Areas of Expertise

Professor Dharma-wardana has worked on a wide variety of scientific topics, where the unifying theme is the application of the quantum theory, usually to many-body problems. His work focused on quantum theory, statistical mechanics, and solid state physicsassociated with Raman scattering, energy-relaxation and phonons in nanostructures, quantum Hall effect, the physics of nanotubes and graphene. He worked on a variety of topics such as surface passivisation, quantum dots, organic light-emitting diodes and related nanostructures, energy-relaxation etc., in collaboration with researchers at the NRC, Universities or research institutions in Montreal, Toronto, British Columbia, Livermore, Los Alamos and Paris. A main area of Prof. Dharma-wardana's research has been in many-body theory and plasma physics, often in collaboration with François Perrot of the French Atomic Energy commission. The neutral-pseudo atom model (NPA) for warm dense matter is one of their main contributions of great practical value where finite-temperature density functional theory has been used to formulate a rigorous quantum mechanical approach to hot ionized matter. Subsequently, the construction of the classical-map scheme for quantum systems is a ground-breaking work, leading to the formulation of the classical-map hyper-netted chain method (CHNC). This method has led to a new approach for the evaluation of properties of Fermi liquids and warm-dense matter.

His previous work on the density-functional theory of dense plasmas is now well-established in the NPA model. It has led to the development of methods for the first-principles evaluation of the equation of state, and the transport properties of dense plasmas. His contributions to the energy-relaxation of hot electrons in semiconductors and also in plasmas,have presented a new direction in the theory of non-equilibrium states of two-temperature charged fluids. His paper elucidating the unusual thermal conductivity of clathrates still attracts many citations. His contributions to surface science (e.g. reconstruction of the sulphur-passivated InP surface), nanotechnology, phonons in semiconductor structures, quasi-periodic systems etc., are well known and are contained in over 200 research publications. Dharma-wardana currently serves as a principal research scientist at the National Research Council of Canada, and is a professor of theoretical physics at the Université de Montréal. His most recent book on physics is entitled A Physicist's View of Matter and Mind, published in 2013 by World Scientific.
