Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

Recent advances in the generation of well-characterized subfemtosecond laser pulses have
opened up unpredicted opportunities for the real-time observation of ultrafast electronic …

The generation of extremely short isolated attosecond pulses requires both a broad spectral
bandwidth and control of the spectral phase. Rapid progress has been made in both …

The accurate measurement of time lies at the heart of experimental science, and is relevant
to everyday life. Extending chronoscopy to ever shorter timescales has been the key to …

Manipulation of electron dynamics calls for electromagnetic forces that can be confined to
and controlled over sub-femtosecond time intervals. Tailored transients of light fields can …

The concerted motion of two or more bound electrons governs atomic and molecular, non-
equilibrium processes including chemical reactions, and hence there is much interest in …

In quantum systems, coherent superpositions of electronic states evolve on ultrafast time
scales (few femtoseconds to attoseconds; 1 attosecond= 0.001 femtoseconds= 10− 18 …

This tutorial presents an introduction to the interaction of light and matter on the attosecond
timescale. Our aim is to detail the theoretical description of ultra-short time delays and to …

Attosecond science has paved the way for direct probing of electron dynamics in gases and
solids. This review provides an overview of recent attosecond measurements, focusing on …
