Nonlinear physics centre is engaged in theoretical and experimental interdisciplinary research in several diverse areas unified by the general concepts of nonlinear physics and photonics. This involves metaphotonics, nonlinear nanophotonics, topological photonics, harmonic generation, as well as the study of active metastructures and metasurfaces.
We specialise in understanding and utilising the quantum properties of light and matter. Lasers are arguably humanity's highest precision technology, and trapped laser-cooled atoms and ions can be highly controlled and isolated from their environment. This makes them a playground for understanding a range of quantum phenomena, as well as precision measurement devices in their own right.
Physical interactions between objects fundamentally depend on the geometry of their configurations and the topology of the space they are in. Our research develops the mathematics, algorithms and analysis methods for computing topological quantities from data, and explores the physical insights this brings.
We address fundamental questions such as the origin of Dark Matter and how it interacts with atoms and nuclei. We also develop quantum many-body modelling of subatomic systems to study fundamental processes, such as quantum tunnelling in nuclear fusion and fission, and in interacting electrons exposed to laser fields.
The current interests of the mathematical physics group, which spans the Department of Fundamental and Theoretical Physics and the Mathematical Sciences Institute, are primarily in the fields of exactly solved models in statistical mechanics and quantum field theory and in mathematical aspects of string theory and conformal field theory.
The Optical Sciences Group performs studies in extreme events, rogue waves and soliton theory. These are considered to be the most important discoveries in the twentieth and twenty first centuries mathematical and experimental physics.
