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 wave-mechanics description of quantum mechanics and its classical limit.
Understand the abstract operator formalism of quantum mechanics and its application to simple harmonic oscillator.
Appreciate features of quantum mechanics distinguishing it from classical mechanics, such as tunnelling and Heisenberg’s uncertainty relation.
Syllabus
The time-dependent Schrödinger equation: the general solution in terms of the energy eigenstates; continuity equation for the probability.
The space of wave functions: the position, momentum and energy as Hermitian operators; commutation relations; the Fourier transform of the wave function as the momentum representation; measurement postulates for energy, position and momentum; Heisenberg’s uncertainty relation between the position and momentum.
Free quantum particle on a line: momentum eigenstates; the propagator and the evolution of the Gaussian wave packet.
Ehrenfest’s theorem and the classical limit.
Scattering problem in one dimension; discussion of tunnelling.
Dirac’s bra-ket notation; the simple harmonic oscillator with ladder operators.
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.
