Personal profile

Research Interests

Professor Halperin's research is focused on low-temperature physics (mainly superfluid 3He and topological superconductivity), NMR studies of high-temperature superconductors, and fluid transport in porous media. In recent developments, his research group has discovered how to engineer new thermodynamic phases of superfluid 3He in the confines of highly porous silica aereogel, thus bringing together the practical aspects of fluid confinement in porous media and the basic science of superfluidity. Much of this research involves close cooperation and collaboration with Professor Saul's theoretical group at Northwestern.
