Career Summary

David Neilson is author of more than 100 refereed research articles, review chapters in books and refereed conference reports and editor of a number of review books.

Superfluidity in graphene multilayers... A new quantum phenomenon in graphene predicted by Neilson and co-workers has recently been observed.
In May 2018 Physical Review Letters published an article by a University of Texas at Austin experimental group confirming a theoretical prediction by David Neilson in collaboration with Andrea Perali (University of Camerino) and Alex Hamilton (University of N.S.W., Sydney) that in a system of "double bilayer graphene" at low charge carrier densities, there should appear a new quantum phenomenon, condensation and the superfluid flow of pairs of electrons and holes, a state of matter searched for forty years, but never before observed.  Creation of this new quantum state in graphene opens up novel opportunities for quantum-technological applications, some to be developed in the new FLEET Centre of Excellence.

Born in Sydney, 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 working 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 in Sydney as Senior Lecturer (Assistant Professor).  From 1985-1994 he was Associate Professor, and from 1995 until 2003 Professor of Physics at New South Wales.   He maintains his ties with New South Wales as a Visiting Professor.  He has held visiting positions at the Niels Bohr Institute, (NORDITA Fellow), at the Max Planck Institute, Stuttgart (Research Scientist), at Nottingham University (S.E.R.C. Visiting Fellow), at the International Centre for Theoretical Physics, Trieste, Italy (Research Director), Université de Paris VI (Visiting Fellow), and the Scuola Normale Superiore, Pisa (Visiting Professor). 

From 2005 to 2017 he was chiara fama Professor in Italy at the historic University of Camerino (founded 1336).  He was also Research Associate with the National Enterprise for NanoScience and NanoTechnology (NEST) Centre at the Scuola Normale Superiore in Pisa.

In 2018 David Neilson was appointed Professor of Physics at the
University of Antwerp. He is a Partner Investigator of the Australian Research Council Centre of Excellence “Future Low Energy Electronic Transport” (FLEET).

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 recent work has been on superfluidity in graphene bilayer devicesThe prediction of superfluidity (Reference [13]) has attracted over 50 citations.  He has also predicted new states of matter for electrons in coupled  bilayers in the form of a coupled electron crystalline solid or a charge density waves. Reference [53] with over 100 citations, has stimulated a large number of follow-up studies of bi-layers in zero magnetic field. 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. [37]. He developed comprehensive diagrammatic many-body calculations incorporating functional conserving techniques for conduction electrons.  He developed a quantum generalization of the classical glass equations 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]. 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.  He has studied the decisive effect that impurities have on the ground state of interacting electrons in quasi one-dimensional quantum wires.  Before taking up his chiara fama Chair in Italy, he 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.
