Prof Stewart Boogert/Prof Glen Cowan/Dr Daniel Bedingham - Astrophysics Projects – Preference given to Astrophysics Students
- Optimising imaging with the RHUL 12-inch telescope
Taking detailed images of astronomical objects like stellar clusters, nebula and galaxies requires careful optimisation of the RHUL 12-inch telescope. This includes measurement of the telescope tracking drift, smallest best achievable focus, focus with different filters and flat fielding. The ultimate aim of this project is to determine the limiting factors to taking the best possible images with the RHUL teaching scope. There is possibility to develop new measurements and data analysis in Python as well as astronomical observations.
- Solar Limb darkening and spectra
The Sun is the only star which can be studied in detail. A feature of the Sun which has been long known is that it is darker at the perimeter compared to the centre. By measuring the variation in the brightness of the Sun across it’s diameter it is possible to measure the temperature of the Sun as a function of optical depth. The temperature and other properties of the Sun can be determined from taking spectra of Hydrogen lines. This requires coupling a spectrometer to the telescope and fitting Gaussian and Lorentzian line profiles. Students will develop image analysis in python and least squares fitting of functions in Python.
- Lunar and planetary imaging
The moon and planets are bright objects to image within the solar system. The main obstacle to capturing clear images of the moon and planets is distortion by the atmosphere. This distortion can be measured by taking a rapid sequence (at 10 to 100 Hz) of photographs and performing a 2-dimensional Fourier transform and selecting and adding only the sharpest images. Measurements can be taken with a mobile telescope away from the heat of Tolansky Laboratory and other buildings on campus. You will develop video processing and analysis codes in Python and the ultimate aim is to take the best possible image of a planet. A possible extension would be the measurement of planetary spectra.
Dr Stephen Gibson - Accelerator Physics
- Simulations of laser particle beam interactions for medical and other applications
Non-invasive laserwire diagnostics to measure the properties of relativistic particle beams have been developed in recent years at the John Adams Institute for Accelerator Science at Royal Holloway, and demonstrated at Linac4, the new injector for the Large Hadron Collider at CERN. Software tools have been developed to simulate the interaction of the laser with the hydrogen ion beam and calculate the yield of neutralised particles. This project will extend the existing simulations to study novel diagnostics methods and/or the possibility of using a laser to generate and control a particle beam for medical and other applications. Some experience in python / C++ code would be useful and / or would be gained throughout the project.
Prof David Heyes
- Molecular Dynamics Simulation and transport coefficients of liquids
For over 50 years the computer simulation technique of Molecular Dynamics (MD) has proved an invaluable tool in understanding liquids and solids. MD acts as a bridge between theory and experiment, and shares some characteristics of the two approaches. The MD method involves solving Newton's equations of motion of a group of interacting model molecules by a time stepping procedure. This project will involve writing an MD program in either Python or C++ to simulate a simple liquid. The code you will write will be used to compute a range of important physical properties. These will include the self-diffusion coefficient of the molecules and possibly other transport coefficients. Computer programming and problem solving skills will be developed. Aspects of the statistical mechanics of liquids will be learned.
- Molecular Dynamics Simulation of confined liquids
There are many situations in nature and technology where a liquid is confined by walls (e.g., synovial fluid in body joints, and lubricants between bearings in engines). The physical properties of confined liquids can be quite different to those in the bulk. Liquids can be modelled using what are called 'particle based' computer simulation techniques, which treat the liquid at the individual molecule level. Many interacting molecules are considered in the simulation. For example, the technique of 'Molecular Dynamics' (MD) follows the trajectories of the individual molecules by solving Newton's equations of motion for their (coupled) trajectories. The project will involve writing an MD computer simulation code in either Python or C++. Some basic properties of liquids confined between walls, such as the density profile in the gap, will be calculated. Computer programming and problem solving skills will be developed. Aspects of the statistical mechanics of liquids in the bulk and in confinement will be learned.

This is a project with the Dark Matter Research group, focused on some of the instrumentation and methods used in dark matter search experiments. The project is lab-based, and will involve measurements with a Time Projection Chamber (TPC) in the RHUL Dark Matter Lab. (A TPC is a large-volume gas detector used to detect and track charged particles in 3D.)

Dr Xavier Rojas - Condensed Matter / Low Temperature Physics
- Hydrodynamic Quantum Analogy
A recent discovery shows that a droplet bouncing at the surface of a vibrating fluid bath could interact with its own wave field in such a way that it exhibits quantum-like behaviour. While these features were previously thought to be exclusive to the microscopic world, they can now be observed using this quantum analog system (see https://www.youtube.com/watch?v=WIyTZDHuarQ ). The project will involve building a low-cost apparatus to realise this experiment and find the regime of parameters where quantum-like features can be observed. The student will learn problem solving and data analysis skills.

Dr Giovanni Sordi - Theory of Condensed Matter
- The Ising model: a gateway to phase transitions and critical phenomena
The Ising model is the archetype of systems that exhibit a phase transition and has inspired generations of physicists. This theory project approaches the statistical mechanics and computational physics of the Ising model. This project requires a good understanding of statistical mechanics, and enthusiasm for mathematics and computation. Attending PH3210 and PH3710 is strongly recommended.
Prof Pedro Teixeira-Dias - Particle Physics
- Time evolution of quantum-mechanical wave packets in 1D
The aim of this project is to write a computer program that calculates the time-evolution of a quantum-mechanical particle in one dimension, for different choices of potential. The student will use wave packets to describe a non-relativistic particle of non-zero mass m and momentum p. The program will be used to prepare plots of the probability density for the particle, as a function of time. Using the program the student will then demonstrate some of the following: dispersion of the wave packet, scattering at a potential step, tunnelling through a barrier, etc.
- Numerical simulation of a fission chain reaction in a nuclear pile
The aim of this project is to write a computer program to implement a numerical simulation of a fission chain reaction in a 2D nuclear pile. A real nuclear pile -- in order to be able to sustain a nuclear chain reaction with a steady release of energy -- must include different components: fissionable fuel, a neutron moderating material, and "control rods" for neutron absorption. A basic output of the program will be the energy released as a function of time. Once the program has been written the student will be able to use it as a tool to investigate: what are the conditions required for achieving a steady-state energy release; how the dimensions of the pile affect its energy output; how the density, or geometric configuration, of the pile components affects the performance of the pile, etc.
Computer programming skills are a pre-requisite for both projects.
