We give a quantitative description of telescopes and microscopes. We explore the limits of geometrical optics and show that a wave theory of optics is needed to explain phenomena like diffraction and interference. We will briefly touch the Mach-Zehnder interferometer and the Michelson-Morley interferometer that is used in gravitational wave detection.

In the Spring semester we explore the electromagnetic nature of light, and present the polarisation (linear, circular, and elliptical). We introduce the concept of coherence, and use it to make a distinction between coherent light, such as that from a laser, and incoherent light from a light bulb or the Sun. Then we explore the properties of thermal light, including Wien's law, the Rayleigh-Jeans law, and how Planck reconciled their contradiction. Finally we discuss the implications of the constant speed of light, leading to the Lorentz transformations and the relativity of simultaneity.

Statistics covers the basics of Frequentist vs. Baysian approaches and data analysis, and applies them to data analysis tasks from a wide range of physics. It also looks at common statistical mistakes and fallacies and examines how to present data graphically and in writing.



Physics Problem Solving uses weekly problems classes to examine how physics knowledge can be applied to unfamiliar (often 'real world') problems to obtain quick, rough, but sound and useful conclusions/answers (often known as the 'back of the envelope' approach to problem solving). Problems cover the full range of core physics, requiring identification of which aspect of physics is relevant to a particular problem.

10 credits

Advanced Soft Matter and Biological Physics

Fascinating behaviour of soft matter and biological systems often occurs at thermal energy scales and can be described by statistical mechanical models. In addition, living biological matter is driven out of equilibrium due to internal biochemical sources of energy. Mathematical models and modern advanced experimental techniques are revealing the physical principles underpinning the biological world and the technological possibilities of complex soft materials.Much recent progress in soft matter and biology has been made thanks to the advent of advanced experimental  techniques which we will show are based on elegant physical principles. We will also study the physical principles underpinning the behaviour of complex soft matter and biological materials. We will describe phase transitions in multiple soft matter systems by calculating free energies. We will use random walk models to describe the shape of polymer molecules and the Brownian motion of colloids. We will also study the dynamics of polymers and the kinetics of polymerisation. We will then consider how polymerisation of protein filaments and action of molecular motors can generate forces in biological cells. This will involve us introducing concepts of systems that are in equilibrium versus out of equilibrium. Using a mathematical  framework we can describe behaviour at different length scales for example from the cytoskeleton to tissues, bacteria colonies and flocking. We will also investigate how the energy required for life is captured in photosynthesis.

We study examples of phenomena affected by general relativity, the rate of clocks and the redshift and bending of light in a gravitational field. Finally, we examine space time in the vicinity of the event horizon, the geometry of a non-spinning black hole, and the geometry of wormholes.

10 credits

Topics in Mathematical Physics

This unit will introduce students to advanced concepts and techniques in modern mathematical physics, in preparation for research-level activities.

It is assumed that the student comes equipped with a working knowledge of analytical dynamics, and of non-relativistic quantum theory.

We will examine how key physical ideas are precisely formulated in the language of mathematics. For example, the idea that fundamental particles arise as excitations of relativistic quantum fields finds its mathematical realisation in Quantum Field Theory. In QFT, particles can be created from the vacuum, and destroyed, but certain other quantities such as charge, energy, and momentum are conserved (after averaging over quantum fluctuations).

We will examine links between conservation laws and invariants, and the underlying (discrete or continuous) symmetry groups of theories. We will also develop powerful calculation tools. For example, to find the rate of creation of new particles in a potential, one must evaluate the terms in a perturbative (Feynman-diagram) expansion.

For details of the current syllabus, please consult the module leader.

Quantum Optics and Quantum Computing

Quantum computing is introduced through the fundamental concepts of quantum gates and circuits before moving to cover more advanced topics such as quantum programming, quantum algorithms and quantum error correction. These concepts are then applied by studying how programming quantum circuits can be done using cloud computers (e.g. using openQASM format) and the implementation of quantum algorithms (including examples) and quantum error correction using stabiliser formalism and graph states and quantum error correction codes.

The second part of the module covers quantum optics and quantum optical applications at the forefront of current research in the field. This includes topics such as weak and strong coupling of dipole sources in a cavity, single photon sources, protocols of quantum optical communications and linear optics computation. The module then progresses to quantum optical applications. Cavity electrodynamics is studied in the regimes of strong and weak coupling of matter excitations to the electromagnetic field in optical microstructures. This will lead to the physics of highly efficient single photon devices necessary for linear optics quantum computation. The effects of entanglement and quantum teleportation will be also considered.

Analytical Dynamics and Classical Field Theory

Newton formulated his famous laws of mechanics in the late 17th century. Later, mathematicians like Lagrange, Hamilton and Jacobi discovered that underlying Newton's work are wonderful mathematical structures. In the first semester we discuss this work, its influence on the subsequent formulation of field theory, and Noethers theorem relating symmetries and conservation laws.
In the second semester, Einsteins theory of gravity, General Relativity, will be introduced, preceded by mathematical tools such as covariant derivatives and curvature tensors. Einstein's field equations, and two famous solutions, will be derived. Two classic experimental tests of General Relativity will be discussed.

Directed reading in Physics and Astrophysics

This short module gives Masters students the opportunity to explore in detail a topic of interest to them, making use of research literature and/or graduate texts as appropriate.  Students will select the topic (subject to approval by the module leader) and be assigned a supervisor with appropriate expertise.  (Note: suggested topics may have to be rejected if no suitably qualified supervisor is available.)  Students will develop their understanding of the chosen topic by reading appropriate literature, as identified by the student with guidance from the supervisor.  If appropriate to the topic, students may also undertake other activities, particularly coding. 

   The module aims to encourage students to learn independently using research-level sources.  Consequently, there is no formal teaching.  Students are guided by weekly supervision sessions in which supervisors will discuss that week’s reading with the student, provide feedback and suggestions for further reading, help with any points that the student has found difficult to understand, and correct any misconceptions.  Students will keep a study diary in which they keep notes of their sources, explain topics in their own words, and perhaps work through problems.  In some cases, other activities, especially coding, may be undertaken to explore aspects of the topic.

Advanced Topics in Waves and Fluid Dynamics B

Waves and Fluid Dynamics are cornerstones of Applied Mathematics.  Both relate to the flow of fluids, i.e., propagation of information, which include not only gas (e.g., air) and liquid (e.g., water), but also in more complex media (e.g., lubricants and blood), and other materials or even the fourth state of matter: plasma.  The scientific principles and mathematical techniques involved in studying these are of inherent interest.  Wave motions give rise to well-known class of partial differential equations, and relate to concepts such as standing, progressive, and shock (i.e., nonlinear) waves; we can study these using Fourier series, Laplace transform and the powerful method of characteristics.  Viscous fluid flow gives rise to the Navier-Stokes equations.  The first semester will cover some of these ideas, while the second will move onto more advanced topics, such as three-dimensional flows, boundary layers, vortex dynamics, or magnetohydrodynamics.
