Description:

This course is an introduction to non-relativistic quantum mechanics. We will explore the basic formalism of the subject and consider selected examples and applications from atomic, solid state, nuclear physics and particle physics. Modern Physics (PHYS 201) and Classical Mechanics (PHYS 208) are prerequisites for this course. This course is the first semester of a two-semester treatment of the topic. Over the course of the first semester, we will work through most of part I of the text book (see below), including:

Required Math:

We will make extensive use of calculus, so you should have taken MATH 111, 112 and 213 (or 212).
We will also make use of some aspects of Linear Algebra and Ordinary Differential Equations. The needed topics from the these latter subjects will be introduced and reviewed as needed, however students who have taken, or are taking MATH 211, MATH 302 or PHYS 301, will find that those courses are useful.

All of the Linear Algebra that is needed in the course is reviewed in the Appendix of the textbook.

Grading Scheme:

There will be homework assignments, roughly every week, three in-class tests, and a final exam. The grades will be calculated based on either

    Homework       : 25% 
    In-class Tests : 45%  (lowest test grade will be dropped)
    Final Exam     : 30% 
or
    Homework : 25% 
    Final Exam:  75% 
For each student, the final grade will be calculated using both equations, and the result with the larger numerical grade will be the one used to determine the letter grade.

This procedure means that students who may have had difficulty with one or more of the in-class tests have the chance to make up for it with a good performance on the final exam; after all - what is relevant is how much physics you have learned at the end of the course!

Letter grades will be determined from the numerical grades using:

               A  92-100%    A-  88-92
   B+  84-88   B  80-84      B-  76-80
   C+  72-76   C  68-72      C-  64-68
   D+  60-64   D  55-60      D-  50-55
   F  < 50

Tests and Exam:

The tests and the final exam will be closed-book; you will be allowed to bring an equation sheet.

If you know you will miss a test due to a university-sanctioned event, please notify me by email well in advance. If you are ill on the day of the test, please contact me as soon as possible to make other arrangements. A makeup test may be administered.

The final exam will be held Tues. Dec. 21, 9:00 am - noon.

Text:

Our textbook will be:
   Introduction to Quantum Mechanics: 3rd edition
   Author: David J. Griffiths and Darrell F. Schroeter
   ISBN: 9781107189638
   Publisher: Cambridge University Press

Note: this is a new (third) edition of this book. The differences between this edition and the previous edition are rather minor, however some of the homework problems are different. If you want to use a previous edition, make sure that you can get access to the 3rd edition for homework problems. An eText version is available at reduced cost. Please be aware that the 'international' edition of the text (which is less expensive, and is in paperback) and is labelled for sale in only certain countries is not the same as the 3rd edition (there are some missing sections and the problems are not the same), so please avoid using this one.

Homework:

Homework assignments will be posted on Blackboard.

You can't properly learn physics just by listening to a lecture or watching someone else use it. You've got to do it yourself. To get good at it, you must practice. Doing the homework assignments will be integral to success in this course. Expect to have one homework assignment per week, for most weeks of the semester. You may work problems with others (but not copy each other's work!), and all students must turn in their own solution set.

For full credit, assignments must be turned in on their due date, which will always be on a Friday. Late assignments will be accepted until the following Friday, but the grade will be reduced by 50%. The graders for the course are Mohsin Jamil and Kevin Braga; their contact information is posted on Blackboard.

Important Dates:

  Last day of Add/Drop:    Fri. Sept. 10
  Last day for Withdrawl:  Mon. Nov. 1
  In-class Tests:          Wed. Oct. 6; Mon. Nov. 1; Wed. Dec. 1
  Final Exam:              Tues. Dec. 21, 9:00 am              

See BlackBoard and here for a schedule of material and when it will be covered.
Reading the appropriate sections of the textbook before the lectures over that material is strongly recommended.
I will keep the schedule updated if we fall behind or get ahead of schedule.

Electronic Access:

This syllabus, a course calendar, supplemental materials, and homework solutions will be posted on BlackBoard, accessible via myWM. Homework assignments will be announced in class and posted on Blackboard. Electronic access to the lecture materials is not a substitute for attending class to find out what is going on. I'll try to answer any email promptly, but please don't expect a reply after 9:00 pm.

Alternate Textbooks

I have posted a list of some useful alternate textbooks (at a similar level to our text), here: alternate texts.

Accessibility:

William & Mary accommodates students with disabilities in accordance with federal laws and university policy. Any student who feels s/he may need an accommodation based on the impact of a learning, psychiatric, physical, or chronic health diagnosis should contact Student Accessibility Services staff at 757-221-2512 or at sas@wm.edu to determine if accommodations are warranted and to obtain an official letter of accommodation. For more information, please see www.wm.edu/sas.

COVID-19:

We will do the utmost to help keep each other healthy. We will follow the current Healthy Together Committment of W&M's Path Forward regarding face masks, etc. I will be available for office hours both in person or via Zoom videoconference, depending on your preference.
