Physics 45200 Quantum Optics and Quantum Gases

Day/Time: MW 9:00 - 10:20 am     
Location: KPTC 101     
Lecturer: Cheng Chin cchin@uchicago.edu     
Graders: 
Office Hours: TuTh 10:20 - 11:00 am @ GCIS E107

Focus: This course integrates quantum optics, quantum many-body physics, and atom scattering through lectures, discussions and computational projects. The course will offer fundamental understandings and collaborative simulation of essential many-body platforms:
Project 1:    Quantum Circuit
Project 2:    Hubbard Lattice Model
Project 3:    Multichannel Scattering
The emphasis is on physics-driven problem solving, controlled approximations, and hands-on numerical implementation, rather than black-box software use.

Prerequisite:
1.    Physics and math: Quantum mechanics, linear algebra, tensor products, approximation methods
2.    Basic many-body physics
3.    Working knowledge of Python or equivalent

Core Tools:
1.    Programming: Python (NumPy, SciPy), Qiskit, sparse matrices
2.    Visualization: Matplotlib, Plotly
3.    Web Apps: Streamlit or Panel (recommended)
4.    Version Control: Git + GitHub (shared repos)
