Department of Physics

Applications are invited for a 3 year EPSRC Studentship in the Department of Physics at Heriot-Watt University.

The research subject is in the areas of Nonlinear Optics, Nonlinear Dynamics and Chaos, and Laser physics, in either experiment or theory, or a combination of the both. Possible projects are:

  1. Experimental studies of optical phase conjugation and high power CW lasers.
    The project is to investigate optical phase conjugation of CW radiation via stimulated Brillouin scattering in multi-mode fibre and its application to master oscillator power amplifier for CW high-power semiconductor laser sources.
  2. Theoretical and numerical studies of applied nonlinear dynamics and chaos.
    The project may be one of the following two topics:
    1. Pattern formations and control of spatiotemporal chaos in nonlinear optical systems.
    2. Applied nonlinear dynamics --- time series analysis, production and applications.

The group at Heriot-Watt University has longstanding expertise in experiment and theory in the areas of nonlinear optics, fibre optics, laser physics and devices, and nonlinear dynamics and chaos. The PhD programmes will be supported by the group's well-equipped laser/fibre optic laboratories and dedicated computer facilities.

Informal enquiries may be addressed to Professor R.G. Harrison on 0131-4513033 or Dr. W. Lu on 0131-4513024 ( Applicants can send their CV and other relevant materials to

Nonlinear hydrodynamic instability and laminar-turbulent transition of high-Reynolds number flows

Applications are invited for an EPSRC funded studentship to study at the Department of Mathematics, Imperial College, leading to the degree of MPhil/PhD. The project is in the general area of nonlinear hydrodynamic instability and laminar-turbulent transition of high-Reynolds number flows, but with particular emphasis on supersonic boundary-layer flows.

Laminar-turbulent transition is one of main streams in fluid mechanics, and has been the subject of active research for many years. In many circumstances, transition is initiated by small-amplitude disturbances, followed by a sequence of complicated nonlinear events. The fact that transition takes place at relatively high Reynolds numbers allows us to use and develop effective mathematical techniques. Recent research in this direction has successfully explained many qualitative features of the nonlinear stages. This project is (a) to continue our research by performing refined analyses with the aim of making quantitative comparisons with available experimental data, (b) to extend our theoretical studies to supersonic flows, and thus to provide further guidance for further numerical and experimental investigations.

The project involves both asymptotic analysis and numerical computation, and will be supervised by Dr X. Wu. More details about the project can be found on the World Wide Web site:

The proposed starting date is 1 October 1997, or as soon as possible thereafter.

Potential applicants must have at least a 2.1 degree in mathematics or physics, with a background in continuum (fluid or solid) mechanics. Knowledge of numerical methods and programming would be advantageous. For further details, please contact Martina Delaney (Postgraduate Admission), Department of Mathematics, Imperial College, 180 Queens Gate, London SW7 2BZ.

Two PhD studentships

Two PhD studentships are available for research into different aspects of Combustion Theory at UMIST. Regulations connected with EPSRC-funding require that the studentships are only made fully available to British students. Citizens of other EU countries would only have their fees paid, needing to find additional support for living costs. Non-EU citizens would not be eligible at all.

The two project titles are:

Memory Effects in the Propagation of a Flame
Moving Boundaries with Non-Monotonic Curvature-Dependent Propagation Speed.

Further brief descriptions of the nature of these projects are available via the web page

Anyone who is eligible and interested in applying for either of these studentships should contact:
