Dear Colleague,

There is a three year postdoctoral position available at the University of
Surrey.  Please bring the advert below to the attention of anyone you think
might be interested.


Ian Melbourne

The following position is posted on the University of Surrey website at


University of Surrey


Department of Mathematics

RESEARCH OFFICER: Anomalous Diffusion in Deterministic Systems (Ref: 6531)

Salary £27,466 up to £31,840 per annum
(subject to qualifications and experience)

Applications are invited for an EPSRC postdoctoral position in the
Department of Mathematics on a project which will investigate probabilistic
aspects of dynamical systems.  Expertise in smooth ergodic theory and/or
probability theory will be an advantage.  The post is available from 1st
July 2008 or such other date as may be agreed, and the duration is up to 3

Project summary:  Certain gas models (planar periodic Lorentz flows) were
introduced as deterministic models for Brownian motion. A statistical law
called the almost sure invariance principle (ASIP) makes precise the
connection with Brownian motion.  Recent work established the ASIP for the
Lorentz flow.  Brownian motion has a characteristic growth rate of order
t^{1/2} where t denotes time. Currently, there is a great deal of interest
in anomalous diffusion with a different growth rate. The aim of this project
is the systematic study of anomalous diffusion (both subdiffusive and
superdiffusive) in deterministic systems. In the superdiffusive (fast) case,
this means proving the ASIP with Brownian motion replaced by a Levy process.
In the subdiffusive (slow) case, we will focus on Sinai diffusion where the
growth rate is of order (log t)^2.  The results will apply to infinite
horizon Lorentz gases and Bunimovich stadia. In addition, there are
applications in dynamical systems with symmetry, including spiral waves in
excitable media, and travelling waves.

You will join a vibrant mathematics research group at Surrey, whose
interests focus on themes in applied and nonlinear mathematics with
particular emphasis on the interface between pure and applied mathematics.
Research in applied mathematics at Surrey was rated 5A in the 2001 RAE. The
group has an active departmental seminar in Dynamical Systems with frequent
visits by external speakers from the UK and overseas.  Within the UK, there
are extensive research collaborations and contacts between the ergodic
theory group at Surrey and researchers in Bristol, Exeter, Imperial,
Manchester, Queen Mary and Warwick.  Further information and details of
current projects can be found at www.maths.surrey.ac.uk/research/

Informal academic enquiries are welcome and may be made to Prof Ian
Melbourne on I.Melbourne en surrey.ac.uk or +44 (0)1483 689643.

please contact Maria Drew on m.drew en surrey.ac.uk or +44 (0)1483 689135

Closing date for applications is 9th May 2008

The University is committed to an Equal Opportunities Policy
