Further Information
The broad research interests and qualifications of the academic
and research staff allow them to work on challenging problems
of modern physics, such as high temperature superconductivity,
quantum phase transitions, mesoscopic systems, quantum chromodynamics,
quantum gravity, violation of the fundamental symmetries and
tests of Grand Unification theories, the search for cosmological
variation of fundamental constants in the evolving Universe
predicted by string theories, atoms in strong fields, quantum
chaos, and foundations of statistical mechanics.
The
members of the Department are involved in collaborations with
numerous research groups in America, Europe, and Asia. The Department
is fortunate to have the support of the Gordon Godfrey fund
which finances visits to the University by world–leading
theoreticians for the purpose of collaborative research and
also provides funds for an annual international research conference
held at the University on interesting topics of modern science.
The
Gordon Godfrey fund also provides scholarships for postgraduate
students and prizes for undergraduate students who excel in
theoretical physics. Members of the Department give a continuing
course in theoretical physics (with no examinations) which is
aimed at making graduate students and other interested physicists
familiar with the main achievements and methods of modern physics.
PhD
graduates of the Department have found jobs mainly in research
and teaching positions in Australia, USA, and Europe.

Staff and Research Fields

Professor
Victor V. Flambaum MSc. PhD. DSc. Novosibirsk, FAA
My research interests include a number of challenging problems
in atomic , nuclear, elementary particle, solid state physics
and astrophysics, violation of the fundamental symmetries
(parity, time invariance), test of the theories of Grand
Unification of elementary particles and their interactions,
search for spatial and temporal variation of the fundamental
constants in the Universe from the Big Bang to the present
time, manybody theory and highprecision atomic calculations,
quantum chaos and statistical theory, hightemperature superconductivity,
mesoscopic systems and conductance quantization. 
Associate
Professor Chris J. Hamer MSc. Melb., PhD Calif.
Inst. Tech., DipCompSc Canberra, FAIP
My research interests lie in theoretical physics, at the
interface between particle physics and statistical mechanics.
We study quantum lattice models, which may represent atomic
spins in a magnet, electrons in a superconductor, or quarks
confined within the proton. We use powerful numerical techniques
to compute the properties of these models, and try to match
them to experimental data. Some current topics of interest
are novel ‘spin liquid’ phases in magnetic materials;
the exploration of possible mechanisms for hightemperature
superconductivity; and quantum Monte Carlo methods in lattice
gauge theory. 


Professor Gary P. Morriss BMath. N’cle (NSW),
PhD. Melb.
The interface between nonequilibrium statistical mechanics
and dynamical systems is my primary research interest. The
use of deterministic thermostats has allowed the development
of response theory for nonequilibrium steady states. Together
with new ideas and techniques from dynamical systems theory
we suggest that a new conceptual basis for a theory of nonequilibrium
steady states is possible. The nonequilibrium measure is
a singular SRB measure that can be approximated using periodic
orbit techniques. 
Professor
Jaan Oitmaa BSc. PhD. DSc. UNSW, FAIP
My work applies the principles of quantum mechanics and
statistical mechanics to systems of a large number of strongly
interacting particles, to understand and describe macroscopic
quantum phenomena such as magnetism and superconductivity.
I also work on mathematical models which exhibit phase transitions,
a striking and ubiquitous phenomenon which involves correlations
between particles over macroscopic volumes. These studies
are largely based on lattice models and use a variety of
analytic and numerical techniques requiring the use of supercomputers.
I am also interested in other aspects of the theory of condensed
matter, and theoretical physics more generally. 


Professor
Oleg P. Sushkov MSc. PhD. Doctor of Science
My major research
interests are in the field of manybody quantum physics.
This includes Nuclear Physics, Atomic Physics and Condensed
Matter Theory. The main results are: Precise calculation
of parity violation effects in heavy atoms, Prediction of
a huge enhancement of weak interaction effects in neutron
scattering, Theory of parity violation in nuclear fission,
Theory of the magnetic superconducting pairing in the Neel
state of a strongly correlated quantum antifferomagnet.
Current study is concentrated mainly on new types of quantum
phase transitions in strongly correlated electron systems.
This field has attracted a huge interest in recent years
because of its close connection to the problem of high temperature
superconductivity and because the technological progress
allows to create novel materials with highly nontrivial
quantum properties.
