Dale J. Van Harlingen

Dale J. Van Harlingen (* around 1949) is an American solid-state physicist.

Van Harlingen studied at Ohio State University with a bachelor's degree in 1972, a master's degree in 1974 and a doctorate in 1977. As a post-doctoral student , he spent one year at the Cavendish Laboratory in Cambridge and three years with John Clarke at the University of California, Berkeley , where he researched non-equilibrium superconductors and DC electronics with SQUIDs . In 1981 he became a professor at the University of Illinois at Urbana-Champaign and is there at the Laboratory for Materials Research and at the NSF Science and Technology Center for Superconductivity.

He deals with superconductivity and electronics based on it with applications in solid state physics. Among other things, he researched quantum noise and macroscopic quantum tunneling in Josephson junctions and SQUIDs, phase coherence in superconducting arrays and superconductors in non-equilibrium and was significantly involved in the development and application (for example of charge transport in mesoscopic systems) of scanning tunneling microscopy with SQUIDs. In fundamental experiments with David Wollman , Donald Ginsberg and Anthony Leggett , he determined the symmetry properties of the order parameter in high-temperature copper superconductors. He also deals with other unconventional superconductors (such as those with heavy fermions), mesoscopic systems, vortex dynamics in superconductors, and techniques of micro- and nanofabrication of superconducting systems.

In 1998 he and John R. Kirtley , Donald Ginsberg and Chang C. Tsuei received the Oliver E. Buckley Condensed Matter Prize for phase-sensitive experiments to elucidate the orbital symmetry of the pair wave function in high-temperature superconductors (laudation). He is a Fellow of the American Physical Society (1996), the National Academy of Sciences (2003) and the American Academy of Arts and Sciences (1999).
