Haldane worked as a physicist at Institut Laue–Langevin in France between 1977 and 1981. In August 1981, Haldane became an assistant professor of physics at the University of Southern California,[8][9] where he remained until 1987. Haldane was then appointed as an associate professor of physics in 1981 and later a professor of physics in 1986. In July 1986, Haldane joined the department of physics at University of California, San Diego as a professor of physics, where he remained until February 1992. In 1990, Haldane was appointed as a professor of physics in the department of physics at Princeton University, where he remains to this day. In 1999, Haldane was named as the Eugene Higgins Professor of Physics. In 2017, he was named the Sherman Fairchild University Professor of Physics. In the period 2013–2018, Haldane also held a Distinguished Visiting Research Chair[10] at Perimeter Institute for Theoretical Physics.
As of 2011[update] he is developing a new geometric description of the fractional quantum Hall effect that introduces the "shape" of the "composite boson", described by a "unimodular" (determinant 1) spatial metric-tensor field as the fundamental collective degree of freedom of Fractional quantum Hall effect (FQHE) states.[13] This new "Chern-Simons + quantum geometry" description is a replacement for the "Chern-Simons + Ginzburg-Landau" paradigm introduced c.1990. Unlike its predecessor, it provides a description of the FQHE collective mode that agrees with the Girvin-Macdonald-Platzman "single-mode approximation".[14]
With David J. Thouless and J. Michael Kosterlitz, Haldane shared the 2016 Nobel Prize in Physics[4] "for theoretical discoveries of topological phase transitions and topological phases of matter".
Personal life
Haldane is a British and Slovenian citizen and United States permanent resident. Haldane and his wife, Odile Belmont, live in Princeton, New Jersey.[23]
His father was a doctor in the British Army stationed on the Yugoslavia/Austria border and there he met young medicine student Ljudmila Renko, a Slovene, and subsequently married her and moved back to England where Duncan was born.[24][25]
He received Slovenian citizenship at a ceremony at the Slovenian Embassy in Washington, DC on March 22, 2019.[26]
