## Course Overview & Objectives

Having mastered the foundations of Quantum Mechanics, this course explores advanced and emerging topics through critical reading of the primary literature. By the end of the course, you will be able to evaluate, propose and carry out critical tests of ideas and methods directly from the literature.

## Grading & Due Dates

Your work will be graded based on homework assignments (20%), participation in class discussion (20%), and two exams (30% each).

- Homework 3 - DFT Due Thurs., Apr. 10
