The broad research interests of the academic and research staff in Theoretical Physics allow them to work on challenging problems of modern physics, such as high temperature superconductivity, quantum phase transitions, mesoscopic systems, dark matter, dark energy, origin of the matter-antimatter asymmetry, origin of neutrino masses, cosmic inflation, Big Bang cosmology, tests of Grand Unified theories and other physics beyond the Standard Model, the search for cosmological variation of fundamental constants, cosmic microwave background, atoms in strong fields, quantum chaos, the climate, and complex biological systems.

Our researchers in Theoretical Physics are involved in collaborations with numerous research groups in America, Europe, and Asia, such as CERN, EMBL, and several Max Planck institutes. Theoretical Physics is fortunate to have the support of the Gordon Godfrey fund, which finances visits to UNSW by world–leading theorists for the purpose of collaborative research as well as provides funds for an annual international research conference held at UNSW on exciting topics of modern science.
