Spring 2021 Physics and Astronomy Course Offerings
Updated April 8, 2021
The department will offer one in-person class for physics majors who have achieved senior standing and who plan to graduate in the near future. All other PHY and AST classes will be held remotely.
A brief description of PHY 198 section is included below. Seniors who would like to register should contact Falicia Savala at firstname.lastname@example.org for a Permission To Add number.
With the exception of the PHY 198 section, all other Physics and Astronomy undergraduate classes in Spring 2021 will be entirely remote and in some cases asynchronous. We aim to make space for all students interested in our courses. In some ways remote instruction makes this easier, by removing constraints from lecture hall sizes and available lab setups. If a course you want appears full, please add yourself to the waitlist. That tells us there is extra demand, and it lets us communicate with you when new seats are added. If you have a nominal conflict with a course and need a PTA number, please contact either the course instructor or Amy Folz, email@example.com. Include the exact section you would like and details about the conflicting course.
PHY 198. Monte Carlo and Spontaneous Symmetry Breaking
2 credits, one 80 minute in-person class per week
Instructor: Richard Scalettar
Date/Time: Wednesdays 5:10-6:30pm
CRN: email firstname.lastname@example.org to request a PTA number
Phase transitions refer to very abrupt changes in properties of a system. At a more subtle level, they occur when a symmetry of nature is 'broken': a state forms which arbitrarily selects out a preferred configuration from many completely equivalent ones. In this course we will learn how to use Monte Carlo methods to understand quantitatively how magnetic, superconducting, and metal-insulator transitions occur in materials, including evaluating the critical temperatures at which they occur and the critical exponents which determine their 'universality class'. We will begin with the foundations of MC- how can a method using random numbers provide *exact* information!?- and then write codes to solve the Ising model and the onset of magnetic order. To check our codes, we will learn some of the analytic methods that can be used. Time permitting, we will learn how to map quantum problems in d dimensions onto classical problems in d+1 dimensions (Feynman's path integral method) and illustrate how the quantum phase transition of the d=1 Ising model in a transverse field is equivalent to the thermal phase transition of the d=2 Ising model. Useful background for this course includes an ability to code (in some language), statistical mechanics, and quantum mechanics. However, I will endeavor to minimize the requirements of previous background, in particular by running some separate sections which review material (including programming) for folks who find it useful.
Physics 7 - all sections offered remotely:
We plan to make room for all students who sign up for Physics 7, although not necessarily in their first-choice section. We will add more seats once waitlists are available. For Physics 7, attendance at quizzes during the first 25 minutes of lecture is mandatory, and Discussion/Laboratory attendance is also required. There will be one required midterm during a lecture. Contact the course instructor or DL TA if this will be a problem for you, and we will try to find a workable solution. We will be careful that the midterms do not conflict with those of ABI 102, ABI 103, or CHE 8B.
Physics 9 - all sections offered remotely:
We have added seats which we think will accommodate everyone who wants to take a Physics 9 course this spring. If necessary we will add more. The Physics 9 lectures will be recorded for asynchronous viewing. There will be office hours and problem solving during the lecture time slot. Attendance at the lecture time is optional except for an expected 3 midterm exams during the quarter. Laboratories will be entirely synchronous. The weekly one-hour Discussion section has mandatory attendance.
NOTE: PHY 198. Advanced Mathematical Techniques for Physicists, previously announced as an in-person class, has been canceled.
