David Broun uses a variety of high frequency techniques to study the dynamical and thermodynamic behaviour of electrons in materials such as cuprate high temperature superconductors, heavy fermion systems, and a wide range of other novel metals, superconductors and insulators. Current research interests include: microwave spectroscopy of unconventional superconductors; field-tuned quantum criticality; 3D topological insulators; new techniques for probing spontaneous time-reversal symmetry breaking; electromagnetic properties near quantum critical points; and the use of vortex dynamics as probe of quasiparticles in unconventional superconductors.
