Recent technological advances have enabled for the first time the synthesis and characterization of ultra short, ultra intense laser pulses that in turn permit investigations of laser-matter interactions in a new time regime, the regime of attosecond science. Attosecond science is a main "spin-off" of strong field (i.e., intense laser) physics, in which nonperturbative effects are fundamental. The capability exists at present to produce either single attosecond pulses or attosecond pulse trains.  These attosecond pulses open up new avenues for time-domain studies of multi-electron dynamics in atoms, molecules, plasmas, and solids on their natural, quantum mechanical time scale and at dimensions shorter than molecular and even atomic dimensions. These capabilities promise a revolution in our microscopic knowledge and understanding of matter.

A major role for theory in attosecond science is to elucidate novel ways to investigate and to control electronic and other processes in matter on attosecond time scales. The ingredients of appropriate theoretical formulations will likely include the fundamental concept of laser-driven, electron-ion rescattering, the unique aspects of few cycle (including single- and half-cycle) laser pulse–matter interactions, and a combination of perturbative and non-perturbative theoretical treatments for the various fields involved.

This workshop will take place five years after a 7-week workshop and international conference on attosecond science held during 31 July-15 September 2006 at the Kavli Institute for Theoretical Physics at the University of California at Santa Barbara, USA. It is therefore quite timely to examine the progress that has been achieved since 2006 and to outline new lines of investigation for the future. Thus, a main goal of the present  workshop will be to identify and clarify the main theoretical and computational challenges in describing attosecond-time-scale-driven atomic, molecular, plasma, and condensed matter processes by bringing together theorists from Asia, Europe, and North America for three weeks. In view of the considerable interest and progress in ultrafast intense laser science in China, it is expected that this workshop will facilitate the development of joint projects and collaborations among leading researchers in this new science, which is dedicated to the ultimate control of matter at the electron’s natural time scale: the attosecond. Finally this workshop should also be an excellent opportunity for educating a new cohort of young scientists in this new science of the 21st century.
