BSc Physics with Theoretical Physics

Introduction to Quantum Mechanics

• Mathematics 2 PHYS10372 OR Introduction to Ordinary Differential Equations MATH11412;
• Vibrations & Waves PHYS10302;
• Quantum Physics and Relativity PHYS10121

The unit aims to introduce the framework of quantum mechanics, starting from discrete quantum systems and spin, their time dependence and the Schrödinger equation for the position representation, with examples from the infinite square well and harmonic oscillator.

On completion successful students will be able to:

1. Understand how quantum states are described by wave functions.
2. Deal with operators and solve eigenvalue problems in quantum mechanics.
3. Solve the Schrodinger equation and describe the properties of the simple harmonic oscillator.
4. Deal with algebra of angular momentum operators and solve the simple eigenvalue problems of an angular momentum in quantum mechanics.
5. Use quantum mechanics to describe the hydrogen atom.
6. Use quantum mechanics to describe the properties of one-electron at

Introduction to Quantum Mechanics

• Linear Algebra for Quantum Mechanics: State vectors, matrix notation, operators, eigenvalues and eigenvectors (matrix representation). 
• Fundamentals of Quantum Mechanics: Stern-Gerlach experiment, measurement (projective), commuting observables, uncertainty principle, entanglement, postulates of quantum mechanics. 
• Quantum Hamiltonians: Energy eigenstates, time evolution in QM. 
• Position representation: position and momentum operators, commutation relations and compatibility of different observables. 
• Time-dependent Schrödinger equation and time evolution, time-independent Schrodinger equation as an eigenvalue problem, particle in a box. 
• The harmonic oscillator: Stationary states, energy levels of simple harmonic oscillator, creation and annihilation operators. 
• Time-independent perturbation theory (1st order and 2nd order, including state vector corrections). Application to two-state systems and the harmonic oscillator.
• Barriers and tunnelling, WKB approximation.

Tuition fees for home students commencing their studies in September 2027 will be £10,050 per annum. Tuition fees for international students will be £40,300 per annum.

For general information please see the undergraduate finance pages.

All students should normally be able to complete their programme of study without incurring additional study costs over and above the tuition fee for that programme. Any unavoidable additional compulsory costs totalling more than 1% of the annual home undergraduate fee per annum, regardless of whether the programme in question is undergraduate or postgraduate taught, will be made clear to you at the point of application. Further information can be found in the University's Policy on additional costs incurred by students on undergraduate and postgraduate taught programmes (PDF document, 91KB).

The University of Manchester is committed to attracting and supporting the very best students. We have a focus on nurturing talent and ability and we want to make sure that you have the opportunity to study here, regardless of your financial circumstances.
