Syllabus

See Exams for Syllabus pertinent to a specific test. Attached below is what sir has uploaded as Syllabus

Overview

Split into 5 Modules, the following :

Old Quantum Mechanics (QM)
Mathematical Foundations of QM
Wave Function & Schrodinger's Equation
(Application of) Schrodinger's Equation
Hydrogen Atom Problem

Prerequisites

The entirety of Maths for Physics 1 apparently, but I'm not sure about the accuracy of this statement, and how deep they expect. But to be clear, that includes:

Tensor Calculus
Complex Analysis (including but not limited to Residue Theory, Reimann Surfaces, etc.)
Fourier Series & Transforms
Function Spaces

Look at Maths for Phy 1 (PH20206) page for more info

In-depth - Out of Date, See Pic Above

1. Old Quantum Mechanics - Completed by 16th Jan

Including the math for all

Blackbody Radiation & The UV Catastrophe
Photoelectric Effect
Atomic Stability, including Double Slit Experiment
Compton Effect

2. Mathematical Foundations

Linear vector space, in the context of QM
Bra-Ket Notation, and operators

3. Wave Function

Wave function (duh)
Structure & explanation of the Schrodinger Equationn (Time Dependence & Independence)
Related concepts, like Potential.

4. (Applications of) Schrodinger's Equation

Free Particle
Particle in a box
Harmonic Oscillator
Tunnelling Problem

5. Hydrogen Atom Problem

Hydrogen Atom Problem (Very hard mathematically apparently)
Angular momentum & its algebra

Group Assignments

ONLY FOR BONUS MARKS

Context

The main grading of the course is done via MidSems, Class Tests & EndSems, which add up to 100M total. Beyond that, we have bonus marks of up to10M, based on group assignments.

Group Details

5 Members Maximum, unknown if there's a lower limit or if you can do alone.
One Written Solution is submitted by the group, representing all its members
The groups are up to you, and the final grouping should be informed to the professor in writing, in class.

Assignment Details

5 Assignments, each worth 2 marks, for each module
Usually will be given a week or two to submit.
Harder than class tests, but still solvable. A bit harder than tutorial.
