###### Profiles

# Dr B. King

### Lecturer in Theoretical Physics

### School of Computing, Electronics and Mathematics (Faculty of Science and Engineering)

### Role

Lecturer and researcher in theoretical physics and Final-year senior personal tutor.

My lecturing is centred around applied mathematics, in particular classical mechanics, ODEs, vector calculus and computational mathematics. I teach modules in the School of Computing, Electronics and Mathematics, and in the School of Mechanical and Marine Engineering.

My research is focused on strong-field QED. This involves the study of light and charged particles in extremely intense electromagnetic fields such as one would find in the most intense laser pulses or in the very strong fields of magnetised neutron stars.

### Qualifications

Doktor der Naturwissenschaften (Dr. rer. nat.)

Universität Heidelberg (2010)

Master in Science: Physics with Theoretical Physics

Imperial College London (2006)

### Teaching interests

**MATH3606 - Classical and Quantum Mechanics (Module Leader)**

This module introduces advanced classical mechanics and the key ideas of quantum mechanics to students with a mathematics background. An overarching theme will be the key role of symmetry, both for classical motion and quantum behaviour.**MATH3628 - Maths Project (Supervisor)**

**MATH2604 - Mathematical Methods and Applications (Module Leader)**

Vector calculus is extended to higher dimensions and applied to a range of important scientific problems primarily from classical mechanics and cosmology. Differential and integral calculus is applied to the solution of differential equations and the orthogonal functions bases are constructed. The crucial mathematical concepts of integral transforms (Fourier and Laplace) and Fourier series are introduced.

**MATH257 - Computer Aided Mathematics (Module Leader)**

Students will be taught advanced mathematical techniques and their application using the MATLAB computer software package to solve engineering mathematics problems. The module will also introduce the students to the theoretical fundamentals of finite element analysis.

### Research interests

**Strong-field Quantum Electrodynamics: **

- Pair-creation and nonlinear Compton scattering in laser backgrounds

- Electromagnetic cascades in external fields

- Real photon-photon scattering

- Methodologies for computational simulation

When electromagnetic fields become very strong, calculations become difficult as the standard method of using perturbation theory can no longer be used and the processes are therefore more difficult to describe. However it also means that new and interesting phenomena can emerge, such as light-by-light scattering, which is forbidden classically. It is also thought that studying strong-field processes can help solve difficult outstanding problems in QCD (Quantum Chromodynamics) and Cosmology. The next generation of forthcoming laser facilities are hoped to be able to finally probe strong-field QED processes.
