Further Details For The Lectureship in Physics (ref L357)

The research interests of the successful applicant should cohere with existings strengths at Lancaster. An appointment was made in ultra-low temperature physics in 1994, however, and a further appointment in this area is not being envisaged now. Applicants with interests in the following areas are particularly encouraged:

1. Theoretical Physics.

On October 1st 1995, excluding the advertised position, the Lancaster theory group will comprise 4 full-time, permanent academic staff. In addition there are currently 7 Ph.D. students and 7 research associates. The theory group has published around 75 papers during the 30 past months. Examples of which are [1-9].

A brief summary of recent activity is as follows:

1.1 Condensed Matter Theory.

Current research involves a comprehensive assault on problems involving phase-coherent phenomena in hybrid, normal-superconducting nanostructures. Recent publications have addressed a range of topics including: Andreev interferometers and phase gradiometers, the suppression of electrical conductance by the onset of superconductivity, analogues of the Aharonov-Bohm effect in mesoscopic superconducting loops, the Josephson effect in weakly linked, superconducting dots and non-equilibrium transport in mesoscopic, superconducting islands. Several of the resulting predictions have recently been confirmed experimentally. For the future we shall develop a quantitative theory of Andreev interference effects in 2DEG-superconductor and magnetic-superconductor hybrids.

Other interests include high temperature superconductivity, mesosocopic magnetism, photonics, quasi-particle phenomena in superfluid $^3$He and localization.

Research is funded by the UK SERC/EPSRC, NATO, the MOD and the E.U. The group has excellent computing facilities and coordinates of a 14 institution Human Capital and Mobility network on "Quantum Coherent Dynamics of Phase Coherent Structures."

1.2 Mathematical Physics, Particle Theory, Gravitation and Cosmology.

The Mathematical Physics group currently applies methods of modern differential geometry, computer algebra and quantum field theory to problems in the theory of differential equations and gravitation. Recent publications have involved research into exterior differential systems of non-linear hyperbolic equations, constrained Hamiltonian dynamics, applications of non-Riemannian geometry to dilaton and galactic dynamics, effective low energy string theory, the Wheeler-de-Witt equation on non-globally hyperbolic manifolds and the theory of signature change. This research is currently funded by NATO and the EC Human Capital and Mobility programme.

Originally studied exclusively in relation to collider physics, particle theory is nowadays also studied in the context of the early universe. This exciting field of Particle Cosmology has been a major research activity at Lancaster for the past ten years. Both the more astronomical aspects of the subject and its contact with supergravity and superstring physics are studied. The research is funded by PPARC and the EC Human Capital and Mobility programme.

2. Nonlinear Physics and Noise.

The Lancaster Nonlinear Group operates as an international consortium of scientists with complementary expertise that can be brought to bear on topical problems of mutual interest in nonlinear physics and fluctuation theory. Recent investigations have included stochastic resonance and related phenomena, quasimonochromatic noise, the problem of large occasional fluctuations and transient multimodality. A new Lancaster/Manchester/Michigan/Pisa project on stochastically driven ratchets is just starting, as is a Kiev/Lancaster/Moscow/Saratov investigation of zero-dispersion nonlinear resonance.

During the last five years, the group has published more than 50 papers, involving the collaboration of authors from 10 countries, examples of which are [10-12]. The Lancaster end of the enterprise has been financed mainly by SERC/EPSRC and the EC, but with important contributions also coming from the Royal Society, NATO, the British Council and the Nuffield Foundation.

3. Advanced materials and photonics.

The physical properties of a wide range of inorganic, organic and polymeric semiconductors are being investigated. We have close links with industry and our work is both inter-disciplinary and international. Materials which exhibit luminescence or photoconductivity are of special interest together with the various electronic and photonic devices which can be made from them.

We have research expertise and grant support in the following areas:
