Professor Denis Evans

PhD (ANU), BSc (Sydney), FRACI, FAA

Denis Evans graduated from The Australian National University with a BSc (hons) and received his PhD from the Australian National University. He has since held positions at Oxford University (1976-1977), Cornell University (1977-1978), The Australian National University (1978-1979), the National Bureau of Standards, Bolder, Colorado (1979-1980) before being appointed Fellow at the Research School of Chemistry in 1982.

He has been awarded fellowships of the Royal Australian Chemical Institute (1989) and the Australian Academy of Science (1994). Denis Evans received the Fulbright Fellowship to Colorado (1979), the Bronze Medallion, Australian Rheological Society (1988), the Distinguished Young Chemist Award, Federation of Asian Chemical Societies (1988), the Rennie Medal for Chemistry, RACI (1993), the Frederick White Prize, AAS (1990), the H. G. Smith Memorial Medal of the RACI (2000), the S.F. Boys-A. Rahman Lectureship, RSC (2000) and the Centenary Medal (2003) and the Moyal Medal (for Mathematics, 2004). He was appointed Professor at the Research School of Chemistry in 1990.

Research interests

Our research interests include nonequilibrium statistical mechanics and thermodynamics. We have been involved in the development of nearly all of the computer simulation algorithms used for the calculation of transport properties of classical atomic, molecular and short-chain polymeric fluids and lubricants. Algorithms that we have proposed are used to compute the viscosities, thermal conductivities, and diffusion coefficients for molecular fluids and fluid mixtures. We are known for deriving and experimentally confirming the Fluctuation Theorem.

This Theorem gives an elegant extension of the Second Law of Thermodynamics, so that it applies to finite systems observed for finite times. It also provides the first proof of the Second Law of Thermodynamics - it ceases to be a "Law". This theorem has important implications for nanotechnology. This result is exact for classical systems and quantum anologues are known.
