Frederick Duncan Michael Haldane (born September 14, 1951 in London ) is a British physicist who works in theoretical solid-state physics . In 2016 he received the Nobel Prize in Physics (together with David J. Thouless and J. Michael Kosterlitz ) for research on the theory of different topological phases of matter .

Life

Haldane studied at Cambridge University ( Bachelor 1973), where he received his doctorate in 1978 . From 1977 to 1981 he was at the Laue-Langevin Institute . 1981 to 1985 he was an assistant professor at the University of Southern California . From 1985 to 1987 he was at Bell Laboratories . From 1987 he was a professor at the University of California, San Diego , and from 1990 at Princeton University . There he is Eugene Higgins Professor of Physics .

Haldane investigated the quantum theory of magnetism in solids and many-particle problems in solid-state physics using non-perturbation theory methods, including the quantum Hall effect , Luttinger liquids , anyons (particles with unusual statistics) and one-dimensional integrable systems. To explain the fractional quantum Hall effect, he proposed in 1982 an extension of Robert Laughlin's model , whose wave function was not defined for all fractional fill factors. In 1983 he suggested (surprisingly at the time) the existence of a Haldane gap (gap in the spectrum of excitations) for integer spins in one-dimensional antiferromagnets (the gap does not exist for spin 1/2 excitations). With a work from 1988 he is considered a pioneer of topological solid-state phases, which later became relevant with the discovery of topological insulators . He introduced a graphene- like two-dimensional model that showed a quantum Hall effect in the absence of external magnetic fields. The model was taken up in 2005 by Charles Kane in his pioneering work on topological isolators.

Memberships and honors

In 1993 he received the Oliver E. Buckley Condensed Matter Prize , in 2012 the Dirac Medal of the International Center for Theoretical Physics and in 2016 the Nobel Prize in Physics (together with D. Thouless and M. Kosterlitz). From 1984 to 1988 he was a Sloan Research Fellow . He is a Fellow of the Royal Society , the American Academy of Arts and Sciences (1992), the National Academy of Sciences (2017), the American Association for the Advancement of Science , the American Physical Society, and the Institute of Physics .

From 1990 to 1999 he was on the advisory board of the Aspen Center of Physics and from 1985 to 1990 its trustee.
