Superfluidity in graphene multilayers... A new quantum phenomenon in bilayers of graphene predicted by David Neilson and his co-workers has been observed.   In 2018 Physical Review Letters published an article by a University of Texas at Austin experimental group confirming a theoretical prediction (Reference [34]) by David Neilson in collaboration with Andrea Perali (University of Camerino) and Alexander Hamilton (University of New South Wales, Sydney) that in a system of double bilayer graphene, and more generally in other semiconductors that can be made into atomically thin flakes, quantum  condensation and superfluid flow of condensed pairs of electrons and holes should occur at low electron densities.  This is a state of matter that had been searched for forty years, but not before observed.  Creation of this new quantum state in electronic devices, opens up novel opportunities for quantum-technological applications.
  

Supersolidity... is a counter-intuitive quantum state in which a rigid lattice of particles flows without resistance. It has not yet been unambiguously observed.
In Reference [10] David Neilson and co-workers show that a supersolid ground state of excitons in a double-layer semiconductor heterostructure should exist over a wide range of readily attainable layer separations larger than the separations typical in recent experiments.
 This supersolid conforms with the original supersolid proposed as a phase of Helium-4 by Geoffrey Chester, a solid with one particle per supersolid site.  This makes it quite distinct from alternative supersolid versions reported in cold-atom systems of a periodic density modulation or clustering of the superfluid.  
The new phase appears at layer separations much smaller than the predicted exciton normal solid, and it persists up to a solid--solid transition where the quantum phase coherence collapses.   The ranges of layer separations and exciton densities for the supersolid are well within reach of current experimental capabilities. 


Empty Optical Cavity... Modification, by the virtual photonic excitations in an empty cavity, of the properties of a two-dimensional semiconductor device with excitonic dipoles when the device is placed in the cavity.

    Short Bio

Born in Sydney, Australia, David Neilson completed his primary and secondary schooling at Geelong Grammar School, near Melbourne.
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 as a Fulbright scholar 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 (Stony Brook) in 1971.
He switched his research to Condensed Matter Physics, working with Gerald E. Brown jointly at Stony Brook and 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.
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 an Adjunct Professor. 
He has held visiting positions at the Niels Bohr Institute, (NORDITA Fellow), the Max Planck Institute, Stuttgart (Research Scientist),
Nottingham University (S.E.R.C. Visiting Fellow), 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 (founded 1336) University of Camerino and
Research Associate with the National Enterprise for NanoScience and NanoTechnology (NEST) Centre at the Scuola Normale Superiore in Pisa.

Since 2018 David Neilson has been Visiting Professor of Physics at the University of Antwerp.
In that position he has co-supervised the Ph.D. theses of four physics doctoral students from the University of Camerino within the agreement of the joint Camerino-Antwerp degree program.
He also acts as mentor for Erasmus students from Camerino visiting the University of Antwerp.


Holding Australian and Italian citizenship, he is fluent in English, Italian and French. 


Research Interests        
David Neilson has wide experience in the field of semiconductor theory and has studied exotic quantum phases of one- and two-dimensional systems found in semiconductor devices.  

His work has received more than 3,000 citations with an h-index of 31. 
Recent work has been on superfluidity in graphene bilayer and double transition metal dichalcogenides (TMD) monolayer devices.     

The recently experimentally confirmed prediction of superfluidity (Reference [34]) has attracted 250 citations.

In a superfluid, scattering is prohibited by quantum statistics, which means that bound neutral pairs electrons and holes (called excitons) can flow without heat-wasting resistance in new device structures of atomically thin semiconductors.  Immediate application is for devices in the computing industry.  These already use 8% of all electricity, a figure that is doubling every 10 years.  The task is to develop new types of electronic conduction without resistance in solid-state systems at room temperature.  This would form the basis of a new type of switching devices (transistors) with vastly lower energy consumption per computation than silicon CMOS devices.

David Neilson with his coworkers have 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 [74] with 180 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 the predictions in Reference [74].

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.
