a potential. (Capability 1 and 3)
- Devise an appropriate mathematical strategy to solve a problem set out in physical terms, possibly consulting online resources and/or fellow students. (Capability 3 and 5)
- Present written solutions to assigned problems in a thoroughly argued manner, setting out the method used and all essential steps taken in a logical sequence. (Capability 4 and 5)

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.
At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.
Your feedback helps to improve the course and its delivery for all students.
Better communicate assessment expectations
The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.
Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.
The content and delivery of content in this course are protected by copyright. Material belonging to others may have been used in this course and copied by and solely for the educational purposes of the University under license.
You may copy the course content for the purposes of private study or research, but you may not upload onto any third party site, make a further copy or sell, alter or further reproduce or distribute any part of the course content to another person.
All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.
Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz
If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.
If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.
This should be done as soon as possible and no later than seven days after the affected test or exam date.
In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.
The delivery mode may change depending on COVID restrictions. Any changes will be communicated through Canvas.
Student Charter and Responsibilities
The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
