Overview

Background Magnetic flux emerges from the convection zone to the solar surface over an enormous range of spatial (100 km – 100,000 km) and temporal (seconds to months) scales. The turbulent nature of convection generates a continuous magnetic energy spectrum spanning over many orders of magnitude. The vast majority of magnetic flux detected on the solar surface is linked to global dynamo processes and the solar cycle. The presence of a non-zero local flux can indicate the existence of a local, surface dynamo that is independent of the solar cycle and plays a key role to the emergence, coalescence, fragmentation and cancellation of magnetic elements. The evolution and dynamics of these small-scale structures contributes to the energy balance of the solar atmosphere. It is believed that the small energy releases that arise from these structures, can hold the answer to how the temperature in the Sun’s outer atmosphere rises rapidly from a few thousand degrees in the surface to over one million degrees in the corona.

Project Description
The project will study the physical properties of small-scale magnetic elements in the lower solar atmosphere and quantify the processes at work. It will consider the brightness, spectrum and polarisation of light in selected spectral lines and continuum. It will use dedicated instruments have been constructed to measure the Stokes profiles with high polarimetric accuracy and sensitivity. State-of-the-art inversion techniques have been developed alongside the instruments to extract physical information from spectropolarimetric observations. We anticipate that the project will use observations from the 4m Daniel K Inouye Solar Telescope, the largest solar telescope in the world, where QUB has a leading role.

The main aims of the project can be summarized as follows:
• Acquire imaging spectropolarimetric datasets
• Determine the degree of polarization of small-scale structures in the solar photosphere
• Use inversion techniques to evaluate the properties of the magnetic and thermodynamic properties of the plasma
• Compare the magnetic energy with the radiative and kinetic energy losses
• Assist with the development of detector technology that push the limits of detectability of current instruments

Other information
• The student will work in collaboration with researchers at QUB, and other research institutes worldwide
Facilities to be used
• DESIRE, HAZEL, SIR (Inversion algorithms), Swedish Solar Telescope (La Palma), Daniel K Inouye Solar Telescope (Maui), GREGOR Telescope (Tenerife)

Research Information

Research Themes
Astrophysics (PhD/MPhil)

You’ll be involved in the search for distant supernovae and where they came from; study the asteroid and comet population in the Solar system; look for planets orbiting other stars in our Galaxy; study flares and other dynamic processes in the atmosphere of the Sun. You’ll have the opportunity to spend extensive periods at world-leading research centres such as the European Southern Observatory and NASA Goddard Space Flight Center.

At Queen’s we lead major European consortia and are supported by a multi-million pounds portfolio of research grants from a range of sources, including the UK Science and Technology Facilities Council, the Royal Society, and European Union.

Research Themes
Centre for Quantum Materials and Technologies (PhD/MPhil)

Human history is defined by the materials we use to underpin our technology: stone, bronze, iron, silicon. As we enter the emerging Quantum era, this impetus on materials and their link to technologies becomes even stronger. As a PhD student in Centre for Quantum Materials Technologies, you will be playing a part in the development of materials systems which will, in some way, define our technology for the future. How can this not be exciting? You will seek to reveal the physics of material behaviour at the boundary of current global knowledge and quantum limits, at the same time, become proficient in techniques for Quantum computation, materials growth, patterning, characterisation and theoretical modelling.

These skills are highly valued in high-tech companies and commercial research institutions, as well as in academic research settings. Our laboratories and computational facilities are extremely well-equipped for international-level research and our links to other research teams throughout the world in both academia and industry are strong and you should expect to travel, should you wish to, as part of your PhD experience.

Research Themes
Centre for Light Matter Interactions (PhD/MPhil)

Your research will involve identifying, and responding to, major open problems in laser- and electrically-produced plasmas, ultra-fast atomic and molecular physics, the interaction of ionising radiation and plasmas with matter (including biological systems), the physics of antimatter interactions with atoms and molecules, and the description of strong field laser interactions with atoms and molecules.

You will address fundamental and/or practical questions related to the description of electronic excitations, optical properties of matter, and the interaction between electric currents, heat and light. Your theoretical activity will imply the development and programming of novel simulation methodologies to model such processes. Experimentally, you will employ local, national and international facilities, including some of the most powerful laser systems worldwide ,while benefiting from transferring your research findings into the industrial and medical sectors.

Postgraduate research programmes within CQMT provide experience and training in state-of-the art academic research: many of our research strands are world-leading, as evidenced by performance in REF2021. In addition, most of our postgraduate researchers are exposed to functional materials and photonics in major multinational companies.

Physics costs

Depending on the area of research chosen there may be extra costs which are not covered by tuition fees.

Additional course costs

All Students

Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.

Bench fees

Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
