THEORETICAL PHYSICS Research in the theoretical physics arena encompasses condensed matter, elementary particles, cosmology, accelerator science, geometry and classical fields.
Condensed Matter Theory Profs B Altshuler, V I Falko, C J Lambert, Drs V Cheianov, H Schomerus, and E McCann. Our activities range from developing fundamental condensed matter theories and studies of new materials, such as graphene, to modelling experimentally investigated devices. We perform broad studies of 2D electron systems and the quantum Hall effect; strongly correlated one- dimensional quantum systems, electronic properties of graphene and carbon nanotubes; transport and dynamics in molecular electronic systems. The development of theory of quantum dynamical systems (including microlasers and resonators) is the core activity of the Lancaster-based Marie Curie Excellence Team ‘Nanoelectrophotonics’ embedded in broader research on quantum dots, phase-coherent mesoscopic hybrid systems with superconducting, ferromagnetic and normal components, noise and counting statistics. Our activities contribute to worldwide collaborations with two dozen experimental nanoscience centres and theory groups, including Max-Planck-Institutes in Germany, IoP of Czech Academy of Sciences in Prague, Berkeley National Lab, and Columbia NY, Harvard and Cornell Universities in the USA.
Particle Theory, Astrophysics and Cosmology Prof D H Lyth, Drs K Dimopoulos, K Kohri, A Mazumdar, J McDonald and N Sahu.
Particle cosmology seeks to understand the Big Bang using elementary particle theory. Since the discovery of CMB anisotropy (1992), Lancaster has been recognised worldwide as a leading centre for the development of inflationary cosmology. We have been the source of many key ingredients of the now-accepted picture, such as the ‘epsilon-eta formalism’, the possibility of thermal inflation, and the curvaton hypothesis.
Lancaster has embarked upon a major new initiative in theoretical particle cosmology, with the intention of making it the leading centre for its study in the UK. With new observations expected in the near future from CERN’s LHC and ESA’s Planck CMB satellite, the cosmology group has the expertise to use the new information to gain fundamental insights into particle physics theory and the origin of the Universe. Please see our website for further information.
Electromagnetism, Geometry and Gravity Prof R W Tucker, Drs DA Burton, J Gratus, V Perlick, D C Christie, A Noble and S M Wiggins. Our work addresses difficult unanswered questions that arise when intense charged particle beams interact nonlinearly with their own intense electromagnetic fields. We aim to develop a fundamental understanding of the behaviour of charged media and their electromagnetic self- fields to be used in future accelerator and intense light- source design. As mathematical physicists, we make extensive use of coordinate-free geometrical concepts and spacetime notions to uncover the ramifications of our theories.
We collaborate with other groups throughout the world including those in major accelerator centres (CERN, SLAC, DESY) and other Universities. We also maintain a strong interaction with the Cockcroft Institute. Collaboration with the Cockcroft Institute offers a unique opportunity to gain involvement in some of the current major challenges in fundamental physics.
