Results in brief
Final Activity Report Summary - TDRMX (Time-dependent R-matrix)
The development and implementation of an ab-initio theoretical approach for the handling of the interaction of atomic and molecular systems with strong and ultra-short electromagnetic (EM) fields has been the subject of the present project. The method is developed in detail and applied in the case of hydrogen. The complete theoretical framework which describes the full linear and non-linear dynamics for the case of multi-electron systems has been developed as a basis for the implementation of the method in these complex systems. In terms of the EM field characteristics the applicability of the theory ranges from the far infrared (fraction of eV) to x-ray (Kev) spectral band and pulse durations from attoseconds to hundreds of femtoseconds (1 femto-second is a millionth-billionth of a second and 1 atto-second is a thousand times shorter still). In addition, a novel numerical approach has also been developed which consists in the merging of two major numerical algorithms in solving a multi-dimensional partial differential equation (PDE). To the best of our knowledge this numerical approach is the first of its kind, at least in the area of theoretical Atomic, Molecular and Optical (AMO) physics.

Project objective
We propose a project in the research field of the interaction of electromagnetic (EM) fields with complex atomic systems.Current and ongoing developments on sources of EM coherent radiation with super-intense peak power and/or ultra-short duration (of at to second scale) at frequencies from the far infrared (fraction of eV) to hard X-rays (keV) makes the present proposal a timely and essential one.The theoretical framework applies to multielectron quantum systems such as quantum dots, atoms, charged ions and molecules, systems that is known to be of particular importance in cutting edge research areas such as nanoscience, atomic and plasma physics as well as quantum chemistry.In view of the latest technology developments the implementation of the present project can also contribute to the improvement of these sources through the characterization of the fields by predicting non-linear ionization yields (directly related with second-order autocorrelation measurements) and energy/angle resolved photoelectron spectroscopy.By drawing together our complementary expertise around a well-defined subject, through a very successful theoretical approach, namely the R-matrix approach, this project is aimed to solve challenging problems, in atomic, molecular and optical (AMO) physics.To accomplish this objective, it will be indispensable to merge methods from quantum and computational physics, thus demanding development of numerical algorithms on high-performance architectures.The host institution- is for several years actively contributing in breakthroughs in the field of the AMO physics- is participating in a number of related European projects and- has an excellent record in incubating successful careers.The framework of this synergetic effort provides ideal conditions for a multifaceted training in terms of research methods, project management and knowledge transfer for the fellow, vital for his future scientific career and professional maturity.
