Overview

Dr Matthew Davis' research interests are in the area of the quantum behaviour of ultra-cold gases and Bose-Einstein Condensation

He did his undergraduate studies in physics at the University of Otago in Dunedin, New Zealand, before completing his PhD at the University of Oxford in 2001 under the supervision of Professor Keith Burnett. His chief research interests are

methods for nonequilibrium dynamics of Bose gases formation of BECs generation of correlations in ultra-cold gases computational physics

Research Interests

  • Dynamical Quantum Field Theory for Bose Gases
    Calculating the physics of quantum many body systems is a notoriously difficult problem and must usually be tackled computationally. One of our interests is in a technique that utilises the fact that the lowest energy modes of a condensed Bose gas are highly occupied, and therefore can be well approximated as being classical in nature. This method is nonperturbative, and can be applied to problems such as the shift in the BEC transition temperature with interaction strength.
  • BECs in Optical Lattices
    BECs in optical lattices are beginning to probe the quantum nature of matter waves. Recent experiments have demonstrated the Mott-insulator phase transition, as well as the collapse and revival of the condensate wave function. We are interested in both quantum and thermal effects in lattices, including the re-establishment of coherence and superfluidity.
  • Growth of a BEC
    We are interested in applying quantum kinetic theory to the problem of BEC formation. Past calculations have generally shown good agreement with experiment, but some questions still remain. In particular one experiment has suggested that quasicondensate formation slows down the growth process.
