Research Interests

Systems of many particles evolving through the well-established theories of electromagnetism and quantum mechanics often collectively organise themselves in elegant ways. As a condensed matter theorist, my research aims to predict and understand such behaviour from a microscopic basis. I am particularly interested in systems where quantum mechanics and interactions play a crucial role. My group's research has a particular focus on collective effects in ultracold atomic gases. It is often straightforward to write down a simple and intuitive effective Hamiltonian which captures the relevant physics of these systems, but these Hamiltonians can be difficult to solve and can exhibit rich behaviour. Topics ('keywords') of current research include: interacting topological band models, non-equilibrium quantum dynamics, spinor condensates, Majorana fermions, and quantum vortices.
