Professor Budakian's research focuses on developing highly sensitive tools, based on ultra-sensitive force detection, to study magnetism on the nanometer scale. These tools have been applied to explore novel phenomena in condensed matter systems, such as the detection of half-quantum vortex states in unconventional superconductors, imaging emergent order in frustrated magnetic systems, and imaging vortex fluctuations in superconducting arrays. He and his research group are also developing new techniques that combine magnetic resonance and ultra-sensitive force detection to study the interaction of small ensembles of nuclear and electron spins, with applications ranging from quantum information processing to imaging the structure of proteins and virus particles.
