Dale J. Van Harlingen (born July 22, 1950) is an American condensed matter physicist.
Education and career
Van Harlingen graduated from
Ohio State University with a bachelor's degree in 1972, a master's degree in 1974 and a doctorate in 1977. As a postdoc he spent a year at the
Cavendish Laboratory in Cambridge, England and three years with
John Clarke at the
University of California, Berkeley, where he did research on non-equilibrium superconductors and DC electronics with
SQUIDs. Van Harlingen became in 1981 a professor at the
University of Illinois at Urbana-Champaign (UIUC) and is now a professor of physics at the UIUC's Laboratory for Materials Research and the NSF Science and Technology Center for Superconductivity.[1][2]
Van Harlingen does research "on the physics of superconductor materials and devices and on the application of microfabrication, cryogenic, and superconductor electronic techniques to problems of fundamental interest in condensed matter physics."[1] He and his team created innovative scanning probe instruments, especially, the Scanning SQUID Microscope which does imaging of vortex configurations and dynamics in superconductor systems. After
high-temperature superconductivity was discovered in 1986, Van Harlingen and his colleagues pioneered the phase-sensitive SQUID interferometry technique which enabled the verification of the exotic
d-wave symmetry.[3] In fundamental experiments, with
David Wollman,
Donald Ginsberg and
Anthony Leggett, he determined the symmetry properties of the order parameter in high-temperature superconductors involving some copper oxides.[1] The discovery of such symmetry properties caused a huge research effort to understand the exotic d-wave symmetry and its relation to the mechanisms of unconventional superconductors.[3]
