Research summary

The interaction of matter with laser fields of the order of or stronger than 1013W/cm2 has posed a formidable challenge to theorists within atomic, molecular and optical physics for a very simple reason. Up to the mid-1980s, when strong lasers became feasible, laser-matter interaction could be successfully described by taking the field as a perturbation. Such an approach, however, breaks down in the strong-field regime. As a direct consequence, our physical intuition concerning optical phenomena, which has been built upon perturbation theory with the laser field, needs to be re-evaluated. Furthermore, in order to treat such phenomena adequately, alternative theoretical methods are necessary.

Apart from its fundamental value as an area of science, strong-field laser physics has a wide range of applications, such as particle physics, plasma physics (in particular laser fusion), solid-state physics, novel X-ray sources, and attosecond science. In particular, attosecond science is an emerging, interdisciplinary field of research, in which the fact that most strong-field phenomena take place in the attosecond (10-18s) time range plays a very important role.  Hundreds of attoseconds are roughly the time it takes for light to travel through atomic distances. Hence, such phenomena can be used as tools to resolve, or even control, dynamic processes at the atomic scale. Concrete examples are the motion of bound electrons, or electron emission.

Current Research Interests:

Correlated multielectron processes in strong laser fields (laser-induced nonsequential double and multiple ionization), Attosecond pulses, Attosecond control of matter, Applications of high-order harmonic generation and above-threshold ionization, Molecules in intense laser fields, Non-Hermitian Hamiltonian systems.

Dr Carla Figueira de Morisson Faria graduated in Physics at the University of Sao Paulo, Brazil, where she also worked with Professor Vanderlei Bagnato on cooling and trapping of neutral atoms. Subsequently, she did her Ph.D. at the Max Born Institut, Berlin, under the supervision of Professor Wolfgang Sandner and Dr Martin Dörr, on the Interaction of Atoms with Intense Laser Fields and Ultrashort Pulses. Thereafter, she was a postdoctoral researcher at the Max Planck Institute for Physics of Complex Systems, Dresden (1999-2001), the MBI-Berlin (2002-2003), the Technical University Vienna (2002) and the University of Hanover (2003-2004). In 2005, she moved to the UK as a University Research Fellow at the Centre for Mathematical Sciences, City University, London, where she became a Lecturer in 2006. Since April 2007, she has joined the University College London as a Lecturer. Dr Faria has also been awarded an EPSRC Advanced Research Fellowship in October 2006.

Dr Faria is a specialist on theoretical strong-field laser-matter interaction. Since the mid-1990s, she has been developing theoretical models for several phenomena in this context, using both analytical and numerical methods. Dr. Faria has over 70 publications in this research area, in peer-reviewed journals and conference proceedings, and has participated in several conferences in Optical Physics, in many of which as an invited speaker. She is also a referee for several optics journals (Optics Communications, JOSA B, Journal of Modern Optics and Optics Letters), and has various collaborations with leading groups in the field. She also actively collaborates with scientists of other research areas, such as quantum optics and mathematical physics. Ongoing collaborations include Dr Andreas Fring (City University), the theory and experimental groups at the MBI-Berlin, Professor Maciej Lewenstein (Institute for Photonic Sciences, Barcelona), Professor Anna Sanpera (Universidad Autonoma, Barcelona), Dr. Henning Schomerus (Lancaster University), Professor Jon Marangos (Imperial College), and Professor Ingrid Rotter (Max Planck Institut, Dresden).
