This module aims to deepen the understanding of quantum mechanics, building on a first encounter with the theory Second Stage. The emphasis will be on the mathematical foundations of quantum mechanics as well as the conceptual changes compared to classical mechanics.
Understand the abstract operator formalism of quantum mechanics for quantum states and observables
Understand the description of quantum mechanics in terms of position or momentum representations using "wave functions"
Describe the harmonic oscillator and angular momentum within quantum theory
Appreciate features of quantum mechanics distinguishing it from classical mechanics, e.g. tunnelling, Heisenberg’s uncertainty relation and commutation relations
Syllabus
Time-dependent Schrödinger equation: general solution in terms of the energy eigenstates; continuity equation for the probability.
Space of wave functions: position, momentum and energy as Hermitian operators; commutation relations; Fourier transform of wave functions; measurement of observables in quantum theory; Heisenberg’s uncertainty relation between position and momentum observables.
Free quantum particle on a line: momentum eigenstates; the propagator; the evolution of Gaussian wave packets.
Ehrenfest’s theorem and the classical limit.
Scattering problem in one dimension; discussion of tunnelling.
Dirac's bra-ket notation: harmonic oscillator with ladder operators.
Angular momentum: angular-momentum algebra; spherical harmonics.
Academic and graduate skills
Academic skills: students will learn a fundamental theory describing the physical world through combining their mathematical skills learned in earlier Stages.
Graduate skills: through lectures, problems classes and seminars, students will develop their ability to assimilate, process and engage with new material quickly and efficiently. They develop problem-solving skills and learn how to apply techniques to unseen problems.
