Interests
Much of my research is focused on understanding the properties of frustrated systems. That is, systems where the internal interactions pull in different directions, making it difficult to identify a simple ground state. In some cases, this results in ground states with strong quantum entanglement and excitations with fractional quantum numbers, such as in the case of quantum spin liquids.I seek to predict how these systems should behave in experiment, and use this is a guide to help find new phases of quantum matter.
