Significant themes in the group's work include supersymmetric theories, generalised symmetries and anomalies, amplitudes, holography and solitons. Supersymmetric theories provide a controlled environment for gaining a deeper understanding of field theory. Our work focuses on constructing new examples, both directly in field theory and from string compactifications, and understanding the geometric and algebraic structures characterising these theories. Symmetries play a central role in physics. An exciting new development is the discovery of generalised symmetries, transformations acting on extended objects. Scattering amplitudes are the basic observables in quantum field theory. They can have surprisingly simple structures; characterising these structures leads to remarkably different perspectives on the nature of quantum field theory. Holography provides a duality between field theory and quantum gravity, shedding light on both sides. Work in this area includes using the gravity side to perform calculations in strongly-coupled field theory, and using the field theory to understand the quantum structure of spacetime. Solitons are classical solutions of field theories, which play an important role in understanding the non-perturbative physics of quantum theories.
