Born in Sydney Australia, David Neilson did his schooling at Geelong Grammar School. He studied Physics and Mathematics at the University of Melbourne, graduating with a B.Sc. with First Class Honours in 1968 under the supervision of Geoffrey Opat. He went to New York on a Fulbright scholarship in 1969 and completed an M.S. degree in High Energy Particle Physics and Field Theory under the supervision of Ben Lee at the State University of New York at Stony Brook in 1971. He then switched his research activities to Condensed Matter Physics, working with Gerald Brown jointly at Stony Brook and at the Niels Bohr Institute in Copenhagen.  His doctoral project was on the Many Body Problem for the strongly interacting quantum system of electrons in solids. Obtaining his Ph.D. in 1974 he took an N.S.F. research Fellowship at Northwestern University in Chicago where he worked with Chia-Wei Woo on the quantum solidification of Helium and on the possibility of the solidification of nuclear matter under the intense pressures found in neutron stars. 

In 1975 he took up a position of Assistant Professor at the University of Southern California in Los Angeles and in 1978 he moved to the University of New South Wales as Lecturer (Assistant Professor).  From 1985-1994 he was Associate Professor, and from 1995 until 2004 Professor of Physics at New South Wales.   He maintains his ties with New South Wales as an Adjunct Professor.  He has held visiting positions at the Niels Bohr Institute, (NORDITA Fellow) in 1978, at the Max Planck Institute, Stuttgart (Research Scientist) in 1980, at Nottingham University (S.E.R.C. Visiting Fellow) in 1986, at the International Centre for Theoretical Physics, Trieste, Italy (Research Director) in 1990, Université de Paris VI (Visiting Fellow) in 1991, and the Scuola Normale Superiore, Pisa (Visiting Professor) in 1992, 1993 and 1994-95. 

In 2003 David Neilson accepted a chiara fama Professorship in Italy and took up a Chair of Physics at the historic University of Camerino (founded 1336).  He is also Research Associate with the National Enterprise for NanoScience and NanoTechnology (NEST) Centre at  Scuola Normale Superiore in Pisa. 

 

Research Interests

David Neilson has wide experience in the field of semiconductor theory and has studied exotic quantum phases of the low-dimensional systems found in semiconductor devices.  His most recent work has been on issues of whether the bifurcation observed at finite temperature in the metal-insulator transition phenomenon be described by a suitable scaling theory, whether there are common elements between the low temperature behaviour, the bifurcation, and the "insulator-like" state, and whether a unified physical picture for two-dimensional transport over the full range of temperature and density can be developed for the metal-insulator transition phenomenon in 2D [1]-[3]. Most recently he has reported new evidence for the existence of a quantum critical point in 2D electric transport.  He has used Mori memory function techniques to study formation of the electron glass at zero temperature predicted new states of matter for electrons in coupled 2D bi-layers in the form of a coupled electron crystalline solid or a charge density waves [19]. Reference [19], with over 100 citations, has stimulated a large number of follow-up studies of bi-layers in zero magnetic field (see also Refs. [10]-[12], [14]-[16]). The predictions that a coupled crystal does form at relatively high densities were confirmed in numerical simulation studies. There has been a CECAM (France) conference devoted to coupled bi-layers in zero magnetic field resulting from Ref. [19]. He developed comprehensive diagrammatic many-body calculations incorporating functional conserving techniques for conduction electrons [21]. He developed a quantum generalization of the classical glass equations [20] with applications to conduction electrons, extended it to include impurities in interacting electron 2D layers, and showed that this could lead to a transition to a solid electron glass state [6]-[8],[17],[20]. He has worked on ground state, localization and transport properties in disordered electron 2D systems. He has studied the effect of strong correlations between electron spins in electron systems at low density [6],[18]. He has studied the decisive effect that impurities have on the ground state of interacting electrons in quasi one-dimensional quantum wires.  Before he took up his chiara fama Chair in Italy in 2003, David Neilson had had continuous funding as Chief Investigator of Major Research Grants from the Australian Research Council for an uninterrupted period of 25 years from 1978 to 2003.
